Abstract

Et NGL-gjenvinningsanlegg med to tårn innbefatter en absorbator (110) og et destillasjonstårn (140) i hvilket absorbatoren (110) mottar to avkjølte refluks-strømmer, hvor én refluksstrøm (107) omfatter den dampandel av naturgasskondensatet (NGL), og hvor den andre refluksstrømmen (146) omfatter en mager refluks tilveiebrakt av den overliggende delen (144) av destillasjonstårnet (140). Tenkte utførelsesformer er spesielt fordelaktige ved en omgradering av eksisterende NGL-anlegg og oppvinner typisk C3-gjenvinning på minst 99% Og C2-gjenvinning på minst 90%.
