I am looking for a cryogenic process to separate high purity CO (Carbon Monoxide) from a mixture of CO, CO2 and H2, plus small amounts of CH4. The overall concept is not so different from cryogenic air separation and – it seems to me – should be easier, because of the wider spread in boiling points, between CO and H2 below and CO2/CH4 above, compared with the closeness of O2 and N2 BPs. Does anyone have experience in such a separation? Does anyone know of a contractor who would be interested in supplying such a system?
