Abstract

Fremgangsmåte for flytendegjøring av en hydrokarbonrik strømning, særlig en naturgasstrømning, hvor den hydrokarbonrike strømning blir flytendegjort i varmneveksling med minst én kjølemiddelkrets og/eller minst én kjølemiddelblandingskrets, og fremgangsmåten for flytendegjøring omfatter minst ett ytterligere prosesstrinn i tillegg til prosesstrinnet "flytendegjøring", kjennetegnet ved at ved oppstarting av fremgangsmåten for flytendegjøring blir en hydrokarbonrik fremmed fraksjon (12) i det minste midlertidig tilført før det første prosesstrinn (A), anleggsdelene i de individuelle prosesstrinn (A-H) som skal tørkes og/eller kjøles blir tørket og/eller kjølt ved hjelp av den hydrokarbonrike fremmede fraksjon, og de individuelle prosesstrinn (A-H) blir deretter satt i drift, og den hydrokarbonrike fremmede fraksjon som er sent gjennom de individuelle prosesstrinn (A-H) mates tilbake før det første prosesstrinn (A).
