In recent years, a number of factors have further emphasized the importance of solvent selection in the chemical process industries (CPI). These include the increasing regulatory scrutiny leveled on industrial solvents, and an effort by CPI companies to reduce the environmental, health and safety (EHS) impact of their solvent use. In addition, specialized, high-performance solvents are available for some...

Much attention over the past two years has been focused on alternative energy and green chemistry. So it is particularly appropriate that Chemical Engineering’s (CE) 2010 Personal Achievement Award recognizes two individuals with expertise in those fields. Last month, at an award ceremony held at the ChemInnovations Conference and Exhibition in Houston, Tom McGowan, a longtime consultant in biomass...

The solubility of water in the hydrocarbons that comprise crude oil is an increasingly important issue in view of processing, safety and environmental considerations surrounding product quality and equipment sustainability. Water in the reacting hydrocarbon species may result in the formation of undesirable by-products. The presence of water in the product may be detrimental to quality. Water content at...

Many reactions, extractions, separations and other operations in the chemical process industries (CPI) involve the use of organic solvents. In addition to handling and disposal issues, organic solvents can pose a number of environmental concerns, such as atmospheric and land toxicity. In many cases, conventional organic solvents are regulated as volatile organic compounds (VOCs). In addition, certain...

  Although ammonia is still made by the near-century-old Haber-Bosch process, today’s ammonia plants bear little resemblance to those early units — now literally decorating the lawns outside BASF in Ludwigshafen, and Dechema in Frankfurt, Germany. For one thing, the efficiencies of this energy-intensive, brute-force reaction of hydrogen and nitrogen have increased dramatically, especially...
