摘要： A novel cyclone is disclosed that is effective for separating, from a contaminated gas stream, solid particulates having diameters as low as 4 to 5 microns. When multiple cyclones of the present invention are affixed between upper and lower tube sheets in a separator device, fine particle removal is possible to the extent required 1) by stringent regulations governing particulate emissions into the atmosphere, or 2) to prevent damage to turbine blades in downstream power recovery equipment. The cyclones are especially relevant to the problem of removing catalyst fines from refinery effluents, most notably fluid catalytic cracking (FCC) regenerator flue gas. The cyclone separation efficiency is enhanced through the use of 1) a uni-directional flow of gas from the contaminated gas inlet to the clean gas outlet and 2) discharge openings on the surface of the cyclone body that allow ejection of solid particulates.

摘要： A process and apparatus is disclosed for heating or cooling polymer solids in a dispensing section of a solid-state polycondensation reactor. Gas is delivered to the dispensing section of the reactor in which it cools polymer solids in the dispensing section by direct heat exchange. Part of the gas is withdrawn at a point proximate to the dispensing section of the reactor and is cooled. The rest of the gas ascends through a reactive section of the reactor and purges polymer solids of impurities. The gas withdrawn from the reactive section of the reactor is oxidized of impurities and dried and then combined with the gas withdrawn proximate to the dispensing section of the reactor. To achieve uniform heating or cooling of the polymer solids in the dispensing section, a preferred ratio of mass flow rate of gas to the mass flow rate of solids is recommended.

摘要： A method is disclosed for recovering chlorine-containing species from the outlet gas of a hydrocarbon conversion process with a cyclic regeneration operation. The outlet gas from an off-stream catalyst bed in which regeneration is occurring is passed to another off-stream catalyst bed which contains spent catalyst and which is maintained at sorption conditions. The spent catalyst particles sorb the chlorine-containing species from the outlet gas. This method captures and retains within the hydrocarbon conversion process chlorine-containing species that would otherwise be scrubbed and lost from the process and that would need to be replaced by the injection of make-up chlorine-containing species. This method results in significant savings in operating costs of a cyclic regeneration process. This method is adaptable to many processes for the catalytic conversion of hydrocarbons in which deactivated catalyst are regenerated by a cyclic regeneration operation.

摘要： A method for replacing particles in a process that transfers particles is disclosed. This invention employs a seal zone which is in communication with two zones of the process and in which particles that are being added to the process are purged. This invention allows particles to be replaced without reducing the normal rate of particle transfer through the process, which results in a savings in downtime costs. This invention is adaptable to a multitude of processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated.

摘要： An FCC apparatus uses a highly efficient separation device to remove product from the catalyst so that the reactor vessel receives a low volume of feed hydrocarbons and riser by-products. The separation device encloses an upwardly directed outlet end of a ballistic separation device in low volume disengaging vessel that collects disengaged catalyst from the riser in a dense bed. Immediate contact of the dense bed with a stripping fluid minimizes the amount of hydrocarbons that are carried out of the disengaging vessel into the open volume of the reactor vessel.

摘要： A reactor arrangement and process for contacting a fluid reactant with a particulate catalyst in a plurality of flow channels and discharging converted reactant 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. Reactants are 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 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 particularly useful for arrangements that may be used to operate a reactor under isothermal or other controlled temperature controlled conditions where a heat transfer fluid surrounds a plurality of tubular conduits or multiple flow channels that confine the particles and reactants.

摘要： A regeneration process and apparatus eliminates the need for an external chlorination recycle loop. The method and apparatus uses two-pass internal mixing of a chlorine compound input stream and drying gas to both mix and heat the chlorination gas before entering the chlorination zone. The only heat required for the process is a small amount for vaporizing the chlorine containing input stream to prevent the formation of chloride droplets. All other heat for the chlorination zone is supplied internally in the regeneration vessel.
