Embodiment Construction
[0049] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0050] Examples such as figure 1 , 2 , 3, 4, 5, 6, and 7:
[0051] 1. A natural gas liquefaction process, the liquefaction process comprises a pretreatment unit 10, a compression unit 11, a liquefaction unit 12, a storage unit 13 and a loading unit 14, and its main steps are:
[0052] 1), the raw natural gas first passes through the pretreatment unit 10 to separate the large particles of impurities contained in it and remove the moisture;
[0053] 2), the natural gas processed by the pretreatment unit 10 enters the compression unit 11 to be compressed to 10-25MPa;
[0054] 3), the pressurized natural gas enters the liquefaction unit 12 to be converted into liquid natural gas LNG;
[0055] 4), liquefied natural gas LNG input storage unit 13 preserves;
[0056]5), the liquefied natural gas LNG in the storage unit 13 is loaded through the ...
