System and Method for Liquefied Gas Regasification System with Organic Rankine Cycle

摘要

The present invention relates to a liquefied gas regasification system and method, and more specifically, to an organic Rankine cycle by supplying cooling heat obtained while vaporizing a liquefied gas to an organic Rankine cycle to produce power, and to liquefy the thermal energy obtained from the organic Rankine cycle for power production It is used to vaporize gas, and also relates to a liquefied gas regasification system and method using an organic Rankine cycle, which can improve regasification efficiency and reliquefaction efficiency by liquefying boil-off gas using the cooling heat of the liquefied gas. Liquefied gas regasification system according to the present invention, the reliquefaction unit for recovering by reliquefying the boil-off gas generated by natural vaporization of the liquefied gas; a regasification unit for vaporizing the liquefied gas and supplying the regasified gas to a consumer; and a heating medium circulation unit for supplying a heating medium to the regasification unit, and recovering the cooling medium recovered from the liquefied gas in the regasification unit to generate electricity; the re-liquefaction unit comprising: a compressor for compressing the boil-off gas; and a heat recovery device for recovering the cooling heat of the BOG before compression and cooling the compressed BOG and the heat medium recovered to the heat medium circulation unit.
