This disclosure provides an apparatus and method for harnessing machine learning and data analytics for a real-time predictive model for a FCC pre-treatment unit. The method includes collecting operating parameters of a pre-treatment unit and fluid catalytic cracking (FCC) unit; evaluating an independent variable of the operating parameters; and adjusting an input to the pre-treatment unit to control the independent variable within specifications in an output of the FCC unit.

An integrated process for maximizing recovery of aromatics is provided. The process comprises passing at least a portion of a xylene column bottoms stream to a heavy aromatics column to provide a heavy aromatics column bottoms stream comprising Caromatics and a heavy aromatics column overhead stream. The heavy aromatics column bottoms stream is passed to a second stage hydrocracking reactor of a two-stage hydrocracking reactor. In the second stage hydrocracking reactor, the heavy aromatics column bottoms stream is hydrocracked in the presence of a hydrocracking catalyst and hydrogen to provide a hydrocracked effluent stream.

An integrated process for maximizing recovery of hydrogen is provided. The process comprises: providing a hydrocarbonaceous feed comprising naphtha, and a hydrogen stream to a reforming zone, wherein the hydrogen stream is obtained from at least one of a hydrocracking zone, a transalkylation zone, and an isomerization zone. The hydrocarbonaceous feed is reformed in the reforming zone in the presence of the hydrogen stream and a reforming catalyst to provide a reformate effluent stream. At least a portion of the reformate effluent stream is passed to a debutanizer column of the reforming zone to provide a net hydrogen stream and a fraction comprising liquid petroleum gas (LPG). At least a portion of the net hydrogen stream is recycled to the reforming zone as the hydrogen stream.

An integrated process for maximizing recovery of LPG is provided. The process comprises providing a hydrocarbonaceous feed comprising naphtha, and a hydrogen stream to a reforming zone. The hydrocarbonaceous feed is reformed in the reforming zone in the presence of the hydrogen stream and a reforming catalyst to provide a reformate effluent stream. At least a portion of the reformate effluent stream and at least one stream comprising Chydrocarbons from one or more of a hydrocracking zone, an isomerization zone, and a transalkylation zone is passed to a debutanizer column of the reforming zone to provide a fraction comprising liquid petroleum gas (LPG) and a debutanizer column bottoms stream.

Processes for the production of a gasoline blend. A Cportion of a naphtha stream is first isomerized to increase the branched, iso-paraffins, and then, the isomerized effluent is passed to a dehydrogenation reaction zone. In the dehydrogenation zone, the Csaturated hydrocarbons are convert to Colefins. The Colefins have a higher octane number than the Csaturated hydrocarbons, and the branched olefins have a higher octane number than the normal olefins. The Colefins can be blended in a gasoline pool. Cand Chydrocarbons can be isomerized and dehydrogenated as well, separately or with the Ccomponents.

A process and apparatus for reducing the sulfur content of naphtha. The process includes introducing at least a portion of a naphtha feed stream to a selective hydrodesulfurization zone under selective hydrodesulfurization conditions in the presence of a selective hydrodesulfurization catalyst to form a low sulfur stream which contains mercaptan and thiophene compounds. At least a portion of the low sulfur stream is separated into at least two streams, a mercaptan rich stream containing mercaptan and thiophene compounds and an overhead stream containing hydrogen sulfide and liquid petroleum gas. The mercaptan rich stream is treated in an adsorbent zone to remove at least a portion of the mercaptan and thiophene compounds to form a mercaptan lean stream.

Removal of sulfur from naphtha

A process for hydrotreating full range naphtha is disclosed including the steps of passing a vapor stream composed of naphtha hydrocarbons to a first catalyst bed of a hydrotreating reactor, passing a liquid stream composed of naphtha hydrocarbons to a second catalyst bed of the hydrotreating reactor, and recovering a hydrotreated product stream from the hydrotreating reactor. The first and second catalyst beds are arranged in series within the hydrotreating reactor, and the second catalyst bed is downstream of the first catalyst bed.

A process for recovery of sulfolane used in a solvent-extraction or extractive-distillation process includes introducing a mixture into a solvent-recovery column having a heat source connected to a bottom portion of the column and removing a lean solvent stream, substantially free of hydrocarbons, from the bottom of the column, removing a polar-hydrocarbon-rich overhead stream from the top section of the column and maintaining the needed vacuum conditions using a liquid-jet ejector, preferably using water as the liquid.

Aromatics-recovery process

The present invention comprises a process for recovery of sulfolane used in a solvent-extraction or extractive-distillation process. A recovery column for the sulfolane solvent comprises a liquid-jet ejector for maintaining the needed vacuum conditions, preferably using water as the liquid.
