摘要 |
Process and plant for recovering liquid hydrocarbons from a gaseous feedstock. …<??>This plant comprises essentially: a compressor for compressing the gaseous feedstock (C1), an absorption column (A1) for C5 and heavier hydrocarbons, which is associated with a debutanisation column (D1), an absorption column (A2) for C3 and heavier hydrocarbons, which is associated with a deethanisation column (D2) and with a heat exchange system (SE) connected to a refrigeration circuit. …<??>This plant makes it possible to obtain from a gaseous feedstock originating from a catalytic cracking unit a debutanised petrol (21), a liquefied gas cut (C3 and C4 hydrocarbons) and a gas cut (C2 hydrocarbons and lighter gases) in which the losses of C3 and higher hydrocarbons are much smaller than those obtained with the present plants. …<IMAGE>… |
