Abstract: A system in one embodiment includes a heat exchanger, a detection unit, and a controller. The heat exchanger includes a first passage and a second passage configured for exchange of heat therebetween. The first passage is configured to receive a boil-off gas stream of a first cryogenic fluid. The second passage is configured to receive a liquid stream of a second cryogenic fluid. The detection unit is configured to detect a characteristic of the boil-off gas stream. The controller is configured to, responsive to information acquired from the detection unit corresponding to the characteristic, control the flow of the second cryogenic fluid to provide sufficient exchange of heat from the boil-off gas stream via the heat exchanger to condense at least a portion of the boil-off gas stream. A liquid stream of the first cryogenic fluid is output from the first passage and returned to a first tank.

Abstract: A system in one embodiment includes a mixing module (330), an oxidation module (360), and a heat exchanger (320, 350). The mixing module (330) is configured to receive and mix a boil-off gas stream from a cryotank (310). The oxidation module (360) is configured to receive the mixed stream, and to oxidize the boil-off gas in the mixed stream to produce an exhaust stream. The heat exchanger (320, 350) is configured to exchange heat between streams passing through a first passage configured to receive at least a portion of the exhaust stream, and a second passage configured to receive a fluid including the boil-off gas. The heat exchanger (320, 350) is configured to heat the fluid including the boil-off gas and cool the at least a portion of the exhaust stream. The fluid including the boil-off gas is heated by the heat exchanger (320, 350) upstream of the oxidation module (360).

Abstract: A counter-flow heat exchanger including a core region and a plenum region. The core region including a first set of heat exchanging passageways and a second set of heat exchanging passageways disposed at least partially therein. A plenum region is disposed adjacent opposed distal ends of the core region. Each of the plenum regions including a fluid inlet plenum, a fluid outlet plenum and a tube plate disposed therebetween. The first set of heat exchanging passageways is truncated and defines a first tube-side fluid flow path in a first direction. The second set of heat exchanging passageways defines a second tube-side fluid flow path in a second opposing direction. Each of the heat exchanging passageways extending from a fluid inlet plenum to a fluid outlet plenum. The tube plates and the core region include one of a cast metal formed thereabout each of the heat exchanging passageways or a braze bond formed between each of the heat exchanging passageways.

Abstract: A system in one embodiment includes a detection unit, a boil-off auxiliary power unit, and a controller. The detection unit is configured to detect a characteristic of a boil-off gas stream from a cryotank configured to hold a cryogenic fluid. The boil-off auxiliary power unit is configured to receive the boil-off gas stream and use the boil-off gas stream to provide auxiliary power to a vehicle system. The controller is configured to acquire information from the detection unit corresponding to the characteristic; determine, using the information acquired from the detection unit, an available boil-off auxiliary energy that is available from the boil-off auxiliary power unit; determine a mode of operation of the vehicle system; determine a required auxiliary energy for the vehicle system; and to operate the auxiliary power unit based on the available boil-off auxiliary energy, the mode of operation, and the required auxiliary energy.
