Abstract

Ved en fremgangsmåte til separering av hydrokarbonblandinger ved ekstraksjons- destillasjon blir der anvendt løsemidler som utmerker seg ved en høy selektivitet for den separasjon som skal utføres, og samtidig ved de anvendte konsentrasjons- og temperatur- betingelser danner områder uten blandbarhet med hydrokarbonene i utgangsproduktene. Stoffvekslerbetingelsene i ekstraksjons- destillasjonskolonnen blir herunder innstilt slik at der både mellom de to flytende faser innbyrdes og mellom disse og dampfasen fore- ligger store utvekslingsflater.
