FIELD: gas industry.
SUBSTANCE: method for liquefying natural gas flow is proposed. The gas is cooled in several asymmetric pre-cooling contours arranged in parallel. A mixed refrigerant is used in cooling contours.
EFFECT: use of the invention allows for more control of each refrigerant flows during the cooling process and simplifies process management by allocating heat exchangers to perform similar functions.
