<p>A natural gas liquefaction system according to the present invention comprises: a natural gas storage part (100) which stores the natural gas of low pressure and high temperature; a liquefied natural gas storage part (200); a main body (300) in which the liquefied natural gas of high pressure and low temperature, which is a mixed refrigerant supplied from the outside, and the natural gas of low pressure and high temperature supplied from the natural gas storage part (100) are mixed each other, exchange heat each other and are converted to the liquefied natural gas of middle pressure and middle temperature in totally; a pump part (400) which compresses and pumps the liquefied natural gas of middle pressure and middle temperature passing through the main body (300) into the liquefied natural gas of high pressure and middle temperature; a supercooling part (500) which supercools the liquefied natural gas of high pressure and middle temperature into the liquefied natural gas of high pressure and low temperature; and a first distribution transfer part (810) which distributes and transfers the liquefied natural gas of high pressure and low temperature passing through the supercooling part (500) to the liquefied natural gas storage part (200) and main body (300) so that the part of the liquefied natural gas of high pressure and low temperature passing through the supercooling part (500) is stored in the liquefied natural gas storage part (200), and the remaining part is supplied to the main body (300) as the mixed refrigerant.</p> |
