Abstract:
A method for the removal of entrained hydrocarbons, particularly aromatics, from water by extracting the hydrocarbons in the water with a hydrocarbon which is relatively less soluble in the water than the entrained hydrocarbon. The hydrocarbons are then separated from the water by a process of coalescence/separation. The extractant is suitably a paraffinic hydrocarbon which, while having an affinity for the entrained hydrocarbon, is relatively less soluble in water than hydrocarbons such as aromatics. The hydrocarbons removed from the water can be recirculated to the feed with the composition of the recirculating phase being controlled to achieve the desired level of hydrocarbon removal.
