Abstract
Unreacted syngas containing CO from a Fischer-Tropsch synthesis reactor, a methanol synthesis reactor or a dual functional syngas conversion is scrubbed with an aqueous medium to adsorb at least some of the CO . At least a portion of the unreacted CO -depleted syngas is then recycled to the reactor. The aqueous medium containing absorbed CO is treated to desorb CO . A CO -enriched stream and a CO -depleted stream are recovered. A portion of the CO -enriched stream may be recycled to a syngas generator while another portion is dissolved in an aqueous phase and disposed in a marine environment and/or a terrestrial formation. The CO -depleted stream preferably is used in the scrubber to absorb CO from the unreacted syngas. The process reduces the amount of CO released into the atmosphere while improving the over-all efficiency of the syngas conversion process.
