    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 second stage cyclone dipleg termination device for cyclones that operate under conditions in which the pressure in the top of the cyclone dipleg is lower than the external pressure where fine particulate matter is collected and discharged. The second stage cyclone dipleg termination device operates in a separator vessel (2) or a vessel of the regenerator of a fluid catalytic cracking (FCC) converter to reverse the pressure conditions commonly found in this type of equipment. One end of a cyclone dipleg (7) is joined to a collector vessel (11), in such a way that a portion of the dipleg (7) enters into the inside of the collector vessel (11). The end of the dipleg (7) is connected to the conventional, normally used sealing device (17) in second stage cyclone (4) diplegs (7). The collector vessel (11), in turn, has on its bottom an outlet in the form of the dipleg (14). On the inside of this outlet an injector device is introduced (16) through which a fluid under high pressure is discharged, associated with a “venturi” type nozzle (15), which moves or drags the particulate matter discharged by the dipleg (7) of the cyclone (4) through the sealing valves (17), inside the collector vessel (11) the exterior of the collector vessel (11).
