Abstract: Systems and methods for capturing gases are disclosed. The system may include a casing including at least one inlet, a disc turbine and a rotating plate arrangement. The disc turbine is housed inside the casing and comprises a plurality of discs mounted on shaft. The discs of the plurality of discs are spaced apart in axial direction defined by a central axis of the shaft and each of the discs includes at least one disc opening. The discs of the plurality of discs and the shaft are driven rotationally by admitting a solvent through the at least one inlet and into an interior of the casing. The at least one disc opening of each of the plurality of discs guides a flow of introduced gas and the solvent along the axial direction. The rotating plate arrangement is housed in the casing.

Abstract: A method to reduce carbon dioxide emissions from an engine including combusting fuel in the engine to yield exhaust gas, feeding a coolant to the engine head at a first temperature, and recovering an engine coolant at a second temperature. The method further includes flowing a first portion of the engine head coolant through a restricting valve to increase a temperature of the first portion of the engine head coolant to a third temperature, feeding the first portion of the engine head coolant from the restricting valve to the engine block, and recovering an engine block coolant at a fourth temperature. A second portion of the engine head coolant is recirculated back to the engine head. A system including an engine head, an engine block, a restricting valve in a first flow line, and a second flow line exiting the engine head to recirculate coolant back towards the engine head.

Abstract: A hydrogen generation and carbon capture system includes a fuel reformer, hydrogen purifier, fuel cell, three heat exchangers, two knockout drums, absorber, burner feed pressure regulator, burner, flash tank, solvent trim cooler, and condenser. A process for hydrogen generation and carbon capture includes pumping, heating, and reforming a fuel and water feed. The process includes extracting hydrogen from a raw syngas, directing hydrogen to a fuel cell, separating liquid from a cooled carbon monoxide and carbon dioxide rich syngas mixture and feeding this stream to an absorber. The process includes reducing pressure and burning the syngas mixture, heating the carbon dioxide rich solvent stream, and cooling the cooled regenerated solvent. The process includes heating the heated carbon dioxide rich solvent stream, separating carbon dioxide from the stream, condensing the carbon dioxide stream, and separating liquid from the gas/liquid mixture.
