Patent number: 9089839Abstract: A combustion device for meeting the energy demand of processes for producing light olefins (ethylene and propene) in fluidized-bed catalytic cracking units. The combustion device is used to burn heating oil and to keep burning the coke deposited on the catalyst, with a view to heating it to meet the energy demand of the reaction, combustion taking place smoothly and uniformly, preventing the formation of hotspots within the catalytic bed and in the dilute phase following combustion (afterburning), thereby minimizing deactivation of the catalyst and the risk of damage to the equipment inside of the combustion device.Type: GrantFiled: September 14, 2010Date of Patent: July 28, 2015Assignee: PETROLEO BRASILEIRO S.A.-PETROBRASInventors: Jose Mozart Fusco, Emanuel Freire Sandes, Naiara dos Santos Lages, Geovani Aliatti, Jose Geraldo Furtado Ramos, Ricardo Serfaty, Nelson Patricio Junior

Patent number: 7967975Abstract: 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.Type: GrantFiled: October 28, 2009Date of Patent: June 28, 2011Assignee: Petróleo Brasileiro S.A. - PetrobrasInventors: José Geraldo Furtado Ramos, Eduardo Cardoso de Melo Guerra, José Mozart Fusco, Aurélio Medina Dubois, Wilson Kenzo Huziwara, Waldir Pedro Martignoni

Patent number: 7867321Abstract: 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 the 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.Type: GrantFiled: December 13, 2007Date of Patent: January 11, 2011Assignee: Petroleo Brasileiro S.A. - PetrobrasInventors: Emanuel Freire Sandes, Paulo Sérgio Freire, José Geraldo Furtado Ramos, Aurélio Medina Dubois, José Mozart Fusco, Eduardo Cardoso de Melo Guerra, Wilson Kenzo Huziwara

Patent number: 7799285Abstract: A stripping apparatus is described for the gas-solid separation process in a fluidized bed in a counter-current flow of a stripping fluid. The apparatus includes sets of perforated baffle-plates with holes, fixed in series, alternating central and lateral plates inside a stripping chamber. The holes in the baffle-plates, in number, size and in circular or elliptical lay-out, are oriented in offset position in relation to the holes in the parallel and subsequent baffle-plates, reducing the damage of erosion on the perforated baffle-plates and optimizing stripping of the fluidized solid particles.Type: GrantFiled: April 10, 2007Date of Patent: September 21, 2010Assignee: Petróleo Brasileiro S.A.-PetrobrasInventors: Wilson Kenzo Huziwara, Claudio Maria de Lacerda Alvarenga Baptista, Henrique Soares Cerqueira, José Mozart Fusco

Patent number: 7276210Abstract: A stripping apparatus for desorbing gases from solid particles through which flows counter-currently a stripping fluid is described, which comprises a series of sets of at least two parallel, segmented, baffle plates each, with the segmented baffles being oriented so that the rows are offset relative to rows of other levels, where the thickness and separation of said sets of baffles is so dimensioned as to reduce coalescence of the size of the formed bubbles and optimize the hydrocarbons desorption from said fluidized solid particles. The solid particles are mainly spent catalyst particles from a FCC process. The stripping process to be carried out in a fluidized bed comprises contacting the spent catalyst with a stripping fluid that flows upwardly in the fluidized bed in the form of bubbles. Adsorbed hydrocarbons present in the spent catalyst are transferred from the catalyst emulsion that flows downwardly to the upwardly moving bubbles, so as to promote the efficient recovery of cracked products.Type: GrantFiled: August 20, 2003Date of Patent: October 2, 2007Assignee: Petroleo Brasileiro S.A. -PetrobrasInventors: Henrique Soares Cerqueira, Cláudia M De Lacerda Alvarenga Baptista, José Mózart Fusco

Patent number: 7081229Abstract: 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).Type: GrantFiled: April 15, 2003Date of Patent: July 25, 2006Assignee: Petroleo Brasileiro S.A.Inventors: Wilson Kenzo Huziwara, Eduardo C. de Melo Guerra, Waldir Pedro Martignoni, Aurélio Medina Dubois, Luiz Carlos Casavechia, José Mozart Fusco

Patent number: 6197266Abstract: A cyclone leg sealing system is composed of one or more intermediate solids-accumulation chambers delimited by two sealing valves and in series, the function of the valves being to prevent the back-flow of particulate material towards the inside of the separating cyclones in fluid catalytic cracking (FCC) processes, thereby ensuring the maximum efficiency of the separating effected by the cyclone.Type: GrantFiled: October 28, 1998Date of Patent: March 6, 2001Assignee: Petroleo Brasileiro S.

Patent number: 6059958Abstract: 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.Type: GrantFiled: September 18, 1997Date of Patent: May 9, 2000Assignee: Petroleo Brasileiro S.A.-PetrobrasInventors: Jose Geraldo Furtado Ramos, Jose Mozart Fusco, Moacir Jose Bampi, Emanuel Freire Sandes, Francisco Carlos Da Costa Barros, Jorivaldo Medeiros, Claudio Fonseca Machado Dos Santos, Aurelio Medina Dubois, Ingrid Alexandra Zech, Monica Einsfeldt, Maria Celia Dos Santos Da Rocha
