Does lab testing tell the whole story? There are a number of accelerated aging laboratory tests that are designed to determine oxidation-inhibitor performance and longevity. Most involve bubbling pure oxygen through a heated sample that has an oxidation catalyst (usually copper wire) submerged in it. The effectiveness of the additive is determined by measuring the [...]

Fluid Life Tests While oxidation is the #1 reason that heat transfer fluids need to be replaced, it doesn’t always follow that using a fluid with an oxidation inhibitor will prevent oxidative sludging. Oxidation inhibitors are chemical additives designed to prevent the sludge formation, acidification, and viscosity increases that result when air and hot [...]

Why aren’t there any trade publications formatted for e-reader tablets such as the Nook, Kindle, Kobo, Iriver, Sony? I’ve asked several publishers of magazines in the processing sector, magazines covering the chemical industry and related vertical sectors if they are planning portable versions of their publications. Sometimes they look at me funny, or if we’re [...]

Insulation is nothing more than a large number of air pockets that are held in place by some type of material. For high-temperature systems pumping combustible liquids, these materials may consist of mineral fibers, compressed particles (calcium silicate or perlite) or cellular glass.

When designing or maintaining a hot-oil system, one important aspect is thermal insulation; adequate insulation is a necessary evil on these systems. Even if energy costs were zero, there would still be the need to protect company personnel (especially overzealous young process engineers and nosy visitors from headquarters) from exposure to hot pipes. Not to [...]

Paratherm Corporation is exhibiting at two industrial trade shows this month.
First, on October 13, is the Alternative and Renewable Energy event, a virtual conference and trade show on the ON24 online event platform, presented by Globalspec.
Also in October, on the 19th through the 21st, in Houston, Texas, Paratherm will be exhibiting live at the ChemInnovations Conference and Expo.

I arrived at the trade show a few minutes after the doors opened; there was a fellow out in the lobby area talking generalities to early arrivals like me. I decided to skip the pep talk and went straight into the exhibit hall. First I meandered down a couple rows, browsing the booths without stopping in anywhere. Most [...]
