Abstract
Systems and methods for transporting and managing LNG are contemplated. A source of LNG is pumped to a pressure higher than a consumer pressure, and is vaporized to provide vaporized LNG. The vaporized LNG is transported from a first location to a second location without the need for cryogenic equipment. At the second location, the vaporized LNG is expanded to the consumer pressure or a second pressure below the consumer pressure to generate refrigeration content suitable to reliquefy at least a portion of the vaporized LNG. A reliquefied natural gas is generated at the second location while providing a natural gas product to a downstream consumer at the consumer pressure.
Claims17
A method of providing a reliquefied natural gas product at a second location, comprising:
- providing liquefied natural gas (“LNG”) from an LNG source;
- pumping the LNG to a pressure above a consumer pressure to thereby form pressurized LNG;
- vaporizing the pressurized LNG at a first location to thereby form a pressurized natural gas;
- transporting the pressurized natural gas from the first location to the second location;
- splitting, at the second location, the pressurized natural gas into a first stream and a second stream;
- expanding, at the second location, the second stream of the pressurized natural gas to a second pressure to generate a mixed product stream;
- separating the mixed product stream into;
- an overhead product stream having a refrigeration content, and a reliquefied natural gas product;
- before the step of expanding cooling the second stream of the pressurized natural gas product using the refrigeration content of the overhead product stream;
- and
- combining the first stream and the overhead product stream to generate a natural gas product.
