Abstract

Det er beskrevet en fremgangsmåte og anordning for fjerning av en forurensning fra en fluidfødestrøm som inneholder forurensningen. Fremgangsmåten omfatter trinnene med tilføring av en fødestrøm (10) og oppvarming av denne i et første trinn (18) for i det minste delvis å fjerne noen av forurensningene og gjen- vinne energi fra et konstentrat og et destillat som genereres. Ytterligere oppvarming av fødestrømmen i et andre oppvarmingstrinn (20) i en oppvarmet separator genererer en mettet dampfraksjon (30) og en konsentrert forurenset væske- fraksjon. Dampfraksjonen (30) kan kompri- meres for å generere en temperatur- forskjell i kokeren (34) med anbringelse av dampfraksjonen i kontakt med en koker (eng. :.. "reboiler exchanger") (34) for å danne en strøm av konendsert damp fra kokeren. Dampen kan sirkuleres gjennom kokeren (34) og den oppvarmete separatoren for å opprettholde fra omlag 1% til omlag 50% av massen som damp i strømmen. Anordningen omfatter en unik konfigurering av en dampkompressor, oppvarmet separator i kombinasjon med en tvungen sirkulasjons- krets (42,44,38) for å generere renset resultat.
