SYSTEM FOR VAPORIZING LIQUEFIED NATURAL GAS

摘要

PURPOSE: An LNG vaporization system is provided to offer the heat for vaporizing the LNG and collect the energy. CONSTITUTION: An LNG vaporization system comprises a compressor(110), an expander(120), an evaporation portion(130), a refrigerator(140) and a heat exchanger(150). The compressor compresses the working fluid. The expander expands the working fluid, produces the energy and drives the compressor. The evaporation portion vaporizes the LNG by heat-exchanging the working fluid which is expanded and exhausted from the expander. The refrigerator cools the compressed working fluid to a predetermined temperature. The heat exchanger comprises a first line and a second line. The heat-exchanged working is offered through the first line to the compressor. The working fluid offered from the refrigerator is provided through the second line to the expander.
