    摘要： The invention relates to a method for the cryogenic separation, the cooling or the liquefaction of a fluid using an exchange line, that comprises extracting from said exchange line at least one dual phase fluid (11), separating said dual phase fluid into at least one vapour fraction (4) and one liquid fraction (5) in a phase separator (40), expanding at least one portion of the liquid fraction (5) using a first expansion means (60, 90), reinjecting, reheating and at least partially vaporising said expanded liquid fraction in the exchange line, the first expansion means being a valve, wherein during the cooling of said exchange line, at least a fraction of the fluid extracted from the exchange line (2, 4 or 5) and/or from the phase separator (40) is expanded in second expansion means (61, 71, 81, 91) parallel to the first expansion means (6), while during a normal operation, the second expansion means is essentially closed.

    摘要： In a process for the separation of a gas mixture at superatmospheric pressure by partial condensation at cryogenic temperatures and wherein the separated condensate and uncondensed vapor are passed back as returning streams in indirect countercurrent heat exchange relationship with the incoming feed mixture, the power required for providing the refrigeration and energy requirements for the separation are reduced by supplying said requirements by means of a heat pump alone or together with at least one separate refrigeration cycle and/or some Joule-Thomson expansion of the condensate, and in the heat pump a compressed multi-component gaseous medium is condensed by heat exchange with said returning streams over a first temperature range and then expanded by Joule-Thomson expansion, and the expanded condensate is evaporated by heat exchange with the feed gas mixture over a lower temperature range than said first temperature range, and recycled for recompression.
