Abstract

A találmány tárgya eljárás C2- vagy C2+-szénhidrogének leválasztásárakönnyű szénhidrogéneket és adott esetben metánnál könnyebben forrókomponenseket tartalmazó gázáramból, amelynek során a megnövelt nyomásalatt álló gázáramot lehűtik, parciálisan kondenzálják és egy elsőszétválasztófokozatban egy folyékony és egy gáznemű frakcióraszétválasztják, és a folyékony frakciót egy másodikszétválasztófokozatban rektifikáció útján egy, lényegében C2- vagyC2+-szénhidrogéneket tartalmazó termékáramra és egy, túlnyomó részbenkönnyebben forró komponenseket tartalmazó maradék gázáramraszétbontják, ahol a parciális kondenzálás után keletkező gázneműfrakciót az első szétválasztófokozatból egy harmadikszétválasztófokozatban rektifikációsan egy folyékony és egy gázneműfrakcióra bontják szét. A folyékony frakciót visszavezetett áramként amásodik szétválasztófokozatba vezetik, ahol a találmány szerint azutolsóként említett folyékony frakciót (6') visszavezetett áramként arektifikálóan ható első szétválasztófokozatba (T1) vezetik. Atalálmány tárgya továbbá berendezés az eljárás foganatosítására. Ó
