  • Method of operating a syngas plant for a wide range of hydrogen and co co-production
    Patent number: 11066300
    Abstract: A method for achieving a gas with a variable hydrogen to carbon monoxide ratio in a system including splitting a warm raw syngas stream into a first portion and a second portion, the second portioning having a portion flowrate. Sending the first portion of the warm raw syngas stream a carbon monoxide separator, thereby producing a first hydrogen enriched stream and a carbon monoxide rich stream. Sending the second portion of the warm raw syngas stream to a water/gas shift reactor, thereby producing a shifted syngas stream. Combining the first hydrogen enriched stream and the second hydrogen enriched stream and sending the combined stream to a hydrogen separator, thereby producing a product hydrogen stream having a hydrogen flowrate, and varying the hydrogen flowrate by increasing the portion flowrate.
