    摘要： A splitter system is disclosed that produces a product stream from a mixed stream of two materials with similar boiling points. A multi-stage heat pump compressor is used in combination with a bottoms reboiler and an intermediate reboiler resulting in reduced utility consumption. The appropriately placed intermediate reboiler enables use of a lower temperature heat source relative to the bottoms reboiler heat source. As a result, a lower pressure overhead vapor stream can be used to deliver heat to both the intermediate and bottoms reboilers, thereby conserving energy. The first stage of the multi-stage heat pump compressor delivers pressurized overhead vapor to the intermediate reboiler and the second stage provides pressurized overhead vapor to the bottoms reboiler. The disclosed design and method lessens the heat pump compressor power consumption and trim condenser duty for a propylene/propane splitter system by over 20%. A third stage of compression upstream of the overhead trim condenser may be used for purposes of making the column pressure and temperatures independent of the trim condenser temperature.

    摘要： Disclosed is a mixer-distributor-collector apparatus for use between beds of solid particles in a fluid-solid contacting vessel. The apparatus includes a solids retaining screen, fluid deflector, passageway, fluid distributor, and flow manipulator. The flow manipulator is a device such as a honeycomb, porous solid, perforated plate, screen, or grid having an open area greater than the open area of the fluid distributor and is located below and spaced apart from the fluid distributor. The apparatus improves the fluid flow characteristics by minimizing or eliminating fluid velocity jets and/or other turbulence which can disturb the downstream particle bed. In an exemplary application, the invention finds use in simulated moving bed (SMB) adsorptive separation processes.

    摘要： A method and apparatus for alkylating an alkylation substrate with an alkylating agent in the presence of solid catalyst particles in a transport reactor is disclosed. Solid catalyst particles in the transport reactor effluent recirculate to the inlet of the transport reactor through one or more conduits. The rate through each conduit is regulated by fluid-controlled valves that use the alkylation substrate as the regulating fluid. This method and apparatus help ensure uniform or symmetric flow of catalyst from the effluent of the transport reactor to the bottom of the transport reactor. This method and apparatus also help ensure uniform or symmetric flow of alkylation substrate to the bottom of the transport reactor with minimal bypassing by the alkylating agent around of the transport reactor. This invention finds use in the production of motor fuels by the alkylation of liquid hydrocarbons in the presence of solid catalyst particles.

    摘要： A method is disclosed for recovering chlorine-containing species from an outlet stream of a zone in which the catalytic metal of a chloride-containing catalyst is reduced. The outlet stream is passed to a sorption zone which contains catalyst and which is maintained at sorption conditions. The catalyst in the sorption zone sorbs the chlorine-containing species from the outlet stream. This method captures and retains within the process the chlorine-containing species that would otherwise be lost from the process and that would need to be replaced by the injection of make-up chlorine-containing species. This method results in a significant savings in capital and operating costs of a catalyst regeneration process that includes a reduction step. This method is adaptable to many catalytic hydrocarbon conversion processes which pass catalyst particles between or among moving bed reaction and regeneration zones.

    摘要： A process for the continuous oligomerization of ethylene to produce linear alpha olefins by oligomerizing ethylene in a polar phase comprising a solution of transition metal catalyst system at oligomerization conditions including a temperature and pressure greater than the critical temperature and pressure of ethylene. The resulting hydrocarbon phase containing oligomers and unreacted ethylene is subjected to physical treatment which tends to render the ethylene a nonsolvent for oligomers and thereby produce a liquid stream rich in unreacted ethylene which may be recycled to the oligomerization reaction zone by pumping.

    摘要： A vessel arrangement and process for contacting a fluid reactant with a particulate catalyst in a plurality of flow channels and discharging fluid and particles from the flow channels. The particles are discharged axially from the bottom of the flow channels into an unconfined bed of particles. Fluid is discharged in a transverse direction through the sides of the flow channels and across screen openings located a short distance above the channel outlets. A plurality of chambers, additional particulate material or baffles regulate fluid flow through sections of the screens and prevent excessive fluid velocity in any section from holding up particle flow through the flow channels. The reactor arrangement and process of this invention is a particularly useful for arrangements that may be used to operate a reactor under isothermal or other controlled temperature conditions where a heat transfer fluid surrounds a plurality of tubular conduits or multiple flow channels that confine the particles and fluid.
