How Will Children Grow Up to Be Manufacturing Professionals?

National Manufacturing Month October, 2016

Readers of a certain age will remember familiar patterns in the evolution of their childhood thinking about the inevitable “What Will I Be When I Grow Up?” question. For developing males, it went something like Cowboy-Fireman-Police-Doctor-Outfielder, while females might have followed more of a Nurse-Housewife-Model-Actress pattern.

And then, we actually grew up.

Cowboys and Housewives?  How quaint. Half a century ago well over half the popular entertainment programming featured cowboys and/or housewives. On a scant four broadcast channels, westerns and family sitcoms topped the ratings, while today those stereotypical roles have essentially become the washed-up driftwood on popular culture’s trash-strewn thousand-network beach. Some might say yesterday’s cowboys are today’s superheroes. And yesterday’s housewives have evolved into working sitcom moms. Let’s not pretend that Harriet Nelson and June Cleaver weren’t at least partially idealized.

In those not-so-distant days, in the real world, most people ended up working in manufacturing and supporting industries, so there always needed to be a coming-of-age shift from romantic fantasy to occupational reality, at least for those children maturing into members of the corporate and institutional workforce. The shifting demographic status of the housewife designation is another matter we’ll drop out of this thread, at least for the time being.

Image says October is National Manufacturing Month

And in any case, add up all the cowboys, firemen, police, doctors, outfielders, nurses, models and female actors, among those of us born in the 50s and 60s (and now in our 50s and 60s), and you may reach somewhere around 15% of the employment mix. The rest of us working stiffs—meaning most of us—are in sales, engineering, tech, healthcare, education, service and information, finance—and of course, manufacturing. Back in 1964, children didn’t put on Salesman suits, or Librarian tunics, for Halloween trick-or-treating.

It is October, and National Manufacturing Month is upon us once again in the USA. The good news is that technology, and its indivisible partnership with an exploding universe of information, is delivering to our developing workforce an amazing preview, and menu, for what to do with their lives.

Juvenile fantasies of adult vocations have shifted from old-west and domestic dreamworlds to superhero and comic-book roles, and easy and universal access to personal technology and its wide and clear window upon the world have made the transition to real-work evaluation and aspiration faster, more transparent, and way easier.

Five or six decades ago, information about working in engineering and the sciences would have been a relatively high grasp for any child younger than high-school age. That was when Choo-Choo-Charlie was an engineer, after all, and engineers drove trains.

Now, STEM programs, library services, public and private education, the internet, and popular culture have brought technical, technological, and vocational diversity to an ever-younger audience. Changes in the nature of work and industry itself are rigorously measured and predicted to bring notification of future employment trends to bear on career education and training tracks. The ensuing self-categorization lines up batches of ready workers preparing for the hot jobs of each next decade and generation. Nerds and geeks are cool now. We take our children to work once a year. Science, engineering, technical support, services, coding, and manufacturing technology are together an ever growing, ever evolving and interacting mesh of opportunities, many of which didn’t exist in their present form a generation ago.

One interesting manifestation of the parallel progress of technology and information is the Maker movement. Makers have their own events (Faires), mavens, magazines, Youtube channels, Wikis, networks, blogs, and podcasts.

In the Maker culture, information is shared, designs are traded, and creativity is celebrated. When DIY information began spreading out to millions of sites and documents and videos on the web, and useful technical instructions on how to repair, build and adapt complicated systems started the snowball rolling, it was only a matter of time before unexpected connections began to form. Innovation— integrating preconstructed modules, 3d printing, embedded software, traditional crafting, personal technology, open source sharing, and creative thinking— resulted.

Maker culture has already innovated and inspired numerous concepts and products that have been adapted for mass manufacturing, including environmental, energy, personal technology, household, transportation, and medical breakthroughs. It’s a major the new path for revitalizing American industry, and economic development for urban as well as rust-belt communities.

Who’s doing the making? Girls, boys. High school and college students. Farmers, 4H clubs, apartment dwellers, and tinkering dads in suburban mancaves.

And women. The ones already doing double duty at home and somewhere in an office. Make that triple duty, because they’re Making, too.

