'METHOD FOR REMOVING CO2 FROM EXHAUST GASES, SUCH AS EXHAUST GASES FROM PLANTS FOR PRODUCING RAW IRON OR EXHAUST GASES FROM SYNGAS PLANTS'

摘要

Method for removing CO2 from exhaust gases, such as exhaust gases from plants for producing raw iron or exhaust gases from syngas plants What is shown is a method for the removal of CO2 from exhaust gases (9), such as exhaust gases from plants for pig-iron production or exhaust gases from synthesis-gas plants, in which the CO2 is removed by means of chemical and/or physical absorption (14), the heat for regenerating the absorbent being obtained at least partially from an air separation plant (23). As a result, the CO2 can be separated from the exhaust gases to a greater extent than in the pressure-swing adsorption of other gases, but a lower-order energy carrier can additionally be used for this purpose.
