Abstract

A unit for removing CO2 from a syngas comprises means (3) to remove acid gas from a syngas containing CO, H2S and carbonyl sulphide (COS) to eliminate at least most of H<2>S, means (11) for heating purified syngas (9), a saturator (13) for moisturizing the heated syngas to produce heated and moisturized syngas, means for injecting steam (17) into the heated and moisturized syngas to form a mixture of steam and syngas, at least one shift reactor (17, 21) for subjecting the mixture (18) to water gas shift reaction means for cooling the shifted syngas to form cooled shifted syngas, an adsorption unit (31) for removing H2O and H2S from the cooled shifted syngas by adsorption in any order to produce dehydrated syngas, means for separating the dehydrated syngas (33) by partial condensation and/or distillation to form a H2 rich gaseous stream (51, 57) and CO2 rich liquid stream (44) and means for sending the H<2> rich gaseous stream as fuel to a gas turbine.