The Evolution of Asphalt Heating

Road. (n.) A wide way leading from one place to another, especially one with a specially prepared surface that vehicles can use.  “If you don’t know where you are going, any road will get you there.” Lewis Carroll

The first great roadbuilders, and engineers, were the ancient Romans, and parts of their roads survive to this day, over two millennia later. In the interim, the prepared surfaces of engineered roads have been made of mud, clay, brick, stone, and even wood block. Yet, for over a century now, by far the most common durable road surface has been the familiar black cement-and-aggregate mixture known as hot-mix asphalt. Other English-speaking parts of the world know it as bitumen, or macadam.

Ancient Roman road of Tall Aqibrin

This asphalt, first mined from pitch lakes on the island of Trinidad and similar deposits around the world, was originally mixed with gravel by hand labor in large metal trays placed over direct fire. Hard, hot work. As this natural asphalt became replaced over the years with an engineered formula derived from crude petroleum, both the heating process as well as the mixing technology evolved rapidly. Early mixers were adapted from the rotating drums used for cement mixing.

  And by the 1920s or 1930s, some asphalt producers, supplying material for both roadbuilding and for other uses such as roofing and pipe-dipping, had begun to use indirect heating to improve the uniformity and consistency of the end-product, as direct heat could be difficult to control. A 1931 technical article in The Journal of Industrial and Engineering Chemistry mentions steam, diphenyl vapor, and hot oil among the heating media already in use for indirectly heating asphalt tanks.

 The evolution continues to this day. The hot oil that those pioneers used back in the 1930s to heat asphalt tanks was a lubricating-oil base stock, designed not for heating but to protect metal surfaces and extend the life and improve operation of rotating equipment. These days, modern heat-transfer fluids are engineered specifically for high temperature service, and are derived from a variety of chemical families for rugged service, long life, and resistance to thermal and oxidative deterioration.

The heating equipment itself has also evolved a long way from those simple heated trays stirred by hand with long metal hoes. In the 60s producers moved beyond hot-oil heated asphalt plants, adding surge bins and storage tanks to allow more flexibility in meeting variations in demand. Innovators continued to develop other ways to extend the workability time and distance range of the product going out of the plant hot and ready for roadbuilding. Today, information systems, and advances in integrating computer systems into testing, supply, heating, environmental controls, and logistics are adding a whole new level of sophistication to asphalt plant operations.

Paratherm—Heat Transfer Fluids and the Asphalt Industry OEMs

Paratherm works together with the asphalt construction equipment OEMs to help their customers, and ours, to keep their systems maintained, up and running, especially when it counts the most.

It’s August, and in North America, the paving season is at its apex for 2016.

Among the equipment specialists in the asphalt-paving industry is Meeker Equipment Company Inc., which manufactures components to upgrade, renovate, and retrofit existing asphalt and ready-mix plants.

I spoke earlier this month with Jeff Meeker, President of Meeker Equipment, about this year’s paving season.

“We hear from our customers that generally speaking the paving season is going very well,” Meeker said. “Certain areas see a bit of trouble, usually related to political issues. New Jersey in particular needs attention to their transportation trust fund, so there’s a slowdown there at peak season.”

“We also see a lot of paving companies reinvesting in their asphalt plants,” Meeker emphasized. “Money that had been sitting on the sidelines is now going back into rebuilding their businesses.”

I asked Jeff for his opinion about of the evolving role of indirect heating, and specifically how the heat transfer fluids can be a key to preventive maintenance in the manufacturing process.

“Well, our people have become more plugged into talking to construction companies about their hot oil in these equipment discussions, and how important it can be for their operations,” Meeker explained.

“These days, when we visit our customers, our people always carry a heat-transfer-oil test kit,” Meeker said. “The plant managers and maintenance men are increasingly realizing the value of their hot-oil equipment, its impact and importance for their asphalt plants. So we can give them a test kit right there and get them started to evaluate the condition of the system based on the oil test results.”

If you’re an asphalt processor, and you’re interested in a fluid analysis kit, you can get one when the Meeker rep stops by. Or, here at Paratherm, there’s an online form you can fill out and we’ll send you one right away. Here’s the link: Fluid Analysis Kit.

and history of the PA Turnpike, its abandoned tunnels and planned modern renewal, and the engineering feat that took it through (not across)
Pennsylvania’s Appalachian Mountains.  Here it is— Ghost Tunnels of the Pennsylvania Turnpike.  Haunting photography, too.

