Title:

FLUE GAS TREATMENT SYSTEM WITH AMMONIA SOLVENT FOR CAPTURE OF CARBON DIOXIDE

Document Type and Number:

WIPO Patent Application WO/2013/144899

Kind Code:

A3

Abstract:

A system for treating a flue gas from a combustion process comprises an absorber vessel configured to receive an aqueous ammonia solvent stream lean in CO2 and a flue gas stream having CO2, the aqueous ammonia solvent stream and the flue gas stream in contact in the absorber vessel in a counter-current arrangement to provide an outlet stream rich in CO2; a desorber configured to strip the CO2 from the outlet stream rich in CO2 from the absorber vessel at a temperature less than 100 degrees C and to return the resultant aqueous ammonia solvent stream lean in CO2 to the absorber vessel; a source of heat configured to supply heat to the desorber; and a CO2 sequestration system for sequestering CO2 stripped by the desorber.
