Pressure transmitters are widely used throughout the chemical process industries (CPI). Although pressure in and of itself is an important process parameter, differential pressure (DP) measurements enable the inference of other important parameters as well. This article presents a concise…
Reactive chemicals and intermediates are used extensively in the chemical process industries (CPI). Hazardous chemical reactivity can be defined as “any chemical reaction with the potential to exhibit rates of increase in temperature and/or pressure too high to be absorbed…
From plastics and synthetics to fertilizers and fuel, the general public takes for granted so much of what the chemical process industries (CPI) produces, and the risks associated with CPI production facilities are not typically considered. That is, until the…
Operators and engineers in the chemical process industries (CPI) who are responsible for the daily operations associated with sludge dewatering and drying equipment are undoubtedly aware that wastewater-sludge drying is not an easy task. A large number of the problems…
The compound 1,4-butanediol (BDO) is a versatile intermediate for the chemical industry. Its largest derivative product is tetrahydrofuran (THF), which is used to make spandex fibers, resins, solvents and printing inks. The second largest product is polybutylene terephthalate (PBT), which…
Magnetically driven (mag drive) centrifugal pumps have been in use since 1947 when the first magdrive pump was developed. Mag drives have always been the workhorse pump in applications with corrosive and often toxic fluid applications, and particularly over the…
Collecting representative samples of heat-transfer fluid for routine quality checks falls short of the goal if safety or the environment is compromised. While users should consider their systems’ unique design features in consultation with their safety and health experts, incorporating…
Hayward Flow Control Thermoplastic butterfly valve enables many stopping positions With its advanced, one-piece thermoplastic design and construction, the patent-pending BYV Series Butterfly Valve offers a variety of design advances, including a hand lever that features a 72-spline interlock mechanism…
Second only to electric motors, centrifugal pumps are the most common machine used in the chemical process industries (CPI). Pumps are serving in every conceivable fluid application. They move all manner of fluids from wastewater to paper pulp, from ultra-clean…
Sorbent materials are used commercially for bulk separation, as well as purification of both liquids and gases. This one-page reference provides manufacturing and application information on the most widely used industrial sorbent material — activated carbon. Four types of generic…
