METHOD FOR ETHANE RECOVERY, USING A REFRIGERATION CYCLE WITH A MIXTURE OF AT LEAST TWO COOLANTS, GASES OBTAINED BY SAID METHOD, AND INSTALLATION THEREFOR |
摘要 |
The invention concerns a method and an installation for refrigerating gas mixtures, for cryogenic separation of a pressurised gas (1) constituents. The method comprises a refrigerating cycle wherein a fluid (13) is separated in a separator tank (B2) into a less volatile fraction (4), for producing refrigeration at a relatively high first temperature in an exchanger (E1), and into a more volatile second fraction (5) for producing refrigeration at a relatively low temperature in an exchanger (E2). The heated and expanded fractions (4, 5) are brought together then compressed in a compressor (K1). A fraction (26) derived from said compressor (K1) is cooled to supply the fraction (13).
