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： Methods, systems, and apparatuses are provided for improving stability and efficiency of a rotation of a rotor of a compresses-gas dryer system. The compressed-gas dryer system includes a pressure vessel defining a drying zone and a regeneration zone. A compressed gas to be dried is received into the drying zone and dried compressed gas exits the drying zone. A regeneration gas is received into the regeneration zone and exits the regeneration zone. A controller receives temperature data indicative of a temperature of the compressed gas to be dried received into the drying zone, the dried compressed gas exiting the drying zone, the regeneration gas received into the regeneration zone, and/or the regeneration gas exiting the regeneration zone. And based on the temperature data, the controller is configured to control a rotational speed of a rotor provided in the pressure vessel.

摘要： Systems and methods for an atmospheric carbon dioxide removal system that includes a plurality of carbon capture containers, a plurality of fans, an air diverter, and a velocity stack. Each of the carbon capture containers has an outwardly facing side and an inwardly facing side with the inwardly facing side facing an enclosed space. The fans are disposed adjacent to the carbon capture containers. The fans are arranged to move air through the carbon capture containers in a first direction from the outwardly facing side into the enclosed space. The air diverter is disposed within the enclosed space and receives the air flowing in the first direction and redirects the air to flow in a second direction that is angled upwardly from the first direction. The velocity stack is disposed on top of the enclosed space and is configured to accelerate the flow of the air in the second direction.

摘要： Systems and methods for the efficient regeneration of sorbents, such as those used for the direct capture and separation of carbon dioxide and/or water from the atmosphere are provided. Temperature responsive bimetallic alloy strips, gores, or sheets are utilized as heat-responsive fins embedded into and extending out of the adsorbent bed to guide heated gas flows to cooler regions of the adsorbent bed undergoing regeneration. The invention allows for more rapid and more even heating of adsorbent beds to effect more efficient desorption of one or more chemical moieties adsorbed thereon. In particular, the invention is useful for the desorption of carbon dioxide from adsorption beds utilized for direct air capture (DAC) of carbon dioxide as well as the desorption of water from adsorption beds utilized for atmospheric harvesting of water.

摘要： Drying device including a drying medium with a predetermined number of drying segments which extend adjacently of each other and are associated with at least one opening at each of a first connecting end and a second connecting end, wherein the predetermined number is greater than six and wherein each connecting end includes first and second complementary concentric elements which are rotatable relative to each other round an axis. The openings are provided in the first concentric elements along a rotation ring around the axis. The second concentric elements each delimit at least two channels which open at the position of said rotation ring, so that corresponding channels of the first and second connecting end are connected to each other via the openings and the drying segments in order to allow a first airflow and a second airflow through the drying device.
