Abstract

1435773 Liquefaction processes H KRIEGER 31 Aug 1973 [1 Sept 1972] 41169/73 Heading F4P In a process for liquefying a stream 30 of natural gas, the apparatus for producing cold comprises a cascade circuit b and a precooling circuit a, coolant in the precooling circuit a being compressed by compressor 50 and cooled by water cooler 51 and being passed on to path 11 of a heat exchanger 1 where it is in heat exchange with path 12 of the exchanger, path 12 being fed with completely evaporated and expanded coolant produced by fractional condensations at 34, 36 and subsequent expansion and heating, superheated vapour being supplied from compressor 32 and water cooler 33 of the cascade circuit a to path 15 of a heat exchanger 2 prior to the fractional condensation, path 15 being in heat exchange with coolant in the precooling circuit a which, after passing through path 11 of exchanger 1, is expanded by throttle 56 and then fed to path 13 of exchanger 2. In precooling circuit a, compression and cooling of the coolant at 50, 51 is followed by feeding of the coolant to a phase separator 52, the liquid being pumped by pump P and then cooled by cooler 54, whilst the vapour is again compressed at 55 before passing to water cooler 54. From cooler 54 the coolant is drawn off substantially as liquid and after passing through path 11 is supercooled. It is then drawn off from throttle 56 as saturated vapour and is totally evaporated in path 13 of exchanger 2. In cascade circuit b, superheated vapour, produced by compression and cooling at 32, 33, is partly condensed in path 15 of exchanger 2 and passed to phase separator 34, liquid being drawn off through channel 19 of exchanger 3 whereby it is supercooled, the coolant being then expanded in throttle 35, partly evaporated in path 18 and totally evaporated and superheated in path 14. Vapour from 34 is partly condensed in path 20, fed to separator 36, and the vapour and liquid drawn off recombined, after the liquid is cooled in path 23 and expanded at throttle 37 and the vapour condensed in paths 24, 27 and expanded at throttle 38, so that the combined flow passes through paths 22, 17 to be completely evaporated before entering exchanger 1.
