Process hazards analyses (PHAs) are structured reviews during the engineering design process intended to detect potential hazards that were not addressed by the design team. This one-page reference describes commonly employed PHA methods. PHA methods PHAs are often conducted or…
Allyl chloride (3-chloropropene; Figure 1) is primarily used almost exclusively as a chemical intermediate in the production of epichlorohydrin. A three-carbon epoxide, epichlorohydrin is used in the manufacture of epoxy resins prevalent in coatings, adhesives, and plastics. Epichlorohydrin is also…
Presented here are some practical points to help in the selection of a shell-and-tube heat-exchanger design for various applications Heat exchangers are widely used in various sectors of the chemical process industries (CPI), including: chemical; oil and gas; power generation;…
Light hydrocarbons in storage tanks can vaporize and vent to the atmosphere, creating harmful emissions. An optimized vapor-recovery unit can effectively and economically reduce such emissions In the chemicals, petroleum refining and natural gas industries, storage vessels are used to…
