Patent ID: 8529854

Claim:
A process for removal of carbon dioxide from a feed gas comprising the steps of: a. feeding a feed gas and a recycled absorbing agent containing carbon dioxide to a stripper column, b. stripping said recycled absorbing agent containing carbon dioxide with the feed gas and thereby obtaining a gas having a higher concentration of carbon dioxide than the feed gas and a liquid of absorbing agent comprising small amounts of carbon dioxide, c. cooling the gas obtained in step b, d. separating the cooled gas obtained in step c into a carbon dioxide rich liquid and a carbon dioxide containing gas, e. cooling the liquid of absorbing agent obtained in step b, f. absorbing carbon dioxide from the carbon-dioxide containing gas obtained in step d with the absorbing agent obtained in step e, by which the carbon-dioxide containing gas is separated into a carbon-dioxide depleted gas which may be disposed of, and a liquid of absorbing agent containing carbon dioxide, and g. increasing the temperature and/or reducing the pressure of the liquid obtained in step f before recycling it to the stripper column.
