Abstract

An integrated refueling system comprises a fluid circuit including multiple flow paths for directing natural gas to a natural gas liquefier. A portion of the resulting liquefied natural gas is provided to a liquefied natural gas delivery location. Another portion of the liquefied natural gas may be provided to a compressor and subsequently a heat exchanger/vaporizer to produce compressed natural gas. The heat exchanger/vaporizer may utilize the lower temperature of liquefied natural gas to precool incoming gaseous natural gas while simultaneously vaporizing the pressurized, liquefied natural gas to form the compressed natural gas. Compressed natural gas may be provided at a compressed natural gas delivery location.
