Schwelgern coking plant
The Schwelgern coking plant in Duisburg is one of the most modern and largest coking plants in the world.
The builder and owner is Carbonaria Beteiligungsgesellschaft mbH & Co., in which Commerz Real Asset Verwaltungsgesellschaft mbH and Hannover Leasing GmbH & Co. KG hold shares. It is operated by the ThyssenKrupp operating company KBS Kokereibetriebsgesellschaft Schwelgern GmbH, which employs 309 people from the previous August Thyssen coking plant (Operations Director Klaus Hofherr ). The main purchaser of the coke produced here is the neighboring ThyssenKrupp steelworks Schwelgern .

The coke wet cooling takes place in the newly developed " CSQ process " (Coke Stabilizing Quenching), which is supposed to reduce the dust pollution below the permissible value for coke wet cooling of 50 mg / t coke. The cooled coke is transported to the coke screening plant via conveyor belts . In the coke screening plant, the coke is sorted by size and transported on to the TKS-Schwelgern blast furnace via belts or wagons .
With a newly developed complex process, ammonium hydrogen carbonate is created from washed coke oven gas by adding carbon dioxide , which then serves as a starting material for the production of nitrogen fertilizers and foaming agents for plastics and porous ceramics . This process will be tested in a new pilot plant in 2016.
Specialty
In contrast to old industrial buildings, this coking plant was designed according to a color concept by the color philosopher Friedrich-Ernst von Garnier . There are light green tones with accents of blue and yellow. These colors have optically integrated the industrial giant into the river landscape.
Emissions
The pollutant emissions of all large industrial companies and power plants are published in the European Pollutant Emissions Register (via the German portal Thru.de).
Emissions below the reportable quantity threshold are listed in the table with "<" next to the limit value.
