ABSTRACT:
A method of and a plant for recovering liquid hydrocarbons in a gaseous batch, the plant comprising a compressor for the gaseous batch, a column for absorbing C5 and heavier hydrocarbons associated with a debutanization column; a column for absorbing C3 and heavier hydrocarbons associated with a de-ethanization column and with a heat exchange system connected to a refrigeration cycle, the plant providing from a gaseous batch issuing from a catalytic cracking unit a debutanized gasoline, a liquefied gas cut (C3 and C4-hydrocarbons) and a gaseous cut (C2 and lighter hydrocarbons) wherein the losses of C3 and higher C-hydrocarbons are much smaller than that occurring with existing plants.
