Abstract (en)
[origin: WO2020039380A1] The present invention relates to a process for the regasification of a flow of liquefied natural gas (LNG1), contained in a tank together with a quantity of Boil Off Gas (BOG), and for the production of electricity comprising: a step al) in which a flow of the LNG (LNG1) is subjected to a low-pressure pumping step, thus obtaining a flow LNG2; a step b) in which a portion of said flow (LNG1') is heated in a recondenser, thus obtaining a flow LNG1'' then combined with the flow LNG2; a step c) in which said flow LNG2 is heated in a condenser (COND); a step d) in which said flow LNG2 is subjected to a step of superheating in a superheater (SUR), thus obtaining regasified LNG; a step I) in which a flow (B0G1) of the Boil Off Gas (BOG) contained in the tank is compressed in a first step la), thus obtaining a flow of Boil Off Gas (BOGa), and in a second step lb), thus obtaining a flow of Boil Off Gas (BOGb); a step II) in which said flow of Boil Off Gas (BOGb) is cooled in a step of heat recovery in a recuperator (REG, REC1, REC2); a step III) in which said flow of Boil Off Gas (BOGb) is recondensed in the recondenser of step b); in which the step II) of heat recovery and the step c) of condensation are carried out respectively in a step 1) and 3) of a cycle which employs a flow of an organic fluid (F0A1), which, after step 1) and before step 3), is subjected to a step 2) of expansion in a turbine (TURB) for the production of electricity.
