Removal of water vapor from streams containing carbon dioxide and/or carbon monoxide

Methods and systems for removing water vapor from a feed gas prior to further processing the feed gas according to a downstream PSA process are described. The feed gas can include CO2 and/or CO and/or H2 and the PSA process can be used to separate components of the feed gas from one another, for ins...

Summary:Methods and systems for removing water vapor from a feed gas prior to further processing the feed gas according to a downstream PSA process are described. The feed gas can include CO2 and/or CO and/or H2 and the PSA process can be used to separate components of the feed gas from one another, for instance, for CO2 capture. Light product off of the PSA process is utilized to regenerate desiccant of a dryer used in the water vapor removal process that is carried out prior to the feed gas entering the PSA process. The water vapor removal process can be heated by providing thermal energy directly to the dryer and/or to a regenerating stream that regenerates the desiccant of the dryer. The thermal energy can be low cost energy-for instance, waste heat off of a system that provides the feed gas.
