Abstract
The present disclosure provides processes and devices for adsorbing and concentrating carbon dioxide (CO2) gas directly from ambient air. The methods may comprise extracting CO2 directly from air and adding the extracted CO2 to the air circulating inside an enclosed structure. A computer system coupled to chemical sensors and a process control software program may be operatively coupled to the devices and configured to optimize and control the operating conditions of the device, via machine learning algorithms, and additionally verify carbon dioxide adsorption and enrichment for encrypted transactional carbon credits.
Claims32
A method for automatically maintaining a level of carbon dioxide (CO2) in a closed structure, comprising:
- (a) inputting air into an adsorption unit, which air comprises oxygen (O2), nitrogen (N2) and carbon dioxide (CO2);
- (b) using said adsorption unit to separate at least a portion of said CO2 from said O2 and N2 to generate an effluent stream;
- and
- (c) directing said effluent stream to said closed structure, wherein said effluent stream has a flow rate or a CO2 content that is selected to automatically maintain said level of CO2 in said closed structure.
A device for automatically maintaining a level of carbon dioxide (CO2) in a closed structure, comprising:
- an adsorption unit containing an opening for an input stream of air, which air comprises oxygen (O2), nitrogen (N2) and CO2, wherein said adsorption unit houses a sorbent cartridge that is configured to separate at least a portion of said CO2 from said O2 and N2 to generate an effluent stream containing said at least said portion of said CO2, wherein said sorbent cartridge is positioned to be exposed to the input stream of air during operation, wherein said adsorption unit contains a second opening for said effluent stream, which second opening is in fluid communication with said closed structure;
- and
- a controller operatively coupled to said adsorption unit, wherein said controller is configured to (i) control a flow rate of said input stream or said effluent stream, and (ii) automatically maintain said level of CO2 in said closed structure.
A method for enriching a content of carbon dioxide (CO2) in a closed structure, comprising:
- (a) inputting air into an adsorption unit comprising a removable sorbent cartridge, which air comprises oxygen (O2), nitrogen (N2) and carbon dioxide (CO2);
- (b) using said removable sorbent cartridge to separate at least a portion of said CO2 from said O2 and N2 to generate an effluent stream;
- and
- (c) directing said effluent stream to said closed structure.
A device for enriching a content of carbon dioxide (CO2) in a closed structure, comprising an adsorption unit comprising a removable sorbent cartridge, which reusable sorbent cartridge is configured to (i) take as input air comprising oxygen (O2), nitrogen (N2) and CO2, and (ii) separate at least a portion of said CO2 from said O2 and N2 to generate an effluent stream.
A method for generating a continuous stream of carbon dioxide (CO2) in a closed structure, comprising:
- (a) inputting air into an adsorption unit comprising a first sorbent cartridge and a second sorbent cartridge, which air comprises oxygen (O2), nitrogen (N2) and carbon dioxide (CO2);
- (b) using said first sorbent cartridge to separate at least a portion of said CO2 from said O2 and N2;
- and
- (c) unloading CO2 from said second sorbent cartridge to generate an effluent stream of CO2 from said second sorbent cartridge into said closed structure.
A device for generating a continuous stream of carbon dioxide (CO2) in a closed structure, comprising:
- an adsorption unit containing an opening for the input of atmospheric air, which comprises oxygen (O2), nitrogen (N2) and carbon dioxide (CO2), wherein said adsorption unit contains at least two sorbent cartridges;
- wherein a first sorbent cartridge is positioned to be exposed to an input stream of atmospheric air;
- and
- wherein a second sorbent cartridge positioned to be exposed to a stream of enriched air from the closed structure.
