A method of removing at least benzene from a hydrocarbon stream comprises concentrating aromatics in the hydrocarbon stream by passing the hydrocarbon stream through a membrane unit having at least one membrane to produce a permeate stream and a retentate stream, wherein the permeate stream is aromatics rich relative to the hydrocarbon stream; and extracting aromatics after concentrating using a selective aromatics extraction solvent in an extraction unit to produce an extract stream, wherein the extract stream is aromatics rich relative to the permeate stream.

Process for removing at least benzene from hydrocarbon streams

The present invention provides a method of removing contaminants from water which includes the steps of first providing a water feed exposed to at least one hydrocarbon or chemical process. This water feed is set in-line with a reverse osmosis system which includes an inlet, at least one reverse osmosis membrane, a permeate outlet, and a reject outlet. Then, pressure is applied to the water feed, or where the pressure of the water feed is higher than desired, the pressure is controlled or reduced. The pressure of the water feed serves to force the water feed through the reverse osmosis system. The reverse osmosis system then separates the water feed into a permeate and reject which includes at least one of the contaminants. The permeate is then directed to the permeate outlet and the reject is directed to the reject outlet.
