Kisuma Chemicals helps reduce CO2 emissions from Iron & Steel production
Veendam, June 27, 2015
Kisuma Chemicals is one of 9 participants in a project that was recently granted 13 million Euros by the EU's Horizon 2020 research program. The aim of the consortium behind STEPWISE, which is short for ''SEWGS Technology Platform for cost effective CO2 reduction in the Iron & Steel Industry'', is to convert blast furnace gas into carbon dioxide and a high grade fuel. This project marks the next step in the development of the SEWGS technology (Sorption Enhanced Water Gas Shift), which will be demonstrated in a pilot plant which will be constructed at Swerea MEFOS in Luleå, Sweden. Blast furnace gas from steel producer SSAB will be fed at high pressure and high temperature to the pilot unit. There, the blast furnace gas is converted by a water gas shift process into carbon dioxide and a high grade fuel, consisting of hydrogen and nitrogen. The CO2 is captured and can be sequestered while the fuel stream can be used to generate energy in a combined cycle, or to enhance steel production elsewhere in the Steel and Iron plant.
A vital part of the SEWGS technology is a sorbent that will be produced and supplied by Kisuma Chemicals. The sorbent is based on a special hydrotalcite-like precursor material and has so far proven to be extraordinarily effective in adsorption and desorption of CO2. Since the start of the co-operation between ECN and Kisuma Chemicals in 2011, new sorbent developments have resulted in significant efficiency increases of the SEWGS technology. Kisuma Chemicals expects that the suitability of their sorbent will be proven on a larger scale and hopes this will open up new spin-off applications.
The STEPWISE project has started in May 2015 and will run for four years. The project has the potential to decrease CO2 emissions in the Iron and Steel industry worldwide by 2.1Gt/yr based on today's emission levels. The other consortium partners are ECN (coordinator), Johnson Matthey, SSAB, Tata Steel UK Consulting, Amec Foster Weeler, Swerea MEFOS, Polytechnic University of Milan and Babeș-Bolyai University.
