After desulfurization and decarburization through low-temperature washing, how can hydrogen be removed from the purified gas to obtain high-purity carbon monoxide? (What process is better to use?) ）
Since the original poster is using low-temperature washing, why not cool further by employing cryogenic methods to separate and purify CO, given that at the same pressure, the condensation temperature of hydrogen is much lower than that of CO?
