Abstract: Aspects disclosed herein provide systems and methods for mixing and dispensing fuel. The method includes flowing cryogenic fuel from a storage tank through a cold portion of a process heat exchanger to a first vaporizer, flowing the cryogenic fuel from the first vaporizer through a warm portion of the process heat exchanger to obtain an intermediate temperature fuel exiting the process heat exchanger, and separating the intermediate temperature fuel into a first stream and a second stream. The method further includes directing the first stream through a second vaporizer to obtain a warm stream, combining the warm stream and the second stream to obtain a target fuel temperature stream, and dispensing the target fuel temperature stream through at least one dispenser.

Abstract: A method for mixing and dispensing fuel includes flowing fuel from a tank toward a first flow path and a second flow path and separating the fuel into a first stream and a second stream. The method includes flowing the first stream in the first flow path through a vaporizer to a heat exchanger, flowing the second stream in the second flow path to the heat exchanger, flowing the first stream through a warm portion of the heat exchanger to exchange heat with the second stream, and flowing the second stream through a cold portion of the heat exchanger to exchange heat with the first stream. The method further includes flowing the first stream and the second stream from the heat exchanger to a mixing point, combining the first stream and the second stream to obtain a target stream, and dispensing the target stream through a dispenser.

Abstract: A method for manufacturing a heat exchanger includes: providing a porous material that has a porosity of about 30% to about 80%; forming an oxide layer on a surface of the porous material by heat treating the porous material at a temperature in a range of 600° C. to 900° C. for a time period in a range of 8 hours to 12 hours in air; and integrating the porous material into a cold side flow passage of the heat exchanger.

Abstract: A heat exchanger includes a porous material in a cold side flow passage. The porous material is configured to distribute a liquid phase throughout the cold side flow passage through capillary action.
