Abstract: Systems and methods are provided for regenerating a bed containing absorbed and/or adsorbed CO2 using a low value steam stream. The steam stream can have a pressure of 10 kPa-a to 50 kPa-a and a temperature of 46° C. to 81° C. The steam stream can be used to displace CO2 from the bed, resulting in formation of a low pressure stream including water vapor and CO2. The stream containing water vapor and CO2 is then passed through a liquid ring pump that includes an associated ring cooler. The ring pump provides the suction necessary to draw the low value steam stream through the bed to displace the CO2. Due to the nature of operation of the liquid ring pump, the majority of water in the steam containing H2O and CO2 can be removed within the liquid ring pump, resulting in production of a stream comprising 90 vol % or more of CO2 at a pressure of 90 kPa-a or more.

Abstract: An adsorber with minimal dead volume especially suited to reverse-flow applications comprises: a) an adsorber body; b) a first head engaged with said adsorber body; c) a first conduit extending from outside said head to at least partially through said head; and d) a first valve in flow communication with said first conduit controlling fluid flow along a flow path extending from the first valve and through the adsorber body. The adsorber is especially suited for use in a process for swing adsorption separation processes.
