摘要： A method for producing a purified gas containing carbon dioxide gas, comprising: a first concentration step in which an intermediate gas having a higher concentration of carbon dioxide gas than a target gas is produced by vacuum regeneration pressure swing adsorption using a first adsorption tower that adsorbs carbon dioxide gas from the target gas containing carbon dioxide gas; and a second concentration step in which the purified gas having an even higher concentration of carbon dioxide gas than the intermediate gas is produced by vacuum regeneration pressure swing adsorption using a second adsorption tower that adsorbs carbon dioxide gas from the intermediate gas or membrane separation.

摘要： A system and method for separating and/or purification of CO2 gas from a CO2 feed stream is described. The system and method include a plurality of fixed sorbent beds, adsorption zones and desorption zones, where the sorbent beds are connected via valve and lines to create a simulated moving bed system, where the sorbent beds move from one adsorption position to another adsorption position, and then into one regeneration position to another regeneration position, and optionally back to an adsorption position. The system and method operate by concentration swing adsorption/desorption and by adsorptive/desorptive displacement.

摘要： A regenerator for regenerating a drying agent in a drying device (1) for compressed gas includes a regeneration line connected to a regeneration inlet of the drying device (1), which regenerating line (10 connects the regeneration inlet to an outlet of a blower for the supply of a regeneration gas. A heater is provided between the outlet of the blower and the regeneration inlet for heating up the regeneration gas. Between the outlet of the blower, on the one hand, and the heater, on the other hand, an additional vessel with drying agent is provided for drying the regeneration gas.

摘要： The present disclosure is directed towards sorbents, contactors, methods of using sorbents or contactors to capture CO2, and systems and devices using the sorbents or contactors to capture CO2. The methods, systems, contactors, and sorbents of the present disclosure can be advantageous over current technologies since they are relatively more robust and reduce the cost of capturing CO2, in particular from ambient air.

摘要： A method for removing a radioactive noble gas from a gas volume, includes: (a) providing the gas volume such that a dew point of the gas volume at a gas temperature of 20° C. is −20° C. or less, preferably −30° C. or less, more preferably −45° C. or less; and (b) passing the gas volume over a bed of a microporous molecular sieve including a transition metal disposed on and/or in the microporous molecular sieve, thereby adsorbing the radioactive noble gas to the bed.

摘要： Provided herein are atmospheric water harvesting systems that are tailored with an optimal adsorption threshold, based on energy cost and water availability considerations. The systems include a plurality of adsorbent modules, each containing metal organic frameworks of various adsorption thresholds. Such a design enables real time adjustment to achieve optimal harvesting conditions in changing atmospheric conditions, whether for daily or seasonal humidity variations.
