Abstract: A capture vessel is provided that is configured to capture carbon dioxide (CO2) according to a thermal swing adsorption (TSA) process. The capture vessel includes capture media that are configured to adsorb CO2 from an exhaust gas during a CO2 capture stage to produce a first N2 gas that exits the capture vessel, receive a mixed stream of CO2 and water vapor during a wet regeneration stage, adsorb water from the mixed stream of CO2 and water vapor and release adsorbed CO2 during the wet regeneration stage to produce a CO2 stream, receive a first heated N2 gas and release adsorbed water due to evaporation caused by the first heated N2 gas during a drying stage, and receive a cooled gas during a cooling stage such that an absorption capacity of the capture media for CO2 capture is increased for a next CO2 capture stage.

Abstract: A method and system for purifying a carbon dioxide feed stream in which the carbon dioxide feed stream is cooled and partially condensed to remove water upstream of an adsorber to produce a dry carbon dioxide stream. The dry carbon dioxide stream is further cooled and partially condensed in a carbon dioxide purification unit to form a carbon dioxide product stream. Excess refrigeration duty from the carbon dioxide purification unit is used to cool the carbon dioxide feed stream.

Abstract: There is provided a liquid water harvester based on a valve-controlled active air supply and belongs to the field of liquid water harvesters. The present disclosure aims to address the problem of low airflow speed, high environmental humidity requirements, and auxiliary heating of an adsorption stage in the current atmospheric water harvesting technologies. In the present disclosure, the active air supply device is used to speed up the air circulation in the harvester so as to greatly shorten the adsorption time of the moisture absorbing material for the water vapor in the air and improve the heat dissipation of the micro-nano structure condensation surface. The electric valve controls the air circulation circuit and cooperates with the active air supply device. In this case, only one active air supply device can be used to complete the air supply and the condensation heat dissipation at the same time.
