Title:
PROCESS FOR THE REMOVAL OF CARBON DIOXIDE AND/OR HYDROGEN SULPHIDE FROM A GAS
Document Type and Number:
WIPO Patent Application WO/2010/146167
Kind Code:
A3
Abstract:
A process for the removal of CO2 and/or H2S from a gas comprising CO2 and/or H2S, the process comprising the steps of : (a) contacting the gas (102) in an absorber (104) with an absorbing solution (131) wherein the absorbing solution absorbs at least part of the CO2 and/or H2S in the gas, to produce CO2 and/or H2S lean gas (106) and a CO2 and/or H2S rich absorbing solution (108); (b) heating at least part of the C02 and/or H2S rich absorbing solution to produce a heated CO2 and/or H2S rich absorbing solution (122); (c) removing at least part of the C02 and/or H2S from the heated CO2 and/or H2S rich absorbing solution in a regenerator (124) to produce a CO2 and/or H2S rich gas (129) and a C02 and/or H2S lean absorbing solution (130); wherein the least part of the heat for heating the CO2 and/or H2S rich absorbing solution in step b) is obtained in a sequence of multiple heat exchangers (140, 142, 144).
