Abstract

A condensation system for a reservoir, which stores fuel cryogenically, is disclosed. A portion of the fuel exists as a boil-off gas with a first vapor quality. The condensation system includes an absorption unit coupled to the reservoir and is configured to receive and mix the boil-off gas with a refrigerant, forming a liquid solution. A distillation unit is coupled to the absorption unit to receive the liquid solution at a supplemented pressure, and is configured to separate the fuel to a gaseous state from the liquid solution. Further, a cooling circuit is configured to receive the fuel in the gaseous state from the distillation unit at the supplemented pressure and a supplemented temperature, and deliver the fuel to the reservoir at a lower pressure and a temperature, with a vapor quality lower than the first vapor quality.
