Minimize emissions from semiconductor facilities

Article Abstract:

Prevention of microcontamination, health and safety maintenance and environmental compliance at microelectronics or semiconductor manufacturing plants rely strongly, in part, on the design and selection of both exhaust conditioners and centralized air abatements systems. A comprehensive approach on the management of process exhaust gases emitted from microelectronics production machinery and facilities has been developed. This approach may help engineers to better understand process exhaust systems and minimize air flow rates and emissions.

Plasma arc boosts sludge treatment

Article Abstract:

Hydro-Quebec has developed a sludge treatment process for pulp and paper mills using an atmospheric-pressure rotary furnace operating at about 600 degrees centigrade. The plasma-assisted oxidation process uses a low- power, plasma-arc torch, which generates ultraviolet radiation and highly chemically active ionic and radical compounds that catalyze the cracking and oxidation reactions. The process consumes less than 100 kWh/tonne of moist sludge.

Landfill gas to power auto assembly plants

Article Abstract:

Auburn Hills, MI-based DaimlerChrysler Corp will use waste gases from decomposed landfill wastes to provide power to its two automobile assembly plants in St Louis, MO. To achieve this, two of the four powerhouse boilers have been modified to use landfill gas to produce steam in a similar way with the use natural gas boilers. The project is due to commence in late 2000.
