FIELD: process engineering.
SUBSTANCE: invention relates to liquefaction of fraction enriched with hydrocarbons. Proposed process comprises the steps that follow. This fraction is cooled and liquefied by indirect heat exchange with refrigeration mix of flow circuit. This fraction is cooled and liquefied by indirect heat exchange with completely evaporated refrigeration mix of flow circuit. Compressed refrigeration mix of flow circuit is pre-cooled by flow circuit pure substance. Refrigeration mix composition and/or refrigeration mix flow circuit compressor final pressure is selected to make refrigeration mix completely liquefied with the help of pure substance flow circuit.
EFFECT: higher efficiency at electric power saving.
