Lodge Cottrell Ltd. is a supplier of environmental air pollution control equipment for the power generation industry and other industrial process applications, with over 4,500 installations world-wide. It has facilities in Birmingham, England and Houston, Texas, United States, and operates through a network of associates, partners, agents and licencees. Lodge Cottrell Ltd and Lodge Cottrell Inc. are part of KC Cottrell Co., Ltd., an air pollution control company with its headquarters in Seoul, South Korea.
History
[edit]In 1883 Sir Oliver Lodge first demonstrated the use of electrostatic precipitation for the collection of dust particles. In 1886 the first attempt on a commercial scale to precipitate dust and fume from gas was made by Oliver Lodge and Mr A. O. Walker at Deeside Lead Works, Chester. In 1913 the Lodge Fume Deposit Company Limited was formed. Its offices were in Great Charles Street, Birmingham, England. Work began in 1914 at the Skinningrove Iron Company on the first electrical precipitator in the world to clean blast furnace gas. In 1919 the Lodge Fume Deposit Company was replaced by the Lodge Fume Company Limited.
Oliver Lodge's operations were admired by Dr. Cottrell of the United States, and an agreement was reached with the International Precipitation Corporation of California, USA, for full interchange of information and patents. In recognition of Dr. Cottrell's contribution to electrical precipitation, the Lodge Fume Company decided to change its name to Lodge-Cottrell Ltd.
Continued expansion necessitated larger premises and, in 1929, the company moved to its present location at George Street, Birmingham.
In the early 1990's Lodge-Cottrell acquired the gas cleaning activities of the Peabody Sturtevant and Peabody Holmes companies and the 3 operations merged to form Lodge Sturtevant Limited. In 1994 Lodge Sturtevant Limited was acquired by FLS Miljø a/s of Copenhagen, Denmark, part of the FLS Industries Group. In 1998 the business of EAF, acquired in 1992 by FLS Miljø, was merged with Lodge Sturtevant. In 2003 the Lodge Sturtevant business became a subsidiary of F.L.Smidth Airtech. In 2005 Lodge Sturtevant Ltd was acquired by Korea Cottrell Co., Ltd. In 2007 Korea Cottrell became KC Cottrell Co., Ltd. and the name Lodge Sturtevant was changed to its original 1922 name of Lodge Cottrell.
Technologies
[edit]Particulate Control
[edit]Lodge Cottrell supplies L-type dry electrostatic precipitators to reduce dust emissions, fabric filters for dust collection, and ceramic filters to control emmissions and reclaim materials such as metals and minerals, operating at temperatures of up to 500 °C (930 °F).
Flue gas desulphurisation
[edit]Lodge Cottrell Ltd provides FGD technology for large process applications such as power stations, steel works, and chemical plants. This is a limestone to gypsum process.
De-NOx Systems
[edit]De-NOx systems reduce harmful nitrous oxide gases. Lodge Cottrell provides catalytic (SCR) and none catalytic (SNCR) reduction systems.
Acid Gas Removal
[edit]When used in conjunction with a sodium or calcium based sorbent injection system, pulse-jet filters can also be used to reduce acid gas emissions. This is used in many energy-from-waste and incineration processes where the lowest emissions of sulphur oxides, hydrogen chloride and hydrogen fluoride are required. Other contaminants such as heavy metals and organic species can be removed through the addition of alternative types of sorbents. For some processes dry sorbent injection is not suitable. Where this arises a wet scrubbing system can be applied for the removal of gaseous pollutants.
