Abstract:
A system for production of CO-rich product gas, the system including a steam shift reactor for production of shifted synthesis gas from high pressure raw synthesis gas; a hydrogen separation unit to separate the shifted synthesis gas into a hydrogen-rich product comprising a greater volume percentage of hydrogen than the shifted synthesis gas and a hydrogen-lean tailgas comprising a reduced volume percentage of hydrogen than the shifted synthesis gas; an oxidizing unit adapted to oxidize the hydrogen-lean tailgas with purified oxygen comprising primarily oxygen, to produce an oxidized product gas comprising water vapor and carbon dioxide; and dehydration apparatus adapted for removal of water vapor from the oxidized product gas to provide CO-rich product gas comprising at least 95% COby volume; wherein the proportional critical temperature of the CO-rich product gas is near or greater than the critical temperature of pure CO.
