Hydrogen cyanide (HCN) is a chemical precursor used in the production of several industrially relevant compounds, such as adiponitrile for nylon production, methyl methacrylate for polymer manufacturing, sodium cyanide for gold recovery and for the production of methionine, which is…
What are the steps to finding the best pressure sensor for a particular application? That’s a challenge faced by many a young engineer just out of school. Engineering school teaches a great deal of theory, but what is the best…
Gaskets are relatively simple pieces of equipment in principle, yet are entirely critical in many types of chemical process industries (CPI) applications, including pipes and vessels. An understanding of gasket function, and of the forces and stresses acting on gaskets…
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…
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…
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…
