Process scheme configurations are disclosed that enable conversion of crude oil feeds with several processing units in an integrated manner into petrochemicals. The designs utilize minimum capital expenditures to prepare suitable feedstocks for the steam cracker complex. The integrated process for converting crude oil to petrochemical products including olefins and aromatics, and fuel products, includes mixed feed steam cracking and gas oil steam cracking. Feeds to the mixed feed steam cracker include one or more naphtha fractions from hydroprocessing zones within the battery limits, including vacuum residue hydrocracking, within the battery limits, recycle streams from the C3 and C4 olefins recovery steps, and raffinate from a pyrolysis gasoline aromatics extraction zone within the battery limits. Feed to the gas oil steam cracker in certain embodiments includes gas oil range intermediates from the vacuum residue hydrocracking zone. In addition, a base oil production center is integrated to provide base oils product used for production of synthetic lubes or corresponding lube oil feedstocks

The invention is an integrated process for treating residual oil of a hydrocarbon feedstock. The oil is first subjected to solvent deasphalting then gas phase oxidative desulfurization. Additional, optional steps including hydrodesulfurization, and hydrocracking, may also be incorporated into the integrated process.

The present invention provides a catalytic gasoline desulfurization method having also an olefin selective removal function, which comprises: when a catalytic gasoline is pre-hydrotreated, cutting into a light fraction, a middle fraction and a heavy fraction; performing liquid-liquid extraction desulfurization treatment on the middle fraction to produce a sulfur-poor oil and a rich solvent containing sulfur-rich oil; the light fraction back-extracting the rich solvent, using C5 olefin therein to replace a macromolecular acyclic olefin in the sulfur-rich oil, so as to gather together C5 iso-olefins, cycloolefins, aromatic hydrocarbons and sulfides in the sulfur-rich oil; performing hydrogenation, olefin-reduction and desulfurization treatment on the heavy fraction together with the sulfur-rich oil removed from the back-extracted rich solvent to saturate the olefin therein; and finally, preparing together with the sulfur-poor oil to produce a full range gasoline. The sulfur-content of the catalytic gasoline produced by the method of the present invention can be reduced to 10 ppm or less, the olefin content of the catalytic gasoline can be reduced to 22%, the olefin is saturated by up to 8 percentage, and the RON loss of the full range gasoline is 1.5 or less, so that while reducing the olefin content of the catalytic gasoline, it ensures the less octane number loss, thereby satisfying the olefin-reduction requirements upgraded in the gasoline National VI Standard for ethanol-gasoline supply area enterprises.

The present invention provides a method and apparatus for processing to improve the properties of pyrolysis oil and, as a result, the commercial value of the same. The net result is creation of an oil with a much lighter color in lieu of the black color, reducing or elimination the undesired sulfury/amine aroma and reducing the amount of PAH which is believed to be a carcinogen.
