A dividing wall distillation column is in fluid communication with the transalkylation effluent conduit, the alkylation effluent conduit, a product stream, a bottoms stream conduit and first and second benzene recycle conduits.

Abstract: This cumene process involves contacting, in an alkylation zone, a first benzene recycle stream and a propylene feed stream with an alkylation catalyst to form cumene. In a transalkylation zone, a polyisopropylbenzene recycle stream and a second benzene recycle stream are contacted with a transalkylation catalyst to form additional cumene. The effluents are passed into a benzene distillation column. From the benzene distillation column, a first benzene recycle stream is removed as overhead; a second benzene recycle stream is removed as a side draw; and a bottoms stream comprising polyisopropylbenzene, cumene, and heavy aromatics is removed from an end. The bottoms stream is passed to a dividing wall distillation column where the polyisopropylbenzene recycle stream is removed from an intermediate point; a cumene product stream is removed from a first end, and a heavy aromatic stream is removed from a second end.

Abstract: This ethylbenzene process involves contacting, in an alkylation zone, a first benzene recycle stream and an ethylene feed stream with an alkylation catalyst to form ethylbenzene. In a transalkylation zone, a polyethylbenzene recycle stream and a second benzene recycle stream are contacted with a transalkylation catalyst to form additional ethylbenzene. The effluents are passed into a benzene distillation column. From the benzene distillation column, a first benzene recycle stream is removed as overhead; a second benzene recycle stream is removed as a side draw; and a bottoms stream comprising polyethylbenzene, ethylbenzene, and flux oil is removed from an end. The bottoms stream is passed to a dividing wall distillation column where the polyethylbenzene recycle stream is removed from an intermediate point; an ethylbenzene product stream is removed from a first end, and a heavy oil stream is removed from a second end.

Abstract: A process for the removal of sulfur-oxidated compounds from a hydrocarbonaceous stream containing sulfur-oxidated compounds wherein the hydrocarbonaceous stream containing sulfur-oxidated compounds is contacted with an adsorbent which selectively adsorbs sulfur-oxidated compounds from the hydrocarbonaceous stream to produce an adsorbent having adsorbed sulfur-oxidated compounds. The loaded adsorbent containing sulfur-oxidated compounds is contacted with a desorbent to produce a desorbent containing sulfur-oxidated compounds and an adsorbent having a reduced content of sulfur-oxidated compounds. The regenerated adsorbent is then used to remove additional sulfur-oxidated compounds.

Abstract: A dummy body for testing of sitting, reclining and supporting cushions of upholstered sitting and reclining furniture, by means of which a complex interaction of various muscles can be simulated, true to reality, in a variable way, and which is distinguished by a cost-effective and simple construction. The worn parts can be replaced quickly and cost-effectively. The dummy body has a plurality of discs arranged adjustably next to one another and having different material properties in terms of the degree of hardness. Therefore, the muscle hardness of a dummy body to be simulated can be set variably according to a predetermined test program.

Abstract: A three-phase liquid polishing and cleaning composition of the invention is suitable for polishing and cleaning a painted exterior surface, and includes an organic phase, an aqueous phase, and a particulate phase. The organic phase comprises a petroleum-based liquid and the aqueous phase comprises water. The particulate phase comprises at least one particulate polishing grade abrasive having a mean particle size of not more than about 2.5 microns, which is selected from the group consisting of an abrasive that is harder than the painted surface to be polished and cleaned, and an abrasive that is softer than the painted surface to be polished and cleaned. The composition comprises at least one surfactant (e.g., an anionic surfactant, an emulsifying agent, and a foaming agent) to emulsify the organic and aqueous phases upon mixing (e.g., shaking) the composition, and to suspend the particulate phase in the emulsified organic and aqueous phases.

Abstract: An improved process and system for the endothermic dehydrogenation of an alkane stream is described. The process and system of the present invention comprise a back-mixed fluidized bed reactor. The alkane stream is dehydrogenated in a single reactor stage by contacting the alkane stream with a back-mixed fluidized bed of catalyst. Deactivated catalyst is withdrawn from the back-mixed fluidized reactor and heated to produce hot regenerated catalyst. The hot regenerated catalyst is returned to the back-mixed fluidized bed reactor at a rate sufficient to maintain the back-mixed fluidized bed reactor at substantially isothermal conditions.

Abstract: In processes for recovering one or more xylene isomers and isomerizing the remaining isomers for recycle, the isomerate is distilled to provide a toluene-containing overhead, a mid-boiling fraction containing C8 aromatics and a bottoms fraction containing C8 aromatics and C9+ aromatics. The mid-boiling fraction is recycled to the unit for recovering the sought xylene isomers and has sufficiently low content of C9+ aromatics that the separation feed to the unit for recovering the sought xylene isomers contains up to about 500 ppm-mass C9+ aromatics. The processes provide a high quality xylene isomer product while achieving at least one of debottlenecking, energy savings and capital savings.

Abstract: Processing schemes and arrangements for application of a dividing wall separation column in the processing of an effluent resulting from FCC processing modified for increased light olefin production.

Corresponding or associated processing schemes and arrangements for the catalytic cracking of a heavy hydrocarbon feedstock and obtaining light olefins substantially free of carbon dioxide via absorption-based product recovery are also provided.

Abstract: An integrated web browser, instant messaging system is presented. The system operates on mobile devices and other types of embedded devices. The system is an integrated instant messaging and web browsing application controlled by an embedded application on a mobile device. Today most web browsers, instant messaging, and other programs are separate or discrete applications that are executed on an either/or type of situation. The present system provides an integrated application environment that is a single application that shares data between instant messaging and web broswer sub-modules, which allows users to simultaneously message and browse. The system may also be deployed as part of an overall method for enhancing safety and producing revenue for communications networks.

Abstract: A control apparatus and control method for controlling the separation in a dividing wall distillation column of at least two feeds into at least three products is disclosed. The apparatus uses a temperature measuring device to measure the temperature of fluid in the column, a controller, and a means for adjusting the temperature of fluid in the column. The temperature measuring device may be on either side of the dividing wall or above or below the dividing wall, and more than one such device may be used. The apparatus and method may be used in the production of alkylaromatic hydrocarbons by alkylating aromatic hydrocarbons with olefinic hydrocarbons.

Abstract: A warm-air furnace is adapted to provide diagnostic enhancements and more robust installation. In an embodiment, sensing equipment aboard the furnace is used to determine a first performance metric during installation of the furnace. That performance metric is then compared with a baseline metric that may have been obtained at a factory in order to obtain a performance variation value. At least partially in response to the performance variation, a notification is provided to a user. The notification may be an indication of poor installation or shipping damage, present failure and/or predicted future failure, for instance.
