ABSTRACT:
This invention relates to a gas liquefying method in which a power saving of a compressor for refrigerant can be attained. The pre-cooled gas flow, the high pressure vapor flow and the high pressure condenced liquid flow obtained by gas-liquid separation of partial condensed high pressure multi-component refrigerant are fed from the upper part of the high temperature region of the upright plate-fin type heat exchanger having its upper side applied as the high temperature region and its lower side applied as the low temperature region so as to be cooled, the cooled gas flow and the high pressure vapor flow are fed from the upper part of the low temperature region into the different flow passages so as to be cooled there, the liquefied gas is recovered from the lower part of the low temperature region, the vapor part and the liquid part obtained by expanding the liquefied high pressure vapor flow extracted from the lower part of the low temperature region are separated into gas and liquid, thereafter they are mixed to each other, fed from the lower part of the different flow passage in the low temperature region, used as the source of cold heat, then the mixture is extracted from the upper part of the low temperature region, mixed with a flow obtained by expanding the high pressure condensed liquid flow of the multi-component refrigerant passed through the high temperature region and further the mixture is divided into gas and liquid, the vapor part and the liquid part are mixed to each other, fed from the lower part of the different flow passage in the high temperature region and used as a source of cold heat, and extracted from the upper part of the high temperature region, compressed and cooled and further it is circulated as the partial condensed high pressure multi-component refrigerant.
