Syngas for blast furnace decarbonization
Launching the production of syngas, SMS group company Paul Wurth has put into commission a pilot coke oven gas dry reforming plant in Dillingen at ROGESA Roheisengesellschaft Saar mbH.
Paul Wurth has successfully started a pilot plant in Dillingen, Germany at ROGESA Roheisengesellschaft Saar mbH for testing the dry reforming process of coke oven gas with blast furnace gas. This is an important milestone in the development of dry reforming technology and the generation of syngas. The process involves producing syngas using a high temperature catalyst-free reforming process. The first months of operation have proven the feasibility of the process, with excellent conversion ratios of up to 98%. The syngas produced by Paul Wurth's dry reforming process has the optimum composition and temperature for a versatile use as reducing gas in the BF process, significantly surpassing the syngas quality produced by traditional catalytic reforming processes. The quality and high temperature of the reducing gas not only allow the utilization at shaft level but also at tuyere level.
The aim of this development is to maximise the reutilization of steelmaking process gases, namely blast furnace and coke oven gas in the steel production process. The end goal is to lessen the use of coking coal.
