1. A LNG regasification plant comprising:

  • a liquefied natural gas storage vessel having a receiving port that is configured to receive liquefied natural gas and further having separate liquid withdrawal and vapor withdrawal ports that are configured to allow separate withdrawal of a liquefied natural gas liquid and a liquefied natural gas vapor from the storage vessel;

    a fractionator that is fluidly coupled to the storage vessel and configured to receive a fractionator feed, wherein the fractionator is configured to allow production of (a) an overhead product comprising C2 and lighter components and (b) a bottom product comprising C3 and heavier components;

    a first conduit configured to combine the bottom product comprising C3 and heavier components with the liquefied natural gas vapor from the storage vessel to thereby form a two-phase mixture;

    a heat exchanger configured to condense the two-phase mixture using refrigeration content of the natural gas liquid to thereby form the fractionator feed; and

    an overhead condenser coupled to the fractionator and configured to allow refrigeration content of the liquefied natural gas liquid to condense the overhead product comprising C2 and lighter components; and

    a second conduit configured to combine the condensed overhead product comprising C2 and lighter components with the liquefied natural gas liquid to so produce a sendout stream.
