Abstract
A process for removal of HS and COfrom an acid gas stream comprising HS and CO, the process comprising the steps of: (a) reacting HS in the acid gas stream with SOto form sulphur vapor and water vapor, thereby obtaining a first off-gas stream comprising CO, water vapor, sulphur vapor, residual SOand residual HS; (b) converting residual SOin the first off-gas stream to HS in a first off-gas treating reactor, thereby obtaining a second off-gas stream depleted in SOand enriched in HS and COcompared to the first off-gas stream; (c) contacting the second off-gas stream with an HS absorbing liquid, thereby transferring HS from the gas stream to the HS absorbing liquid to obtain HS absorbing liquid enriched in HS and a third off-gas stream enriched in CO; (d) removing COfrom the third off-gas stream by contacting the third off-gas stream with COabsorbing liquid in a COabsorber, thereby transferring COfrom the third off-gas stream to the COabsorbing liquid to obtain COabsorbing liquid enriched in COand purified gas.
