Users design safety instrumented systems to bring the risk of identified process hazards to within tolerable levels, using application-specific risk models, user inspection schedules, and safety data for the devices under consideration. A key problem when designing such systems is…
Researchers from Newcastle University (U.K.; www.ncl.ac.uk) have discovered that, in the presence of a nickel catalyst, CO2 can be rapidly and cheaply converted into solid carbonate salts. The discovery could lead to a simpler and less-expensive alternative for carbon capture…
An ultraviolet oxidation process for the destruction of water-borne organic contaminants that combines UV with chlorine, rather than hydrogen peroxide, is being developed by MIOX Corp. (Albuquerque, N.M.; www.miox.com). The company’s Advanced Oxidation Process (AOP) promises to be less expensive…
This company has released the rectangular version of its popular CV-S Explosion vent. Specifically designed to provide non-fragmenting opening when protection industrial process equipment, the CV-S explosion vent is said to provide superior protection in applications such as air-material separation,…
One of the most unsettling experiences in a company’s existence may be the surprise regulatory inspection by a representative of the U.S. Environmental Protection Agency (EPA) or a State Environmental Agency. What if you refuse to let them in? What…
