A METHOD FOR REGASIFYING LIQUEFIED NATURAL GAS AND A SYSTEM FOR REGASIFYING LUQUEFIED NATURAL GAS

摘要

A method for regasifying liquefied natural gas (LNG), comprising the steps of: inputting a batch of the liquefied natural gas to a vaporizer (102);in the vaporizer (102), converting the liquefied natural gas to a gaseous state by heating it from a first temperature (T1) to a second temperature (T2) and heating the gas from the second temperature (T2) to a third temperature (T3) higher than the critical temperature of the gas to increase the pressure of the gas to a second pressure (p2) of at least 7MPa; connecting the gas outlet of the vaporizer (102) to a storage tank (103) having a chamber with a pressure lower than the pressure of the vaporizer (102); and allowing the gas from the vaporizer (102) to flow and expand into the storage tank (103) due to the pressure difference between the vaporizer (102) and the storage tank (103).
