Abstract
In a crude oil purification process including phase separators, a vapor recovery unit (VRU), and dew pointing/dehydration and CO2 removal membranes, instead of compressing the low boiling point (i.e., C1-5) hydrocarbon vapor stream from the VRU along with the main portion of gas from the separation train and feeding it to the membranes, it is compressed and dehydrated along with the H2O/C3+ hydrocarbon enriched permeate from the dew pointing and dehydration membranes.
