    Recent graduates with engineering degrees typically have very little – if any – experience with thermal insulation. This knowledge gap can now be bridged with ASTM C1696, a guide designed to provide the specific knowledge required for the development of a thermal insulation system within a large-scale engineering project.more...

    Industrial insulation, whether it’s mineral fiber, perlite or calcium silicate, is often considered a necessary evil during the industrial process design phase – a required add-on that has to be factored into the project estimate. Calculating the thickness of that insulation is typically done by balancing the twin goals of minimizing installed cost while conforming to safety requirements.more...

    The Marcellus-Utica shale gas boom underway in Western Pennsylvania has created new prospects for downstream petrochemical operations, as various multinational manufacturers assess how to capitalize on the region’s suddenly abundant, inexpensive energy source. Now comes word that two Brazilian energy giants are considering an olefin cracking facility and three polyethylene manufacturing plants in West Virginia that would tap the pipeline networks now beginning to take shape in the region.more...
