Abstract (en)
[origin: EP2762220A1] The method involves reducing a carbon dioxide-portion in lean gas and/or exchanging gas portions in the lean gas against oxygen in a membrane separation unit (1). A retentate is subsequently utilized in an utilization unit, which is provided downstream to the membrane separation unit on a retentate side. A permeate of the membrane separation unit is mixed to hot exhaust gas of the utilization unit, and reoxidized. A partial pressure difference between the permeate and the retentate in the membrane separation unit is increased by pressurization of feed gas. An independent claim is also included for a device for performing a method for utilization of lean gas.