A Stark Reminder of the Importance of Food Process Safety

A rather compelling reminder of the perils surrounding our food, our kitchens, and the entire journey of foodstuffs from field and barn to table and mealtime can be found nearly every day, while watching broadcast television.

In television production-studio kitchens, children as young as 8, and retirees in their 7th decade weave back and forth from the larders to their prep counters and pro-kitchen equipment, and from there to the ovens and stovetops, while competing to be selected as the best, by those persnickety and demanding celebrity chefs.

Vats of boiling oil, trays of broiling bacon, rotating mince blades, manual carrot chopping (fingernails in “claw” mode!), red-hot heating elements, grater surfaces, oven racks—these all can be focal points of danger and potential injury.

We watch as these intrepid and aspiring chefs, young and old, in the rush and turmoil of competing against both time and their highly skilled adversaries, inevitably back into each other while holding a hot vat or steaming kettle, or slice a digit or grate a fingertip or sear a knuckle, potentially dashing their hopes for the title of Master, Grand, or Top Chef.

On another channel in a fascinating recent documentary, about the early development of forensic science in New York City nearly a century ago, food contamination turns out to be the culprit in several very important court cases. For the first time in US history, meticulous testing and research were systematically used as legal evidence to prove accidental death, or intentional murder.

Summer Barbecue Safety Can Be Tricky

It’s the heart of the summer, August 2016. We put wine-soaked cedar planks on our gas grills for salmon seasoning, load piles of charcoal into our Webers and Hibachis, we marinate our proteins and brush EVO on our pepper slices and zucchini filets, we make wonderful food and the aromas of char and caramelization swirl through our neighborhoods; and we, too, must be wary of the dangers. I remember an afternoon 50 years ago when my dad had a stubborn batch of charcoal and was sprinkling some grill lighter fluid on the smoking briquettes. Suddenly the tin can exploded in his hand. It was startling, but fortunately no injury resulted. Perhaps slightly wounded pride in having to explain to your son how not to use lighter fluid, as amply demonstrated. Have you seen or used those stand-alone whole turkey fryers? Check it out on Youtube, and you’ll see more examples of people breaching safety procedures when cooking outdoors. Hint: Do Not Immerse a Frozen Whole Turkey into A Vat of Boiling Oil.

These days, food manufacturers, and restaurants and chains, are very meticulous with their processes to protect the safety of their products, and their customers. And their customers’ customers. Still, accidents happen.

Indirect heating with heat transfer fluids has been common in industrial manufacturing, including food processing, for several decades now.

In 1968, a heat transfer fluid made of PCB (since banned for functional heating purposes, as well as most other uses) poisoned more than 1600 people in Japan, due to accidental contamination of edible rice oil.

We’ve Come a Long Way Since 1968

Food-grade heat transfer fluids are now very widely used in food manufacturing equipment, including high volume fryers, ovens, grills, dryers, and distillation applications; in the poultry, meat, dairy, baking and vegetable-oil processing industries.

Food-grade heat transfer fluids assure the consumer public, and the food production industry, that these crucial steps of these food-manufacturing processes are properly engineered, safe, and reliable.

Food-grade heat transfer fluids were originally registered and certified in the late 1970s by the USFDA and the USDA. Now, these certifications are maintained and managed by the NSF.

No food-grade heat transfer fluid has been more researched and more certified for safety than the Paratherm™ NF heat transfer fluid. In addition to its original certifications from the USFDA, the USDA, Canada H&W, and New Zealand MAF, Organism Laboratory Bioassay; and its current NSF registration and kosher and Halal acceptance, it’s the only product on the market that has been the subject of research into its inherent safety and toxicity after being used in a working process heating system manufacturing food products for several years.

Paratherm NF Food-Grade Heat Transfer Fluid

In other words, not only has Paratherm NF held multiple certifications and passed toxicity standards as a brand-new, clear, unused fluid, it has also passed muster as a used, beaten up, moderately browned, yet still perfectly usable, still-within-specifications food-grade thermal oil.

We did these tests because no other food-grade fluid is used in more food plants and applications. Paratherm is the leader in this niche, in products, in service, in technical expertise, and we take the safety of the product very seriously, and intend to remain the leader.

