摘要

FIELD: liquefaction of gases or gaseous mixtures. SUBSTANCE: method involves cooling of natural gas by expansion thereof; mixing of natural gas before cooling with liquid vapor or gas having molar mass M>=40 kg/mol with liquid vapor or gas amounting to 10-50 % by total weight of mixture; accelerating of mixture to speed exceeding sound speed into mixture. EFFECT: reduced cost, simplified technology and increased efficiency.
