Abstract: The present invention is related to the isomerization process in which a light naphtha stream comprising of paraffinic (mono and single branched), naphthenic and aromatic hydrocarbons in the range of C5-C7 is contacted with the solid catalyst in multiple reaction zones and in presence of hydrogen to produce high octane gasoline predominantly comprising of paraffins (single and di-branched) and naphthenes. The process scheme comprises of more than one isomerization reaction section operating at different temperatures and other operating conditions. The catalyst employed in these reaction sections is a high coordination sulfated mixed metal oxide catalyst which contains at least one noble metal and sulfated zirconia in addition to the other components. The process of the present invention also comprises more than one fractionation section and recycling of a particular stream to the reaction zone for improving the isomerization of light naphtha.

Abstract: The present invention utilizes mechanical vapor compression and/or thermal vapor compression integrating compression loops across multiple process stages. A sequential network of compressors is utilized to increase the pressure and condensing temperature of the vapors within each process stage, as intra-vapor flow, and branching between process stages, as inter-vapor flow. Because the vapors available are shared among and between compressor stages, the number of compressors can be reduced, improving economics. Balancing vapor mass flow through incremental compressor stages which traverse multiple process stages by splitting vapors between compressor stages enables the overall vapor-compression system to be tailored to individual process energy requirements and to accommodate dynamic fluctuations in process conditions.

Abstract: Methods for operating a system having two downflow high-severity FCC units for producing products from a hydrocarbon feed includes introducing the hydrocarbon feed to a feed separator and separating it into a lesser boiling point fraction and a greater boiling point fraction. The greater boiling point fraction is passed to the first FCC unit and cracked in the presence of a first catalyst at 500° C. to 700° C. to produce a first cracking reaction product and a spent first catalyst. The lesser boiling point fraction is passed to the second FCC unit and cracked in the presence of a second catalyst at 500° C. to 700° C. to produce a second cracking reaction product and a spent second catalyst. At least a portion of the spent first catalyst or the spent second catalyst is passed back to the first FCC unit, the second FCC unit or both.

Abstract: This disclosure provides systems and methods that utilize integrated mechanical vapor or thermal vapor compression to upgrade process vapors and condense them to recover the heat of condensation across multiple processes, wherein the total process energy is reduced. Existing processes that are unable to recover the heat of condensation in vapors are integrated with mechanical or thermal compressors that raise vapor pressures and temperatures sufficient to permit reuse. Integrating multiple processes permits vapor upgrading that can selectively optimize energy efficiency, environmental sustainability, process economics, or a prioritized blend of such goals. Mechanical or thermal vapor compression also alters the type of energy required in industrial processes, favoring electro-mechanical energy which can be supplied from low-carbon, renewable sources rather than combustion of carbonaceous fuels.

Abstract: Systems and methods are provided for reducing or minimizing fouling within the primary fractionator of a pyrolysis reaction system. The reduced or minimized fouling can be achieved in part by providing one or more pump-around trays in the primary fractionator below the level of the fractionation trays for an intermediate product produced by the fractionator. Including a pump-around section below the fractionation trays can improve vapor distribution within the fractionation trays, which are believed to have an increased likelihood of accumulation of foulant deposits. Optionally, other vapor distribution devices can be included along with the pump-around section.

Abstract: Distillate boiling range and/or diesel boiling range compositions are provided that are formed from crude oils with unexpected combinations of high naphthenes to aromatics weight and/or volume ratio and a low sulfur content. This unexpected combination of properties is characteristic of crude oils that can be fractionated to form distillate/diesel boiling range compositions that can be used as fuels/fuel blending products with reduced or minimized processing. The resulting distillate boiling range fractions and/or diesel boiling range fractions can have an unexpected combination of a high naphthenes to aromatics weight and/or volume ratio, a low but substantial aromatics content, and a low sulfur content. By reducing, minimizing, or avoiding the amount of hydroprocessing needed to meet fuel and/or fuel blending product specifications, the fractions derived from the high naphthenes to aromatics ratio and low sulfur crudes can provide fuels and/or fuel blending products having a reduced or minimized carbon intensity.