So you can be assured, whether you’re specifying food-grade fluid for a new system, or have been using the same charge of fluid for 5 years, that it’s safe. Contamination aside, Paratherm NF continues to pass bioassay whether it’s new or used.

Paratherm also works with all its customers to maintain their systems, to test their fluids regularly, to avoid problems and prevent contamination as much as possible. Paratherm offers plenty of information on the web as well, to assist with safe handling and use of all of our products.

Paratherm has a section of its website that collects all these safety resources in a single place. View it at www.paratherm.com/safety

What Makes Paratherm Different

How does Paratherm differ? We drew the differences in a 2-minute video — whiteboard style!

And, for those of you who prefer to read, skim, study, and/or critique the written word, here is the voice-over script…

videofrontThe beauty of closed-loop hot-oil technology is that it operates simply and uniformly with little of the maintenance intervention required by alternatives like steam or direct heat. But this low-maintenance characteristic of the technology may leave you in the dark about the operating condition of your application, or what to do when shut down — or slowdown — occurs. Paratherm focuses on keeping you involved in every aspect of the care of your system, from the fluid sale and initial fill, to fluid analysis, troubleshooting and preventive maintenance. Paratherm’s experts will help advise you in the selection of the right fluid for your unique circumstances, and their professional fluid analysis will help guide preventive and predictive maintenance to help improve the system’s operation—and extend its operating life. Unplanned downtime with your application can cost you thousands of dollars every hour that you’re not in production. Therefore, Paratherm utilizes a streamlined logistics flow for fast supply when you need an expedited response. We keep our fluids in stock at several locations throughout the country. When you send us an order, we’re typically able to ship it the same day. When issues with your hot-oil system arise, Paratherm’s Technical Services section is ready with probing questions, and then, troubleshooting tips to help get it working again. You can reach someone by phone for technical assistance or an emergency shipment at any time, including evenings and weekends. At Paratherm, thermal fluid is all that we do, so we have to be the best. For more information on our products and services, simply call or visit our website and fill out our online form.”

Summer is System Maintenance Season

Summer means long, hot days, beach trips, barbecues, and plenty of celebrations. It also means days off and time away from work; at Paratherm, we often notice that this translates to downtime for our clients’ process-heating systems and a slow-down at their facilities.

Fluid Analysis Kit

When things do slow down, it’s a good time to focus on maintaining and improving your heating system; it’s also critical to your quality and safety. In fact, fire safety professional groups and insurers say that fluid analysis is considered a best maintenance practice, while the NFPA and Industrial Insurance underwriters suggest a minimum of annual testing.

One of the best ways to perform regular maintenance and testing is through a comprehensive analysis. Using our fluid analysis kit—which simply entails sending us a sample—we can determine any early warnings about process and equipment problems, and catch something before it becomes a bigger concern. The analysis tests both acid number and viscosity, and determines whether the fluid can remain in use, or needs to be replaced. It also analyzes the condition of the components of the system itself—another invaluable, time- and money-saving tool.

Hot Oil System Cleaner Dissolving Sludge

If you are having trouble keeping a process hot or getting the system up to running temperature, this could be an indication of fouling in the heater tubes. In this case, Paratherm liquid cleaner can be used to effectively dissolve deposits while the system is running, and will result in a cleaner, more reliable system.

Taking the short amount of time now to perform a fluid analysis and using the system cleaner will prove invaluable in the long run, ensuring safety and savings throughout the year. Then you can relax and enjoy those summer celebrations.

Paratherm Heads South For Both ILTA & NISTM Conferences

Next week kicks off Paratherm’s venturing to two events—both conferences with adjoined trade shows—within the storage tank and liquid terminal industry.

First up is the 2015 NISTM Conference & Tradeshow in Orlando, Florida. This non-profit base organization provides an opportunity for exhibitors and keynotes speakers, to network and learn about the industry’s operation innovations and regulations. It will cover a range of topics from management best practices to new AST operations and environmental topics.

