Described is a system for capturing and recovering carbon dioxide (CO) from multiple distinct waste heat sources. The system includes an absorber for extracting COfrom exhaust gas into a solvent stream selective for absorbing COand creating a rich solvent stream. A solvent regenerator converts a first fraction of the rich solvent stream into a lean solvent stream and a crude COvapor. A cross exchanger exchanges heat between lean and rich solvent streams. Several heat exchangers are associated with the solvent regenerator to transfer heat from multiple distinct waste heat sources into a second fraction of the rich solvent stream as well as recover waste heat from the multiple distinct waste heat sources. A compressor converts the crude COvapor into a concentrated pressurized COproduct, and a COstorage tank receives and stores the COproduct.

A device for reducing emissions from an internal combustion engine having a close-coupled catalyst including an underbody catalyst and a hydrocarbon trap disposed downstream of the close-coupled catalyst. The device includes a heat exchanger and a liquid water knockout disposed downstream of the close-coupled catalyst. The device includes a four-valve system configured to dynamically adjust a flow path of exhaust from the internal combustion engine through the underbody catalyst, hydrocarbon trap, or both, to reduce emissions. A method for reducing emissions including feeding an exhaust gas from the internal combustion engine to the close-coupled catalyst, producing a catalyzed exhaust gas. The method includes flowing the catalyzed exhaust gas from the close-coupled catalyst to the four-valve system.

A method for the subterranean regeneration of CO-philic solvents and the sequestration of carbon dioxide may include exposing the CO-philic solvent to a carbon dioxide-containing gas in an absorber to allow the CO-philic solvent to absorb at least a portion of the carbon dioxide in the carbon dioxide-containing gas, thereby producing a CO-containing solution. The CO-containing solution may be supplied to one or more porous rock fractures via one or more injection conduits in fluid communication with the one or more porous rock fractures. The CO-containing solution may be heated via heat provided by one or more rock fractures in order to release at least a portion of the absorbed carbon dioxide into the one or more rock fractures and thereby regenerate the CO-philic solvent. At least a portion of the released carbon dioxide may be sequestered by adsorbing the carbon dioxide within the porous rock fractures or by reacting the released carbon dioxide with the porous rock fractures to form stable carbonates. The regenerated CO-philic solvent may be transported from the one or more porous rock fractures via one or more production conduits.
