摘要： A process of treating a feed in an adsorption separation zone comprising at least two adsorbent beds and a trim bed is disclosed. The process comprises displacing feed from a first adsorbent bed to a trim bed by feeding a desorbent from a second adsorbent bed to the first adsorbent bed while displacing spent desorbent from the trim bed. After discontinuing the first adsorbent bed displacement, an adsorber trim fluid to the first adsorbent bed to recover the remaining treated feed in the head. After discontinuing adsorber trim fluid to the first adsorbent bed; a trim displacement fluid is passed to the trim bed to displace feed from the trim bed.

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 combined atmospheric water extraction and atmospheric carbon capture are provided. Fan(s) are adapted circulate ambient air to one or more atmospheric water extraction devices and atmospheric carbon capture devices. Water extracted from the atmosphere is heated to produce steam, which is used to release carbon absorbed by the atmospheric carbon capture devices for use in carbon storage and/or fuel production. The system may be powered by renewable energy sources. Water extracted from the atmosphere also undergoes electrolysis to isolate hydrogen, such as for use in fuel production.

摘要： Disclosed is a flue gas low-temperature adsorption denitration system and process. The system includes a booster fan, a cold energy recoverer, a flue gas cooling system, a flue gas switching valve, and two denitration adsorption towers. An inlet of the booster fan is in communication with an inlet flue gas pipeline. The booster fan, the cold energy recoverer, the flue gas cooling system, the flue gas switching valve, and the denitration adsorption towers are sequentially communicated. An outlet of the flue gas switching valve is in communication with each of the two second denitration adsorption towers. Flue gas outlets of the two denitration adsorption towers are in communication with a flue gas manifold. The flue gas manifold is communicated with the cold quantity recoverer. Two denitration adsorption towers take turns to carry out denitration and regeneration processes, so that continuous denitration operations of the system can be achieved.
