Paul Wurth S.A. will be responsible for engineering and construction of a coke oven gas (COG) compression and injection system for Hüttenwerke Krupp Mannesmann’s (HKM) blast furnaces A and B.

The new injection system will complement the existing natural gas (NG) injection and pulverized coal injection (PCI) systems. The new COG injection system will provide up to 30,000 Nm3/hour of COG per blast furnace, while injection of mixed COG and NG will provide up to 60,000 Nm3/hour per blast furnace.

In addition to engineering and construction, Paul Wurth’s scope of supply will include two geared turbo-type compressors, a noise-insulated housing for the compressor station and all process piping for the supply of the COG up to the tuyeres.

Commissioning is expected to start in the fourth quarter of 2022.
