Abstract
An apparatus for removing an acid gas from a feed gas stream includes an absorber and an electrochemical regenerator. The absorber is adapted for separating the acid gas from the feed gas feed stream using a lean carbon capture solvent. The electrochemical regenerator is connected to the absorber and adapted for (a) regenerating the carbon capture solvent and (b) generating hydrogen gas. A method for removing acid gas from a feed gas stream includes steps of separating, delivering, releasing, generating and returning.

An apparatus for removing an acid gas from a feed gas stream, comprising:
- an absorber adapted for separating the acid gas from the feed gas feed stream using a lean carbon capture solvent;
- and
- an electrochemical regenerator connected to the absorber and adapted for (a) regenerating the carbon capture solvent and (b) generating hydrogen gas.
A method of removing an acid gas from a feed gas stream, comprising:
- separating the acid gas from the feed gas stream in an absorber by contacting the feed gas stream with a lean carbon capture solvent thereby generating a rich carbon capture solvent;
- delivering the rich carbon capture solvent from the absorber to an electrochemical regenerator;
- releasing the acid gas from the rich carbon capture solvent in the electrochemical regenerator to regenerate the lean carbon capture solvent;
- generating hydrogen gas in the electrochemical regenerator;
- and
- returning the lean carbon capture solvent to the absorber.
