1. A regasification plant for liquefied natural gas comprising:
a liquefied natural gas fractionation unit that forms a process product from the liquefied natural gas;
a cooler and a pump fluidly coupled to the fractionation unit and configured to allow liquefaction and pressurization of the process product to so form a liquefied and pressurized process product;
a heat source fluidly coupled to the pump and configured to heat the liquefied and pressurized process product to thereby produce a heated process product; and
wherein at least one component of the fractionation unit uses refrigeration content of the liquefied natural gas, and wherein an expander expands the heated process product to produce work.