NISTM logo

April 27 – 29 2015 Rosen Shingle Creek Hotel – Orlando Florida

Some topics we are looking forward to hearing about are best practices for transferring hazardous materials via rail or pipeline. Meeting and discovering all exhibitors with any new lining/coatings for storage tanks and innovative solutions for corrosion protection. As well as being updated on any changes on the NACE and API Corrosion Protection Reference Standards. An added reference we think will be helpful for those in attendance is the session reviewing what to expect from an AST Compliance inspection.

The conference also gives a glimpse of the new concerns and technology solutions that are coming onto the scene including robotic inspections, 3D laser scans, and top spill, fire, lightning responses and safety practices. We are excited to learn, participate, and see first hand all the latest innovations, standard changes, and new management strategies.
Be sure to look for us in booth 507!

June 1-3, 2015 – Houston, Texas George R. Brown Convention Center

After NISTM, we head over to Houston, Texas for the  ILTA International Liquid Terminals Association conference and tradeshow. This premier event is celebrating its 35th year, and we are happy to contribute towards making it a memorable year. With over forty speakers, thirty-one sessions and six workshops we are ready to contribute and gain many new insights and strategies.
ILTA has exhibitors and speakers from around the world so we know we will find the best solutions, latest equipment and engage in thought-provoking discussions throughout the three days.

We’re excited to gain and bring back with us some new ideas to use within Paratherm to continue to provide the best transfer fluid solutions possible.  If you are attending, be sure to visit us in booth 1001. We would love to connect with as many aligned thought leaders as possible.

New Paratherm™ HT Heat Transfer Fluid

Hydrogenated Terphenyl Chemistry Exhibits Durability,
High Temperature Capabilities

West Conshohocken, PA – USA – April 15, 2015

 

Paratherm recently introduced Paratherm HT Heat Transfer Fluid, which further expands the line’s temperature range for processing applications.  The product is formulated for closed-loop liquid-phase heating to 650°F in fired hot-oil heaters and 675°F in waste-heat recovery and full convection heaters used  in the  gas processing, plastic and chemical production , waste-oil recovery and biodiesel industries.  Clear Yellow Fluid Pouring Into Lipped Beaker

Jim Oetinger, Paratherm director of technology, saw the opportunity and need for the new fluid based on market research.  “Partially hydrogenated terphenyl based heat transfer fluids are nothing new; the chemistry is a proven performer. What our research told us is that there is a need for our core services – availability, fast shipment response and in-depth technical support – that is not being met by traditional suppliers.”

Founded in 1988, Paratherm has become a leading manufacturer of heat transfer fluids, system cleaners and other additive products. The firm offers a range of products (currently 10 fluids and three cleaners) covering temperatures from -148°F to +675°F. Paratherm serves a diverse number of industries including the chemical industry, food processing and plastics manufacturing.

Paratherm’s efforts have long been focused on their clients’ applications, systems and operations with expert assistance and quick turnaround being top priorities.  Orders can be filled quickly and in urgent situations very quickly, because the company stocks product in half-a-dozen North American locations and internationally in Europe, South America and Asia.

Since December 2012, Paratherm has been a business of CPI, a division of The Lubrizol Corporation.

The Easy Way to Sell More Fluid

The reason Paratherm, and other responsible heat-transfer fluid manufacturers, put so much value on fluid analysis is because it’s an objective and scientific evaluation.

Yes, there is a wide range of test values between brand-new fluid and fluid that has reached its end of life. And a discussion of the test results with a trusted expert allows the system operator to make informed choices in maintaining the equipment and the fluid itself.

But a useful tool like fluid analysis can be misused in some circumstances. Occasionally we hear about a competitor using hot-oil test results to sell to sell more fluid, in a questionable, even unethical, way.
 

“I’m Chris Hansen from Dateline NBC, and I Think You’re Lying to Me”

 
There’s a familiar formula for investigative television programming, routinely used on shows like 60 Minutes, Dateline, and 48 Hours, where the producers trick dishonest plumbers and car mechanics into revealing their sneak tactics for selling brand-new (but unneeded) water heaters and transmissions to the unwary.

Let’s face it, these television newsmagazine programs confirm an uncomfortable truth that we all would prefer not to believe; there are a lot of rats out there trying to rip us all off. Yes, there are good honest mechanics too, but if we’re to believe what happens on Dateline, you’ve got about a 50/50 chance of drawing a rat when you start a new relationship with a home contractor.
 

