Abstract (en)

[origin: WO2015105438A1] Apparatus, where a water scrubber unit (20), mainly consisting of an absorption column (21), flash column (22) and desorption column (23) is integrated with a membrane unit (10), for purification/separation/enrichment of a gas or biogas containing significant amount of methane and carbon dioxide, wherein the carbon dioxide concentration of the gas is to be reduced, where an incoming gas stream (1) is merged with flash gas stream (24) from flash column (22) and pressurized in compressor (30) and then led into a membrane unit (10) for separation of carbon dioxide in a membrane (11), if necessary separation of water or heating in separation unit for water (12), separation of hydrogen sulfide in the separation unit for hydrogen sulfide (13) and separation of particles and other contaminants in the separation unit for particles and other contaminants (14), whereby a residue gas stream (3) departs and the purified gas stream (4) is led to water scrubber unit (20), wherein the energy for cooling and pumping of the recirculating water flow through the columns (21, 22 and 23) drops, alternatively, that the capacity for the production of upgraded biogas (5) increases.
