Industrial Insulation Systems: Material Selection Factors

Thermal insulation systems can provide several functions on piping and equipment in industrial facilities. Some of these are: reduction in energy loss, process control, personnel protection, emissions reduction, condensation, freeze protection, and noise reduction. In the chemical process industries (CPI),…

Fractionation Column: Pushing capacity limits

Starting around 1970, many new contacting devices became available for use in distillation, absorption and stripping columns. Those devices included high-performance random packings, structured packings, high-capacity structured packings, augmented crossflow trays, counterflow trays and cocurrent flow trays. At the request…

Recover Waste Heat From Fluegas

Adding an organic Rankine cycle system to generate power onsite can help operators optimize the overall economics of combustion-related systems and emissions controls The ever-increasing cost of fuel and relentless push for environmental responsibility are constant factors in the profitability…
