Enerfab, Croll-Reynolds to team in WESP supply to electric power industry

WESTFIELD, NJ, Dec. 17, 2002 — Enerfab and Croll-Reynolds Clean Air Technologies announced a licensing agreement for Croll-Reynolds’ wet electrostatic precipitator technology for the power generation industry.

Enerfab, founded in 1901, is a privately held diversified provider of design engineering, fabricated steel products, field construction and maintenance services for both industrial and utility markets. Croll-Reynolds, founded in 1917, is a privately held supplier of air pollution control equipment to industrial and government facilities.

Electric utilities that burn fossil fuels such as coal or oil to generate steam, create combustion by-products that are hazardous air pollutants. These pollutants include nitric oxides, sulfur oxides, mercury and other toxic chemicals, as well as particulate matter. Current Federal regulations limit the amount of particulate matter under 10 microns in size, (PM10), and sulfur dioxide (SO2) that can be emitted from a plant.

State regulations limit visible smoke from a power plant’s stack. Future federal and state regulations will also require control of fine particulate matter under 2.5 microns in size, mercury and sulfur trioxide, the primary contributors to creating visible smoke from a stack.

Wet electrostatic precipitation (WESP) is recognized control technology for the WESP technology smallest and hardest to capture particles, under 1 micron in size. It has been used for decades in the sulfuric acid industry for control of sulfuric acid mist, a 0.3-micron size particle. Coal-fired power plants will need this technology as a final polishing device to meet future regulations and reduce visible smoke.

The licensing agreement will give Enerfab rights to market, sell, manufacture and install Croll- Reynolds’ WESP technology for fossil fuel power plant applications. Croll-Reynolds will provide technical and process engineering support to Enerfab.
