A process for producing aromatics from a hydrocarbon source in the presence of supercritical water comprising the steps of mixing a pressurized, pre-heated water stream with a pressurized, pre-heated petroleum feedstock, the pressurized, pre-heated water stream at a pressure above the critical pressure of water and a temperature above the critical temperature of water, feeding the combined stream to a supercritical water reactor to create a modified stream, cooling and depressurizing the modified stream, separating the depressurized stream in a vapor-liquid separator, condensing the vapor stream, separating the condensed stream into a water recovery stream and a light product recovery stream, extracting the aromatics from the light product recovery stream, depressurizing the liquid stream, separating the depressurized liquid stream in a heavy separator into an upgraded product stream, and recycling part of the upgraded product stream to the pressurized, pre-heated petroleum feedstock as a product recycle.

Process to produce aromatics from crude oil

A method and apparatus for separating mercury and other undesired constituents from a natural gas stream includes passing the raw gas stream sequentially through a first separator, an amine treatment unit, a cooler, a second separator, a dehydrator, a cooler and a third separator. The first separator receives the natural gas stream and separates hydrocarbon and water condensates from the stream; the amine treatment unit removes acid gases; the cooler reduces the temperature of the gas stream to condense additional hydrocarbons and water that are removed by the second separator; and the dehydrator removes water vapor. Next, the temperature of the stream is reduced by the second cooler to condense the mercury and any remaining hydrocarbon vapors. The third separator includes a vessel having a gas inlet and outlet for discharging processed gas, a deflector disposed proximate the inlet for deflecting mercury and other condensates in the gas stream and a mercury trap disposed at the bottom of the vessel to collect the mercury.
