摘要： A process and apparatus is presented for the improved selectivity of oxygenate conversion to olefins. The process includes passing a process stream through a two stage reactor, wherein the process stream is separated from the catalyst in the first stage before passing the process stream to the second stage. The catalyst is continuously passed through the two stages, and cycles through a regeneration unit to control the carbon content on the catalyst.

摘要： A distillation column is disclosed. The column includes a plurality of rectification zones and corresponding stripping zones. Each rectification zone is linked to a heat pump or a stage of a heat pump. Overhead material from the top rectification zone is compressed and used to heat bottoms liquid from the bottom stripping zone. Similarly, overhead material from a lower rectification zone is compressed and used to heat liquid taken from the uppermost or top stripping zone. Optionally, overhead material from a middle rectification zone is compressed and used to heat liquid from a middle stripping zone. A single multiple stage heat pump compressor may be utilized as opposed to a plurality of heat pumps. Because the heat exchanger from each rectification-stripping zone pair has a lower duty, economical stab-in heat exchangers may be utilized.

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： Method and apparatus are provided for transferring particles from an upper zone through an intermediate zone to a lower zone. The transfer of particles between the zones through valveless conduits is regulated by varying the pressure of the intermediate zone and the flow rate of gas passing through the valveless conduits. A body within the lower zone is in particle communication with a valveless conduit and obstructs the particle flow within the lower zone.

摘要： One exemplary embodiment can include an apparatus for transferring catalyst from a regeneration zone to a reaction zone in a hydrocarbon conversion unit. The hydrocarbon conversion unit can include a transfer vessel, and first, second, and third lines. The transfer vessel can transfer regenerated catalyst from the regeneration zone at a first pressure to the reaction zone at a second pressure where the second pressure is greater than the first pressure. Generally, the first line communicates the catalyst to the transfer vessel and is coupled to a first valve to allow catalyst into the transfer vessel and the second line communicates the catalyst from the transfer vessel and is coupled to a second valve to allow catalyst out of the transfer vessel. The third line for allowing the passage of gas therethrough may be at a pressure higher than the first pressure having a first portion communicating with the transfer vessel and having a second portion coupled to third and fourth valves. Each of the third and fourth valves can have a first position that is open and a second position that is closed, which may correspond, respectively, to the opening and closing of the first and second valves to allow gas to pass therethrough.

摘要： Moving bed hydrocarbon conversion processes are provided for contacting a catalyst moving downward through a reaction zone with a hydrocarbon feed, withdrawing the catalyst from the reaction zone and conveying the catalyst to a regeneration zone wherein the catalyst moves downward. The catalyst is withdrawn from the regeneration zone and passed downward to an upper zone of a particle transfer apparatus wherein the transfer of catalyst from the upper zone through an intermediate zone to a lower zone is regulated by varying the pressure of the intermediate zone and the flow rate of gas passing through the valveless conduits. A container within the second zone is in catalyst communication with a valveless conduit and provides more consistent catalyst flows. The catalyst from the lower zone of the particle transfer apparatus is conveyed to the reactions zone.
