Modular bioreactor is proven for oily refinery waste

Article Abstract:

Petrozyme Technologies Inc.'s biological reactor is proven effective to use in oily refinery waste. The Guelph, Ontario, Canada-based firm's modular reactor is curing 15,000 tons/yr of oily slugde at Venezuela's buiggest refinery, managed by Petroelos de Venezuela S.A., in Cardon. Aside from successfully promotiming conversion of waste oil and sludge to water and carbon dioxide, the bioreactor, which uses advanced fermentation techniques, also offer lower treament costs than other alternative nmethods, including thermal desorption, incineration and feeding ther waste to a cement kiln.

Hot-gas filtration technology may be demonstrated in China

Article Abstract:

Westinghouse Electric Corp.'s Science and Technology Center (STC) in Pittsburgh, PA, is negotiating to conduct a field demonstration of its new moving, granular-bed filter system in China. STC's recently developed filter system functions at temperatures ranging from 800 to 1000 degrees centigrade and pressure ranging from 15 to 20 atm to purify syngas from coal-gasification plants. The new system, which is claimed to remove 99% of dust particles using sorbents fed to the hot gas into a vertical pipe or standpeg, could in effect reduce operational and maintenance cost.

A new process renders PCBs harmless without generating HCl

Article Abstract:

Mitsubishi Heavy Industries Co. Ltd. of Tokyo, Japan, has developed a new process for decomposing polychlorinated biphenyls (PCBs) into harmless salt and carbon dioxide. The new process uses steam that is superheated at 380 degrees Celsius and unlike supercritical water oxidation (SCWO), another treatment for PCBs, does not generate hydrochloric acid byproducts, eliminating the need for reactors made of corrosion-resistant alloys. Mitsubishi, which is currently using a 2-kg-per-hour plant, intends to make a commercial version available by April 1999.
