Abstract:
Systems and methods for optimizing the recondensation of boiloff gas in liquid natural gas storage tanks are presented. In especially preferred aspects of the inventive subject matter, BOG from a storage tank is condensed using refrigeration content of a portion of LNG sendout in a direct or indirect manner, and the BOG condensate and LNG sendout portion are combined to form a subcooled stream that is then combined with the balance of the LNG sendout, to be fed to a high pressure pump. Contemplated recondensation operations advantageously occur without using otherwise needed large volume recondensers. Moreover, the condensing and subcooling operations are decoupled from the LNG sendout rate.

Claim (Index 15):
A liquid natural gas (LNG) processing plant, comprising:\n a compressor configured to compress a boiloff gas (BOG) stream of an LNG storage tank to thereby produce compressed BOG; a condensing and subcooling system configured to receive the compressed BOG and a first portion of an LNG sendout stream to thereby produce a subcooled BOG/LNG stream; a pump configured to pump the subcooled BOG/LNG stream and increase a pressure of the subcooled BOG/LNG stream; a flow control element fluidly coupled to the condensing and subcooling system and configured to receive a second portion of the LNG sendout stream and the subcooled BOG/LNG stream from the pump to thereby produce a combined subcooled sendout stream; and a high pressure pump fluidly coupled to the flow control element, the high pressure pump configured to receive the combined subcooled sendout stream from the flow control element.
