摘要： An FCC process 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 method of heating or cooling particulate material by indirect heat exchange of the particles with the heat exchange fluid in a heat exchanger located outside and offset from the vessel that supplies the particulate material and to which the particulate material returns uses the addition of an open conduit to increase catalyst circulation through the heat exchanger. The open conduit has been found to be effective when used internally or externally. The internal use of the open conduit minimizes structural changes required to retrofit the conduit to existing back mix coolers. The use of the conduit for increased catalyst circulation allows a flow through type cooler duty to be produced in an amount of space that would ordinarily only permit the use of a backmix type cooler.

摘要： A method and apparatus for cooling hot FCC catalyst particles in a heat exchange zone that is separate and distinct from the regenerator having an upper portion that operates in a flow-through mode and a lower part that operates in a back mix mode. Catalyst descends from a collection zone into an upper inlet of a heater exchanger. The exchanger contains a series of tubes for indirect heat exchange of the catalyst with a cooling fluid. Catalyst leaves the exchanger through an outlet located at a mid portion of the exchanger. The section of the exchanger between the inlet and outlet comprises the flow-through portion. Catalyst undergoes further heat exchange below the outlet of the exchanger in the backmix portion. Fluidizing gas that enters at the bottom of the exchanger provides the necessary turbulence for particle interchange in the backmix section of the heat exchange zone as well as transport of the particulate material through the flow-through portion of the exchanger. The method and exchanger design facilitates the addition of surface area to the exchanger and increases the heat removal duty in the backmix section of the exchanger.

摘要： A method and apparatus for an FCC process uses dissipator plates at the outlet of a disengaging vessel to provide a quick separation of catalyst from product vapors and to prevent reentrainment of catalyst into the disengaging vessel. The process and apparatus use a riser for the conversion of an FCC feedstock and direct the effluent from the riser directly into a disengaging vessel to separate catalyst from the product vapors. Catalyst is directed downwardly out of the outlet of the disengaging vessel and through a series of dissipator plates that eliminate the tangential velocity that would be otherwise introduced by the vortex and would lead to reentrainment of catalyst. A stripping vessel is located immediately below the disengaging vessel outlet to receive catalyst as it leaves the dissipator plates. The apparatus and process are specifically suited for operation without a reactor vessel for containment of the disengaging vessel and cyclones.

摘要： A method of converting a side by side FCC arrangement adds a new reactor vessel and uses the regenerator vessel and reactor vessel to provide a regeneration section having at least three stages of regeneration that is used as part of an enlarged FCC process. In simplest form, the conversion method calls for the use of the regeneration vessel as a first-stage regeneration zone, the use of the reactor vessel as a second-stage regeneration zone, and the use of the spent catalyst stripper as a third stage of regeneration. This arrangement provides a second stage of regeneration that is positioned to facilitate the addition of partially regenerated catalyst to the stripping zone to facilitate the operation of a hot catalyst stripping section.

摘要： This invention provides an improved method for stripping hydrocarbons from spent catalyst which has been used in effecting hydrocarbon conversion reactions prior to the regeneration of this catalyst by combustion of carbon deposits upon the catalyst. The invention is described in terms of its use in FCC processes, since such processes are the most common application of the invention. In order to better distribute stripping gas, which is normally steam, so that the gas contacts and passes through substantially all of the catalyst, distribution ports are added to the skirts of the stripper baffles which direct catalyst flow in a generally side-to-side manner as it moves downward through a stripping vessel. The ports are sized to vary penetration of the stripping gas into the stream catalyst that moves past the grids. Use of these ports increases the amount of hydrocarbons removed from the spent catalyst and/or decreases stripping gas requirements.

摘要： An arrangement for the controlled production of an essentially linear array of hydrocarbon feed injection jets reduces required clearances and elevation while facilitating modification of the contacting locating a feed distributor containing a linear array of jets at a standpipe junction point to provide choke point for particle flow control. The flow properties of the extended particle layer are controlled by adjusting the density of the particles above the choke point created by the upper part of the standpipe inside diameter and the top of the distributor. Steam or another fluidization medium may be added to the particles directly above the distributor for this purpose. This invention can also modify the particle or feed injection characteristics by changing the projection of the distributor into the standpipe to adjust the flow area over the choke point and by the use of bottom slides or baffles to change the flow area size and configuration. Location of the distributor at a standpipe junction will also typically allow the placement of the distributor at a lower location in the process which eliminates the need to add vessel height for supplying pressure drop for the particle discharge point. The distributor arrangement also fits compactly into most common standpipe junctions. Thus, the arrangement of this invention solves the problem of inserting an extended array of feed injection points into a fluidized particle contacting process without providing a large amount of clearance or additional vessel height.
摘要翻译： 用于控制生产基本上线性的烃类进料喷射喷嘴的装置减少了所需的间隙和高度，同时促进了在竖管连接点处定位含有线性阵列阵列的进料分配器的接触的修改，以提供用于颗粒流控制的阻塞点 。 扩展颗粒层的流动特性通过调节由竖管内部直径的上部和分配器的顶部产生的阻塞点之上的颗粒的密度来控制。 为此目的，可以将蒸汽或另一种流化介质加入分布器正上方的颗粒。 本发明还可以通过改变分配器到立管中的投影来调整颗粒或进料注入特性，以调节阻塞点上的流动面积，并且通过使用底部滑块或挡板来改变流动面积的大小和构型。 分配器在立管接头处的位置通常还允许将分配器放置在该过程中的较低位置处，这消除了增加用于为颗粒排放点提供压降的容器高度的需要。 分配器安排也紧凑地配合到大多数常见的立管接头中。 因此，本发明的装置解决了将延伸的进料喷射点阵列插入到流化颗粒接触过程中而不提供大量间隙或另外的容器高度的问题。

摘要： This FCC process suspends a layer of catalyst in a riser proximate or above the riser outlets. The density at the riser outlets is higher than the flowing density in the riser. The suspended catalyst provides a disengagement zone that enhances the separation of catalyst from product vapors. The riser operates in a manner that prevents any discharge of catalyst from its end. The arrangement also provides a convenient method for vetoing stripping vapors into a closed reactor cyclone system.

摘要： An FCC reactor achieves greater utilization of the space within the reactor vessel by using a vented riser arrangement having an inlet opening at the bottom of a vented riser collector. The inlet opening at the bottom of the vented riser collector allows plug flow of the catalyst and hydrocarbon vapors through the upper and lower section of the reactor vessel without any substantial degradation and separation efficiency between the catalyst and the hydrocarbon vapors. This permits almost the entire tangent length of the reactor vessel to be used for the purpose of catalyst and hydrocarbon contact.

摘要： The liquid feed injector as hereindescribed uses sequential stages of increased severity mixing to fully atomize a liquid portion of a combined liquid and gaseous stream. Sequential mixing consists of a first mild mixing that takes place in a mild mixing zone and blends the liquid and gaseous material into a substantial uniform mixture. The uniform mixture of liquid and gaseous material passes through another stage of vigorous mixing where the liquid is sheared and gas is dispersed throughout the liquid by dividing the mixture into a plurality of small streams and directing the projection of the streams into impingement with an impact medium to produce a homogeneous mixture of fine gas bubbles dispersed in the liquid. The homogeneous liquid and gas mixtures are then discharged through one or more discharge nozzles to effect atomization and distribution of the liquid in a suspension of fluidized solids. The sequential stages of increased severity mixing allow atomization of the liquid into fine droplets with a reduced pressure drop across the discharge nozzles. In a highly preferred form, the liquid injector includes provisions for injecting two fluid streams into a suspension of fluidized solids at two discrete locations.
