    摘要: A method of cooling a hydrocarbon stream such as natural gas, the method at least comprising the steps of:
    (a) separating a feed stream (10) into a gaseous stream (130) and a liquid stream (70);
    (b) compressing the gaseous stream (130) to provide a compressed gaseous stream (150);
    (c) dividing the compressed gaseous stream (150) into at least a first stream (170) and a second stream (160);
    (d) cooling, preferably liquefying, the first stream (170) to provide a cooled hydrocarbon stream; and
    (e) removing the second stream (160).

    摘要: A method for recovering krypton and xenon from air comprises (a) separating an air feed stream (301) into oxygen-enriched (103) and nitrogen-enriched product streams (305); (b) reacting the oxygen-rich product stream with a hydrocarbon feed (101) in a synthesis gas generation process (105) to yield a synthesis gas stream (107) comprising hydrogen, carbon oxides, krypton, and xenon, which synthesis gas stream contains essentially no oxygen; (c) introducing the synthesis gas stream (107) into a synthesis gas conversion process (311) and converting the synthesis gas stream into a liquid synthesis product stream (321) and an unreacted synthesis gas stream (323); (d) recycling at least a portion (325) of the unreacted synthesis gas stream (323) to the synthesis gas generation process (105); (e) reducing the pressure (401) of the liquid synthesis product stream (321) to yield a two-phase reduced-pressure product stream (403), and separating (405) the two-phase reduced-pressure product stream into a final liquid synthesis product stream (409) and a gas stream enriched in krypton and xenon (407); and (f) separating the gas stream enriched in krypton and xenon into a purge gas stream (113) and a gas product stream (111) further enriched in krypton and xenon.
