FIELD: methods of liquefaction of natural gases at high content of methane and pressure exceeding 3103 kPa. SUBSTANCE: for forming gas phase and liquid product, starting gas flow is expanded to lower pressure sufficient for obtaining liquid product at point of beginning of boiling or below it. Temperature of flow exceeds minus 112 C (minus 170 F). After expansion, gas phase and liquid are separated in respective separator and liquid product is introduced in reservoir for storage at temperature exceeding minus 112 C (minus 170 F). EFFECT: reduced power requirements. 22 cl, 4 dwg, 5 tbl
