To ensure the health and safety of workers, the U.S. Occupational Safety and Health Administration (OSHA) adopted the Hazard Communication Standard (HCS) in 1983. Initially designed to protect workers in the manufacturing sector, the HCS was expanded in 1987 to…
Technology to copolymerize carbon dioxide and propylene oxide (PO) was first discovered in 1960s, but has not been commercialized due to the formation of cyclic propylene carbonate (CPC) by a “back-biting” reaction, which leads to the formation of unstable, low-molecular-weight…
Within five years, four large power plants in Europe will be outfitted — for testing at the pilot scale — with energy-efficient CO2-filtering membranes that are being developed at the Norwegian University of Science and Technology (NTNU; Trondheim; edlinks.chemengonline.com/6901-531). Professor…
A plasma-based waste-treatment process will be installed in Dow Corning Corp.’s silicon-products-manufacturing plant in Midland, Mich., where it will recycle chemical wastes, help lower the site’s consumption of natural gas by 400-billion Btu/yr and help reduce the plant’s total emissions…

Late last week, the U.S. Department of Homeland Security released Appendix A of the Chemical Facility Anti-Terrorism Standards (CFATS), a critical element of its chemical security efforts. The appendix contains a list of chemicals that, if possessed by a facility…
While the Pennant ECS can be put to multiple applications, multi-bagger benefits accrue with its ability to convert both saturated and superheated steam into clean electrical energy. Typically, the ECS is used in parallel with a Pressure Reducing Valve (PRV)…
Daicel Chemical Industries Ltd. (Osaka, Japan; edlinks.chemengonline.com/6900-540) is further developing an oxidation catalyst based on N-hydroxyphthalimide (NHPI), which was first discovered by Professor Yasutaka Ishii of Kansai University several years ago (CE, September 2000, p. 23). The catalyst, together…