But what about industrial commerce?  Heat Transfer Fluid?  It can’t happen here, right?
 

Yes it can. Once a year or so, in fact, we hear about a customer being told to replace their total fluid volume when they don’t really have to. Sometimes it’s one of our customers, and sometimes it’s a case where we’re being asked for a second opinion.

In this blog, we try to keep our posts relatively short, so we’re not going to present a lot of detail here, but if you want the whole story with all the ugly details, give us a call.

And consider a rule of thumb; if two companies differ on an important sales recommendation, whether for fluid, equipment, or service, consider which one has the most to gain in the short-term, and evaluate accordingly.

And for that evaluation process, you don’t have to go it alone. Try thinking outside the box, or looking inside the box. These days there are online industry forums where people can ask questions and get answers; there may be competent, objective, and discerning pros on your own staff (or sister plants) that could weigh in; and there are seasoned, experienced engineers out there editing professional journals and running LinkedIn groups who would probably be happy to evaluate a real-life, real-time puzzler.

And one other thing… notice the single glaring circumstance all those televised scam examples seem to have in common; the victim in every case has no pre-existing relationship with the contractor scam artist.

Bottom line: Develop a network of suppliers and servicers that you can trust, and stay with them.
And if you think any supplier is trying to sell you something the easy way, slow it down. Ask questions. Make ‘em work for it.
 
Keep calm and I'm Chris Hanson from Dateline and I think you're lying to me

A Few Frequent Questions…With Answers

In Depth Answers to a few Frequently Asked Questions about Heat Transfer Fluids

Heat Transfer Fluid FAQ

 

The technology of heat transfer fluids is not extremely complicated. It involves liquids, heaters, pumps, flow rates, thermal and physical properties, and a few basic engineering principles.

Still, some of the more curious aspects of the fluids themselves fit with common-sense expectations, while at the same time, some other behaviors of these rascals fit into the non-intuitive category.

As one of the leading publishers of online content and information about the technology and use of heat transfer fluids in the process industries, we get a fair number of questions…

Questions that we are happy to help answer for you and questions that reach both ends of a very broad spectrum. That being said, we have found that there are just a few questions that we hear more than others. In an effort to help guide our customers to the best understanding possible of our products, we have put together a list of the top questions that we receive as well as providing our answers.

Here are three of them, in no particular order. In future blog postings, we’ll add to this list.

If we did not cover a question that you have, please call us! We would love to hear from you.

 

Q1.    If I can use water why would I want to use HTF?

A1. You probably wouldn’t. We often tell people that they’re better off with water, or water with freeze protection There are, however exceptions:

  • Once you get above 212°F, water boils and thus creates pressure in the system.  Get up to 400° and that pressure becomes substantial.  Non-aqueous heat transfer fluids don’t reach their boiling ranges until above 600°F.  High pressures (think steam) require different equipment, oversight, and maintenance practices for application and process management.
  • Water also freezes at 32°F.  Non-aqueous HTFs will remain liquid down to 0, -10, -35 and lower.
  • Water is also corrosive unless carefully treated and maintained. Not HTF.

 

Q2. What presentations do you offer?

A2. 5-gallon poly pails, 55-gallon steel drums, 1000-liter skidded totes, 330-gallon totes, and bulk by the gallon in trailer tankwagons or lined ocean 20- and 40-foot containers.

 

Q3.    Do you have local stock in Silverville?

A3. Paratherm has North American stock in Pennsylvania, Georgia, Arkansas, Indiana, Nevada, and Ontario.  Internationally, in Europe and with distributors in Brazil, Argentina, Mexico, China and Thailand. Not all products are stocked in all locations. Call for specific availability.


Q4.    Do you have a fluid for a) 800 degrees F?  b) 1200°F? c) -100°C?

A4. a) 800°F – We don’t but we know manufacturers that do. This is the limit for commonly used chemistries. Paratherm’s highest temperature product will withstand a film-temperature of 750°F

  1. b) 1200°F – Nobody does.  Rarely used molten salts have performed over 900°F, but they’re quite a challenge to handle and utilize.  We can recommend firms who provide these products, and engineer these systems.
  2. c) -100°C – Paratherm’s lowest goes to -88°C.  For lower temperatures, other technologies such as liquid nitrogen and helium are used.
