Abstract: Systems and methods for heating a cryogenic fluid are provided. A cryogenic fluid can be heated to provide a partially cryogenic vaporized fluid having a first temperature. The partially vaporized cryogenic fluid can be partially vaporized to provide a second partially vaporized fluid having a second temperature. At least a portion of the second, partially vaporized, cryogenic fluid can be used to heat the cryogenic fluid to the first temperature. The second, partially vaporized, cryogenic fluid can be partially vaporized to provide a substantially vaporized cryogenic fluid having a third temperature.

Abstract: Systems and methods for adjusting the heating value of liquefied natural gas (“LNG”) are provided. LNG can be apportioned into at least two portions. A first portion can be warmed to provide a vapor-liquid mixture which can be separated in a first separator to provide a first vapor and a first liquid. The first liquid can be separated to provide ANGL and a second vapor. The first vapor can be compressed and mixed with the second vapor to provide a first effluent. At least a portion of the first effluent can be used to heat the first portion. At least a portion of the first effluent can be used as a first reflux in the first separator. At least a portion of the first effluent can be mixed with a second portion of the LNG to provide an adjusted LNG.
