Abstract

1373385 Liquefying gases L'AIR LIQUIDE SOC ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE 20 Dec 1971 [21 Dee 1970] 59188/71 Heading F4P In a refrigeration cycle in which an expanded coolant mixture is used in three heat exchangers 10, 20, 30 to effect liquefaction of a stream 1, e.g. of natural gas, the coolant mixture is compressed by a two stage compressor 2 from a low to a high pressure, partially fractionated in a separator 3, the liquid fraction is expanded through a valve 104 to an intermediate pressure, further fractionated in a separator 103, the liquid fraction being fed through exchanger 10 to a second expansion valve 4' before being fed, as the coolant, to the exchanger 10, and returning at low pressure, to the compressor 2. The gas fraction from separator 103 is returned to the input of the second stage 2" of the compressor via line 105, and the gas fraction from separator 3 is fed through exchanger 10 to a further separator 13 from which the liquid fraction is cooled and expanded through valve 14' to provide the coolant for exchanger 20. The gas fraction from separator 13 after passing through exchangers 20, 30 is expanded at valve 15' to form the coolant for exchange 30. The coolant in exchangers 20, 30 is returned via lines 26, 16 and 6 to the compressor 2. In a modification, Fig. 3 (not shown), the liquid fraction from separator 3 passes through a further heat exchanger (200) before expanding through valve 104, the expanded liquid fraction forming the coolant for this exchanger (200) before being fed to separator 103, the liquid fraction from separator 103 being cooled in this exchanger (200) before being fed through exchanger 10. The gas stream 1 being liquefied may be passed through this further exchanger (200) before entering the exchanger 10. The coolant mixture may comprise a saturated hydrocarbon mixture of relatively low methane content together with a small percentage of nitrogen.
