    摘要: A system for maintaining a substantially constant pressure within an ullage space of a cryogenic storage tank is provided. The system includes a compressor configured to receive fuel gas from the cryogenic storage tank, and compress the fuel gas to produce heated fuel gas. The system further includes a heat exchanger in flow communication with the compressor and configured to cool the heated fuel gas to produce cooled fuel gas, and a turbine in flow communication with the heat exchanger and configured to expand the cooled fuel gas to produce a gas and liquid mixture having a predetermined liquid to gas ratio, and discharge the gas and liquid mixture into the cryogenic storage tank.
