摘要： A system for sealing the legs of two stages of cyclones in series used in fluid catalytic cracking (FCC) processes, comprising a terminal leg configuration, which is devoid of moving parts and makes use of a long-radius curve, and which changes the flow direction of the descending mass flow of catalyst in dense phase into a plane orthogonal to the ascending gaseous flow. This prevents the entry of gaseous phase inside the leg, and promotes efficient sealing and preventing the “packing-down” of the dense bed of particulates.

摘要： An improved cyclone system for disengaging solid and gaseous particles in fluid catalytic cracking (FCC) processes with reduced coke formation in disengager vessels, without favoring release of the disengaged catalyst into cyclones in subsequent stages, said system comprising legless cyclones 42 fitted with external collector pipes 43, is described.The collector pipes 43 optimize the purge of gases coming from the disengager vessel 49, reducing the time the hydrocarbons remain inside said disengager vessel 49, thus preventing overcracking and subsequent coke formation. Positioning of the external collector pipes 43 prevents release of the disengaged catalyst into cyclones in subsequent stages.The present invention also relates to a process and device for disengaging solid and gaseous particles in fluid catalytic cracking (FCC) processes, reducing coke formation in disengager vessels and minimizing the release of catalyst into consecutive stages, said process and device being part of the system of the present invention.

摘要： A process for the fluid catalytic cracking of heavy feeds under a heat balance regime is described, where one or more catalyst coolers external to the regenerator cool a stream of regenerated catalyst. A portion of said stream returns to the regenerator and a portion of the cooled regenerated catalyst is admixed to the non-cooled regenerated catalyst at a temperature substantially lower than the regenerator temperature, said admixture being brought into contact with the hydrocarbon feed to be cracked. As a result, the control of the catalyst circulation is rendered independent from the heat balance of the unit, with minimization of the thermal cracking, and therefore lower coke and fuel gas products.

摘要： A device and a method for operating it for application in a vertical tube reactor with downward flow (downer), has the aim of ensuring the intimate mixing of the solid particulate catalyst with a reagent fluid. Homogeneous distribution of catalyst is due to the use of a plate having perforations. Said perforated plate normally allows the passage of a portion of the stream of catalyst. The other portion overflows the edge of the plate, flowing in the form of an annular curtain, near the inner surface of the surrounding tube of the device. After passing beyond the perforated plate, the curtain-flow undergoes a deflection produced by an annular screen, to be mixed with the stream originating from the orifices in the perforated plate. A hydrocarbon charge is injected below the perforated plate, forming a certain angle with respect to the direction of the downward flow of catalyst, by means of inlets distributed uniformly about cross sections of the surrounding tube. After the mixing region, the diameter of the device, when smaller than the diameter of the associated tube reactor, expands slightly.

摘要： The present invention relates to a system for the separation of suspensions of spent catalysts and hydrocarbons formed in an FCC unit with multiple ascending flow reaction tubes, comprising interconnections between each of the ascending flow reaction tubes and the separator vessel, each interconnection also comprises two sections. The outside sections of the separator vessel are inclined and are connected to a single vertical section, which penetrates into the interior of the separator vessel, and which has at its lower end an open device for draining the spent catalyst from the suspensions separated in this sector. In the same vertical section, at the end of its internal part at the separator vessel, a series of two sets of cyclones are installed, the first set containing cyclones without sealing legs, and the second set containing conventional cyclones of the first stage. The present invention also relates to a process for the separation of suspensions of spent catalysts and hydrocarbons using the said separation system.
