摘要： A baffle-style stripping arrangement for an FCC process having substantially horizontal stripping baffles is disclosed. The stripping baffles comprise a perforated section and a downcomer section which generates transverse movement of catalyst across the baffle to ensure adequate vertical movement of stripping media. The perforated section is covered with stripping openings to provide improved stripping efficiency and catalyst flux through the stripping vessel. The perforated section may comprise a grate. Baffles may also include an imperforate section which is vertically aligned with a downcomer section of a superjacent baffle.

摘要： A fluid feed distributor improves particle and feed contacting by using a flow actuated plug to prevent back flow of fluidizable particles through a fluid feed outlet when fluid feed to a riser conduit ceases. The plug is located at or near the bottom of a riser contacting conduit where a back flow of particles can occur. The plug drops into the fluid feed outlet when fluid flow stops. The plug and a supporting stem will usually have an at least partially vertical orientation to provide the preferred gravity closure of the flow actuated plug. The plug arrangement can also provide improved feed distribution. Preferably the fluid actuated plug will act in conjunction with a fluid dispersion device. The dispersion device may be located upstream in a feed conduit that houses the plug and a fluid outlet at its downstream end. In addition, the fluid actuated plug can also serve to adjust the dispersion of feed fluid during operation of the unit. The restricted opening that receives the plug may comprise a spray nozzle that further improves feed dispersion. A restricted opening in the form of a venturi offers particularly advantageous feed distribution benefits when cooperatively arranged with the plug.

摘要： The invention improves a system and apparatus for the recovery of fine solid particles entering the slurry system of a fluidized catalytic contacting process by returning a portion of the recovered solids from the main separator directly back to the reactor stripper. The invention recovers fine particulate material from an FCC main column and returns the particulate material to an FCC stripper to reduce the amount of fine material that continues to recycle through the FCC reactor and product separator. By returning fine particulate material from the FCC product separation zone directly to a low velocity area of the stripping section, the invention breaks the reactor--main column recycle loop that concentrates the fines. Fines entering the reactor stripper will not be carried back into the cyclones for unwanted return to the main column. By the recycling of fines to the stripper via this invention, the fines concentration in the slurry system can decrease by up to 300%.
摘要翻译： 本发明通过将一部分回收的固体从主分离器返回到反应器汽提器来改进用于回收进入流化催化剂接触方法的浆料体系的细固体颗粒的系统和装置。 本发明从FCC主色谱柱回收细颗粒物质，并将颗粒物质返回到FCC汽提器中，以减少继续通过FCC反应器和产物分离器再循环的细料的量。 通过将FCC产物分离区的细颗粒物质直接返回到汽提段的低速区域，本发明打破了浓缩细粒的反应器 - 主塔循环回路。 进入反应器汽提器的细粉不会被带回到旋风分离器中，以便不必要地返回到主色谱柱。 通过本发明将细粒再循环到汽提塔中，浆料系统中的细粉浓度可以降低高达300％。

摘要： An FCC feed injection arrangement injects feed transversely from the sides of a restricted opening into a stream of FCC catalyst to provide good feed and catalyst contacting in an arrangement that simplifies external pipe configurations and maintenance of the feed injection system. The invention forms a venturi or restricted opening by forming a generally square opening between two parallel extended chords on opposite sides of the riser. A venturi area may be built out of refractory lining or other abrasion resistant structures. The invention may use horizontally extended pipes that are tangentially positioned apart from each other across from the restricted opening to provide a simple construction for the feed injection arrangement. The pipes are easily inserted and withdrawn from the riser to permit easy maintenance of the nozzles in the highly erosive environment. Insertable pipe distributors for distributing feed may be arranged to provide good overall distribution while also providing cooling to the outer surface of the distribution conduit to prevent coking. The distribution conduit may also be arranged to provide mixing of oil and steam near the injection point of the nozzles.

摘要： A uniflow cyclone that has multiple inlets, normally achieved via a vane, a barrel length, then a solids collection channel of larger diameter but concentric with the barrel and a tangential solids outlet to either a plenum or a dust hopper. The gas flows past the enlarged channel and continues through additional barrel length to an outlet zone. The cyclone would normally have a concentric center pipe the extends from the vane to the gas outlet of the cyclone.

摘要： A process for improving flow properties of crude may include processing a first crude stream, which may in turn include cracking the first crude stream with fresh catalyst to form a cracked stream and spent catalyst, and then mixed with an unprocessed second stream. The spent catalyst may be regenerated to form fresh catalyst, which may then be recycled. At least part of the cracked stream may be mixed with a second crude stream. A ratio of the second crude stream to the first crude stream may be between about 0.5:1 and about 9:1. A ratio of part of the cracked stream to add to the second crude stream may be selected to achieve a API gravity of at least about 18. The first crude stream may be heated and stripped before being cracked.

摘要： Cyclone separators and separator devices for separating gas and entrained particles from a particle-contaminated gas stream are provided. The cyclone separator comprises a cyclone body having a first end and a second end with a sidewall extending therebetween. The cyclone body defines a cyclone gas inlet for receiving the particle-contaminated gas stream. A cyclone gas outlet is for discharging the clean gas stream. A centripetal accelerator is proximate the cyclone gas inlet to induce centripetal acceleration of the particle-contaminated gas stream. The sidewall defines a discharge opening between the first end and the second end for discharging separated particles from the cyclone body. The discharge opening has a leading edge and a top edge in relation to a flow path of entrained particles within the particle-contaminated gas stream. The top edge extends at an acute angle relative to the leading edge.
