Abstract
The present disclosure is directed to a high temperature method to adsorb carbon dioxide onto an ion-exchange resin and/or regenerate the carbon dioxide-loaded ion-exchange resins.
Claims25
A method, comprising:
- contacting an ion-exchange resin with the a target component-containing gas stream;
- absorbing at least a portion of the target component from the target component-containing gas stream onto the ion-exchange resin at an absorption temperature of at least 20° C. to form a target component-loaded resin;
- regenerating the target component-containing resin by removing, from the target component-containing resin, the target component at a sorbent regeneration temperature of more than 100° C. to form a regenerated ion-exchange resin;
- and
- recycling the regenerated ion-exchange resin to the contacting step.
In a system to remove a target gas component from a gas stream, the gas stream comprising the target gas component, by contacting the gas stream with an ion-exchange resin to remove at least a portion of the target gas component to form a purified gas stream and a target gas component loaded ion-exchange resin, a tangible and non-transient computer readable medium comprising microprocessor readable and executable instructions that, when executed, perform operations comprising:
- determine a concentration of a target gas component in at least one of the gas stream and the purified gas stream and, when a determined relationship involving the determined concentration of the target gas component in the at least one of the gas stream and the purified gas stream is deemed to exist, cause the operation to be performed;
- regenerating the target component-containing ion-exchange resin by removing, from the target component-containing resin, the target component at a sorbent regeneration temperature of more than 100° C. to form a regenerated ion-exchange resin.
