Abstract

1,149,560. Refrigerating; gas liquefaction process. AIR PRODUCTS & CHEMICALS Inc. 22 Dec., 1966 [28 Dec., 1965], No. 57403/66. Heading F4H and F4P. In a refrigeration process, compressed helium is cooled by heat exchange, expanded in an expansion engine without liquefaction and further expanded by Joule- Thomson expansion so as at least partially to liquefy. As illustrated, helium is compressed in stages 12, 15 and 17 and passed through heat exchanger 21, liquid nitrogen bath 78, and heat exchangers 28 and 31 to a reciprocating or turbine type expansion engine 33. The discharge pressure of the engine is above the critical pressure of helium. Gas from the engine passes directly to a Joule- Thomson valve 35 and partially liquefied gas is passed into a phase separator 37. Liquid helium may be withdrawn from the system through a line controlled by a valve 38. Vapour from the separator 37 may, by closing a valve 39 and opening valve 40 and 41, be passed through a coil 44 to cool a chamber 45 and then be passed through the shell spaces of heat exchangers 31, 28 and 22 to the input of compressor stage 12. By closing the valves 40 and 41, and opening the valve 39, the vapour may be passed direct to the shell spaces. If product liquid helium is not required, the valve 38 may be closed and a mixture of vapour and liquid passed to the chamber 45. The heat exchanger 28 is cooled by a compression circuit including a compressor 55 drawing helium from the compressor stage 17 and passing it through a heat exchanger 58, the nitrogen bath 78 and a heat exchanger 69 to an expansion turbine 65. Helium from the turbine is passed through heat exchangers 28, 69 and 58 to be returned to a point between the compressor stages 12 and 15. The illustrated compression circuit may be replaced by an independent circuit. The colder components of the system are contained within a chamber 73 and liquid nitrogen from a source is passed through the walls of the chamber to the bath 78. Vapourized nitrogen from the bath 78 passes through heat exchangers 22 and 58 to an exhaust 86. Valves 90 and 91 are controlled in accordance with the amount of liquid helium withdrawn from the process so that the cooling power of the compression circuit increases with the amount of liquid helium required. Preferred operating conditions are disclosed.
