Process and apparatus for the production of carbon monoxide

摘要

The feed gas is sent to a pressure modulation adsorber (2) which contains an adsorber with a low affinity for hydrogen and carbon monoxide (CO) and a strong affinity for the other components. The gas from this adsorber is sent to a purifier (3) using permeation provided with membranes which strongly select between CO and hydrogen, producing a stream of pure CO. An Independent claim is also included for apparatus for carrying out the above process, with a PSA (pressure swing adsorber) (2) and a purifier (3).
