An absorption chiller system includes a generator section, a condenser section, an evaporator section and an absorber section all in fluid communication with each other and which operate to circulate a refrigerant therethrough. The evaporator section includes a transport membrane heat exchanger. The transport membrane heat exchanger includes a first and a second flow path. The first flow path is operable to flow the refrigerant therethrough under a vacuum pressure that is low enough to vaporize the refrigerant within the first flow path. The second flow path is operable to pass a fluid having water therethrough. Both water and heat are transferred from the fluid in the second flow path to the refrigerant in the first flow path through a membrane-based material of the transport membrane heat exchanger, such that the fluid passing through the second flow path has at least a portion of its water removed and is cooled.

A carbon dioxide capture system includes a first capture tank containing carbon dioxide absorbent material which operates to absorb carbon dioxide from a flow of exhaust gas from an internal combustion engine. A heat exchange loop is in heat exchange communication with the first capture tank and further in heat exchange communication with one of the flow of exhaust gas or a flow of engine coolant from the internal combustion engine. A heat exchange fluid is operable to flow through the heat exchange loop. The heat exchange fluid operates to transfer heat from the exhaust gas or the engine coolant to the first capture tank. The heat from the exhaust gas or the engine coolant operates to release a portion of the carbon dioxide absorbed by the carbon dioxide absorbent material in the first capture tank.

A method of generating electrical power includes expanding a flow of exhaust gas from a combustion process as the exhaust gas passes through a turbo-expander disposed on a turbo-crankshaft. The flow of exhaust gas from the turbo-expander is routed through a first flow path of an exhaust gas heat exchanger.

The flow of exhaust gas from the turbo-compressor is routed through a second flow path of the exhaust gas heat exchanger. Heat from the first flow path is transferred to the second flow path to cool the exhaust gas in the first flow path and heat the exhaust gas in the second flow path. Electrical power is generated from a generator disposed on the turbo-crankshaft.

Engine waste heat is communicated to the heat exchange unit and energy from the waste heat is used to drive the air compressor device, causing the air compressor device to draw in ambient air through the ambient air intake, compress the ambient air, and deliver compressed air to the engine through the compressed air outlet.
