METHOD FOR TREATING HYDROCARBONS

摘要

The invention relates to a method for treating hydrocarbons, said method including: providing an initial hydrocarbon stream including water; adding a liquid solvent into the initial hydrocarbon stream so as to provide an intermediate hydrocarbon stream, said liquid solvent containing a weight proportion of C3-C6 alkanes that is greater than or equal to 80%; gravitationally separating the intermediate hydrocarbon stream into an oleic phase and an aqueous phase; decompressing the oleic phase and separating the oleic phase into a gaseous hydrocarbon phase and a liquid hydrocarbon phase; recycling the gaseous hydrocarbon phase so as to at least partially provide the liquid solvent; and retrieving the liquid hydrocarbon phase. The invention also relates to a facility suitable for implementing said method.
