摘要： A process for the removal of sulfur compounds and benzene of a catalytically cracked petroleum naphtha comprising benzene, organic sulfur compounds and olefins, by fractionating the cracked naphtha into a relatively low boiling range, olefinic, light catalytic naphtha (LCN) and an olefinic heavy catalytic naphtha (HCN) which boils above the range of the LCN the boiling ranges of the LCN and the HCN being defined by a cut point selected to maintain most of the benzene in the cracked naphtha in the LCN together with olefins in the boiling range of the LCN. The LCN is subjected to an optional non-hydrogenative desulfurization step followed by a fixed bed alkylation step in which the benzene in the LCN is alkylated with the olefins contained in this fraction. The HCN is treated by a similar an alkylation step using the olefins contained in this fraction to alkylate the sulfur compounds, forming alkylated products which boil above the gasoline boiling range. The LCN and HCN are then fractionated to remove light ends and higher boiling sulfur reaction products (disulfides, alkylated thiophenes) boiling above the gasoline boiling range.

摘要： A process unit for the zeolite-catalyzed conversion of light refinery olefins from an FCC unit such as ethylene, propylene, and butylene to gasoline boiling range motor fuels comprises at least two sequential, serially connected reactors connected in parallel to a fractionation section with at one or two fractionators for separating the reactor effluents into product fraction with an optional recycle stream or streams. The configurations according to this scheme allow the adjustment of reactor temperature and/or pressure and/or space velocity to be based on the reactivities of the olefin compounds present in the LPG streams so that the gasoline produced in each reactor will be separated immediately, to reduce over-polymerization of the gasoline in the low severity reactor and to ensure that gasoline formed in the low severity reactor will not be sent to the higher severity reactor e.g. with a higher reactor temperature, where excessive polymerization to undesirable higher molecular with products may take place.

摘要： A strainer device for a fluid flow circuit removes debris and solid particles from the fluid flow to prevent plugging and reduce fouling of the system. The assembly includes a chamber that can be hydrocyclonic, a collection area, a screen assembly and a distributor that allows selective connection to a flushing fluid. The fluid flows through the chamber past the strainer device, with large particles collecting in the collection area under the influence of gravity and smaller solid particles being collected in the screen assembly. Particles can be flushed from the system by selectively activating the distributor to back flush the screen assembly and sweep the collection area free of solid particles without disassembling the system.

摘要： A single path process for alkylating a hydrocarbon feedstock containing an olefin and an isoparaffin is disclosed. The process includes dispersing an acid-based liquid alkylation catalyst into a reaction zone for contact with a continuous hydrocarbon phase. The process further includes separating the hydrocarbon phase from the acid catalyst upon completion of the alkylation reaction and providing a continuous on-line regeneration of the entire volume of catalyst once it has been separated from the hydrocarbon phase.
