FIELD: mechanical engineering.
SUBSTANCE: invention relates to multistage cooling compression plants. Proposed plant has first compressor with first and second stages. First stage compresses first gas, and second stage compresses combined fourth gas and intermediate compressed gas from first stage of first compressor. Second compressor has first stage and second stages. First stage compresses second gas and second stage compresses combined third gas and intermediate compressed gas from first stage of second compressor. Plant has pipeline arrangement to combine discharge from second stage of first compressor and discharge from second stage second compressor to provide compressed gas. Second gas is at pressure higher than first gas, third is at pressure higher than second gas, and fourth gas is at pressure higher than third gas.
EFFECT: provision of alternative method of designing of refrigerating compressor for large capacity plants for liquefying and treatment of gas.
