Abstract
Methods and systems for capture of COfrom a hydrated gaseous stream are described. Systems can be utilized for direct air capture of COand incorporate a low energy temperature-vacuum swing adsorption (TVSA) process. A TVSA process can include a multi-step COcapture bed regeneration process that includes depressurization of the bed, heating of the bed, venting and purging of the bed, and cooling of the bed. Multiple beds can be cycled between COcapture and regeneration, during which captured COis recovered. Off-gas from a COcapture bed can be used in regenerating a parallel bed for increased efficiency.
