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.
