Valves and actuators designed for handling radioactive waste must meet strict government requirements. This sometimes requires unconventional solutions. Such was the case at the Hanford Waste Treatment Project (WTP), Hanford, Wash.
Guidance for chemical manufacturers, processors, and distributors about Section 8(e) of the Toxic Substances control act was issued on September 14, by the U.S. Environmental Protection Agency (EPA). Chemical Processing's Regulatory Editor Lynn Bergeson discusses the new regulation.
Theres more to boiler level control than measuring level and adjusting a feedwater valve. Improved measurements and inverse response are just a few of the influences on operating boilers in a reliable manner.
The compressed air industry is taking a step that will clear the air about the performance of its equipment. For the first time, many compressed air equipment manufacturers will submit their 50 hp to 200 hp lubricated rotary-screw compressors and 200 cfm to 1,000 cfm refrigerated air dryers to an independent laboratory for performance testing.
The new market realities of higher and rising energy costs as well as global pressures to reduce fossil fuel intensity have made energy management tracking much more valuable. Learn how to keep energy productivity programs from running out of gas in Peter Garforth's latest Energy Expert column.
While fermentation-based syntheses were once reserved for producing high-value specialty chemicals and biopharmaceuticals, bioprocess routes now are gaining increasing attention for commodity products.

The Restrictions of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (the RoHS Directive) is part of a growing wave of European Union product-based regulations that will profoundly impact global and United States product standards and thus the chemical industry.
Because many environmental applications of nanotechnology will almost certainly revolutionize the science, law, and regulation of water pollution, readers are urged to keep abreast of this fast-changing area.
"Bad actor" pumps are those pumps that have trouble with frequent and repetitive failures. In many cases, the source of the problem is an ANSI pump trying valiantly to handle a liquid well beyond the range of its design rating.of 300 degs. F.
