Abstract:
1. A closed organic Rankine cycle power and regasification system for liquefied natural gas (LNG), comprising: a) an integrated motive fluid supply of a distillation column for distilling the LNG to produce a fractionate for use in a motive fluid; b) a vaporizer in which the motive fluid in a liquid state is vaporized; c) a turbine for expanding the vaporized motive fluid; d) a condenser to which expanded motive fluid vapor is supplied, said condenser also being supplied with LNG for receiving heat from said expanded fluid vapor, wherein said LNG condenses said expanded motive fluid exiting the turbine and whereby the temperature of the LNG increases as it flows through the condenser; e) a condenser/heater for condensing vapors extracted from an intermediate stage of said turbine and heating motive fluid condensate supplied to said condenser/heater from said condenser; f) a conduit through which said motive fluid is circulated from at least the inlet of said vaporizer to the outlet of said condenser and further extends from the outlet of the condenser to the inlet of the vaporizer; and g) a line for transmitting regasified LNG.
