The company ENVIROTHERM Technologies for the removal of nitrogen oxides, for deducting and desulphurization of flue gases from power stations today make a significant contribution to air quality control and thus to the environmental compatibility of fossil-fired power stations. Envirotherm – founded in 2001 as successor of the Lurgi Engineering GmbH at the Ruhr – have specialized in the development and construction of plants for purifying flue gases, waste incineration plants and boilers . With a highly qualified workforce of around 80 at company headquarters in Essen, Germany, with representatives in the growth markets of Southeast Asia and North America an and excellent reference list, Envirotherm is one of the most competent business partners worldwide. The well known wet flue gas desulphurization processes, developed by sister company- Enviroserv GmbH, are based on using lime/limestone, seawater or ammonia as reagent and have been installed in power stations with a total
