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).A process for liquefying a hydrocarbon-rich stream, in particular a natural gas stream, wherein the hydrocarbon-rich stream is liquefied in heat exchange with at least one refrigerant circuit and / or at least one refrigerant mixture circuit, and the method of liquefaction comprises at least one additional process step in addition to the process stage "liquefaction". that upon starting the liquefaction process, a hydrocarbon-rich foreign fraction (12) is at least temporarily supplied before the first process step (A), the plant parts of the individual process steps (AH) to be dried and / or cooled are dried and / or cooled at by means of the hydrocarbon-rich foreign fraction, and the individual process steps (AH) are then put into operation, and the hydrocarbon-rich foreign fraction sent through the individual process steps (AH) is fed back before the first process step (A).
