REFRIGERATION OR COOLING; COMBINED HEATING AND REFRIGERATION SYSTEMS; HEAT PUMP SYSTEMS; MANUFACTURE OR STORAGE OF ICE; LIQUEFACTION SOLIDIFICATION OF GASES
LIQUEFACTION, SOLIDIFICATION OR SEPARATION OF GASES OR GASEOUS; OR LIQUEFIED GASEOUS; MIXTURES BY PRESSURE AND COLD TREATMENT; OR BY BRINGING THEM INTO THE SUPERCRITICAL STATE
requiring the use of refrigeration, e.g. of helium or hydrogen; ; Details and kind of the refrigeration system used; Integration with other units or processes; Controlling aspects of the process
integrating refrigeration provided for liquefaction and purification/treatment of the gas to be liquefied, e.g. heavy hydrocarbon removal from natural gas
Purification or treatment step is integrated within one refrigeration cycle only, i.e. the same or single refrigeration cycle provides feed gas cooling (if present) and overhead gas cooling
