Improved environmental protection through modern coke plant technology at the new plant in Schwelgern

The new coking plant Schwelgern is going to be erected by the Carbonaria Gm bH on a spit of the works port to replace the coking plant August Thyssen i n Duisburg-Bruckhausen. The coking plant Schwelgern will be equipped with t he most modern techniques also concerning the environmental protection. The plant consists of two batteries, each equipped with 70 coke ovens with a c apacity of 93 m(3) per oven. The scale up of these biggest coke ovens in th e world is caused by cautious increase of the chamber height to 8.43 m and chamber length to 20.80 m. Lowering the amount of pushing coke ovens from 5 60 per day in the coking plant August Thyssen to 135 per day in Schwelgern causes a high reduction of pollution. Further improvements are realized by the use of computerized process control of coke oven batteries and gas puri fication. The pressure control of individual coke ovens, possible by using PROven (pressure regulated oven), is also responsible for lowering of pollu tion, proofed by scientific data. The use of new scaling systems at ascensi on pipes, further developments of the coke oven doors and the residual free combustion of coke gas by steam injected crude gas torches improve the env ironmental situation, too. The cornerstone ceremony happened on the 26 July, 2000. In spring 2003 the first coke will be pushed.
