Abstract

Fremgangsmåte for å skille en C2-, C2/CO2-, C2+ eller C3+-rik fraksjon fra en hydrokarbonrik fraksjon, hvor den hydrokarbonrike fraksjon trykkavlastes i ett eller flere trinn og underkastes rektifikasjon for å skille fra metan. Den metanfattige fraksjon oppnådd ved å skille fra metan underkastes fraskillelse av C2, C2/C02, C2+ eller C3+ ved rektifikasjon. Ifølge oppfinnelsen er bunnoppvarmingen (E2) ved rektifikasjonsfraskillelsen (M) av metan forbundet via et C3-kjølekretsløp (V4, E4, E5, 20-27) med toppkjølingen (E3) ved rektifikasjonsfraskillelsen (E) av C2, C2/C02, C2+ eller C3+.A process for separating a C2, C2 / CO2, C2 + or C3 + rich fraction from a hydrocarbon rich fraction, wherein the hydrocarbon rich fraction is pressure relieved in one or more steps and subjected to rectification to separate from methane. The methane-poor fraction obtained by separating from methane is subjected to separation by C2, C2 / CO2, C2 + or C3 + by rectification. According to the invention, the bottom heating (E2) at the rectification separation (M) of methane is connected via a C3 cooling circuit (V4, E4, E5, 20-27) to the top cooling (E3) at the rectification separation (E) of C2, C2 / CO2, C2 + or C3 +.
