摘要： A distributor (9) for the equalization of flow rate of cyclones in closed cyclone systems installed in the interconnection of the cyclones of the disengager vessel of the gas-solid suspension of the fluid catalytic cracking (FCC) processes is described, that distributes the gases exiting the first stage cyclones so as to promote a desirable and uniform flow rate of said gases through said space, besides absorbing the relative movements between the cyclones caused by the differential thermal expansion. The distributor of the invention secures a homogeneous accommodation of the gas-solid suspension in a connecting pipe, allowing a uniform cyclone operation in the next stage, no matter the geometry of the riser-cyclone set or of the downer-cyclone set.

摘要： Emission of nitrogen oxides from a mineral-burning process, for example a cement-manufacturing process, is reduced by passing the exhaust gas from the rotary kiln in which the mineral raw materials are burnt to a combustion zone in which solid fuel elements, for example waste tyres, are maintained for a sufficient period and at a sufficient temperature for at least 30% by weight of the volatile combustible content of the solid fuel elements to be combusted, the combustion zone comprising at least one region in which the combustion of the solid fuel elements occurs under sub-stoichiometric conditions. The solid fuel elements may be introduced into the hot gas stream at at least one point between the mineral-inlet end of the rotary kiln and the lowermost cyclone of an associated preheater system, e.g. into the gas stream within a precalciner vessel or riser duct. Preferably, tertiary air from a clinker cooling apparatus is supplied downstream of the combustion zone (relative to the flow of kiln exhaust gas). As an alternative, the solid fuel elements may be introduced into a Lepol grate preheater.

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： A CFB furnace or reactor unit is provided having enhanced circulation of the reagents finest particles. The improved circulation is achieved by recycling gas having entrained fine particles from a solids collection hopper connected to the solids separator back into the reactor. A system of one or more conduits connects the upper portion of the solids collection hopper with the reactor. The conduit system is equipped with means for recycling gas from the hopper to the reactor. The invention is an inexpensive system which permits recycling of the finest particles that would otherwise be carried over with the gas flow exiting the separator.

摘要： An improved stripper section design is provided for use in fluid catalytic cracking (FCC) units. The stripper section contains means for imparting rotational movement to the FCC cracking catalyst as it traverses the stripping section. In one embodiment the stripper section contains at least one rotation vane that is preferably disposed on the surface of a stripper section tray. The rotation vane provides angular, rotational movement to the cracking catalyst as it traverses the stripper section. Vertical movement is imparted to the cracking catalyst due to gravity and radial movement is imparted to the catalyst due to the slanted nature of the tray. Through the use of the rotation vanes the contact between the catalyst particles and the stripping steam is increased, thereby improving the overall efficiency of the FCC operation.

摘要： An FCC apparatus places a quench chamber above a reactor vessel and a hot stripper below a reactor vessel to provide a progressively decreasing temperature profile up the structure of the FCC arrangement and equipment for sequential reaction control. A riser contains the primary catalytic reactions of the hydrocarbon vapor and delivers the reacted vapors to the reactor structure. Starting from the bottom of the structure the hot stripper has the highest temperature and desorbs or displaces hydrocarbons from the catalyst to terminate long residence time catalytic reactions. Above the hot stripper bulk separation equipment divides the main vapor and catalyst stream to limit residence time of major catalytic reactions. At a yet higher elevation and lower internal temperature quench equipment arrests thermal reactions of the vapor stream. This structure arrangement permits reliable control of reaction time to obtain desired products and enhances mechanical reliability of the structure.

摘要： A horizontal cyclone separator in which a furnace section and a vortex chamber communicating with the furnace section and having an inlet which extends a fraction of the length of the furnace section receives a mixture of the gaseous products of combustion and solids entrained by the gases. A coaxially disposed tube extends partially into the chamber to allow the separated gases to exit the separator. A ring-shaped solids deflector is disposed on the vertical wall opposite the coaxially disposed tube to prevent solids from bouncing off the rear wall towards the center of the separator and into the path of the separated gas stream. The separated solids fall into an outlet trough formed in a lower portion of the furnace section for returning the solids to the furnace section.
