Abstract

A process for providing a carbon monoxide-containing stream involves a separation of synthesis gas into a hydrogen-rich gas stream and a carbon monoxide-rich gas stream containing carbon monoxide to an extent of 85% by volume or more. The separation is effected in an arrangement composed of three membrane separation stages. Prior to the performance of the membrane separation, the synthesis gas is pretreated for removal of secondary components present in the synthesis gas.
