Patent number: 7544333Abstract: A device for the fluidized bed cracking of a hydrocarbon charge using two reaction chambers linked together by a cooling particles transferrer, a fractionating column and conduits to supply the hydrocarbonated effluents from each of the two chambers to the fractionating column. The fractionating column has, internally, at least two different areas: a first partitioned fractionating area in the form of two compartments, each of which communicates with a second common fractionating area. The conduits for the supply of effluents from the first and the second reaction chamber terminate, respectively, in the first and second compartment of the partitioned fractionating area. A recycler and an injector are provided for recycling and injecting into one of the reaction chambers of at least one cut drawn off from the partitioned fractionating compartment of the effluents of the other reaction chamber.Type: GrantFiled: May 18, 2004Date of Patent: June 9, 2009Assignee: Total Raffinage Distribution S.A.Inventors: Marcellin Espeillac, Pierre Crespin

Patent number: 6869576Abstract: A process for hydrotreating a hydrocarbon feedstock (1) involving the use of at least one hydrotreatment, particularly hydrodesulfurization, reactor (2) and a fractionation unit (3), which latter contains two distinct injection zones (4, 5) for the hydrocarbon feedstocks, a common zone (8) of vaporization of the light fractions and two distinct draw-off lines (6, 7) for the liquid bottoms; the hydrocarbon feedstock (1) being subjected to a preliminary treatment either in a first hydrodesulfurization reactor (20) the operating conditions of which (P, T, LHSV) may be different from those of the hydrotreatment reactor (2), or in a sweetening apparatus or else in a sulfur trap, the hydrocarbon feedstock being then injected into the first injection zone (4) of the fractionation unit (3), the liquid bottoms being removed through the draw-off line (6) of the injection zone (4) and passed into a hydrotreatment reactor (2), the effluents from said reactor (2) being injected into a second injection zone (5) of the fracType: GrantFiled: December 29, 2000Date of Patent: March 22, 2005Assignee: Total Raffinage Distribution S.A.Inventors: Marcellin Espeillac, Pierre Crespin

Patent number: 6805171Abstract: A method wherein the particles are homogeneously distributed like rain to constitute a horizontal bed of particles on the entire section of the chamber (1). The invention is characterised in that it consists in temporarily modifying at least once the loading conditions, so that the profile of the surface (8) of the bed of particles forms, at least at the periphery thereof, an angle &agr; with the horizontal ranging between 6° and 25°, preferably, between 10° and 20°, and in subsequently restoring the loading conditions to obtain a horizontal bed.Type: GrantFiled: December 29, 2003Date of Patent: October 19, 2004Assignee: Total Fina Elf FranceInventors: Pierre Crespin, Daniel Barthod, Emmanuelle Petitjean, Marc Lebouteiller

The effluents from each of the reaction chambers (1; 16) are fractionated in part separately in one and the same partially partitioned fractionating unit, and at least one cut (12) obtained by separately fractionating the effluents from one of the two reaction chambers (1; 16) is, as a whole or in part, reinjected into the other chamber.Type: GrantFiled: July 3, 2001Date of Patent: July 27, 2004Assignee: Total Raffinage Distribution S.A.Inventors: Marcellin Espeillac, Pierre Crespin

Patent number: 4610695Abstract: A fluid fuel mixture is formed of a suspension of a pulverized solid fuel and of at least one aqueous phase representing from 15 to 40 percent of the mixture before an optional incorporation of an additive. The mixture can comprise, as a supplement to particle-size fractions of the pulverized solid fuel, or as a replacement for some of these fractions, additional particle-size fractions produced from heavy petroleum residues of a natural or synthetic origin which are solid at the temperature at which the invention is practiced. The fluid fuel mixture may be used, for example, in boilers, industrial furnaces, or gasification reactors.Type: GrantFiled: March 3, 1986Date of Patent: September 9, 1986Assignee: Compagnie Francaise de RaffinageInventors: Pierre Crespin, Francois Guay, Paul H.
