Abstract
A method for revamping a CO2 removal section for removing carbon dioxide from a hydrogen-containing synthesis gas, wherein the CO2 removal section comprises an absorption section () wherein carbon dioxide is transferred to an absorbing solution and a stripping tower () for regeneration of the CO2-loaded solution, said stripping tower comprising an upper zone () where a first gaseous CO2 stream () and a partially regenerated semi-lean solution () are produced, and a lower zone () acting as a stripping zone where a second gaseous CO2 stream () and a lean regenerated solution are produced, the second CO2 stream () being a substantially pure stream containing less hydrogen and impurities than the first CO2 stream, and wherein the method of revamping provides the installation of sealing means () inside the stripping tower (), arranged to isolate said second gaseous CO2 stream () from the first stream (), so that the second stream () can be exported separately.
