Abstract: The present invention relates to a process for fluid catalytic cracking of a feedstock comprising a light tight oil and at least one conventional feedstock in order to produce an effluent, in which the feedstock has a content of light tight oil so that the density of the feedstock is between 0.84 and 0.91.

Abstract: The present invention describes a process for heating the reboiler of the propane/propylene separation column situated downstream of an FCC unit and fed with the C3 cut from said FCC unit, a process consisting of heating the water in a hot water circuit by means of one or more process fluids originating from units placed upstream and/or downstream of the FCC unit and called hot fluids, one of these fluids being constituted by the overhead vapours from the fractionation column connected to the mild hydrocracking unit.

Abstract: A process for desulfurizing a cracked naphtha containing organic sulfur compounds: a) feeding the cracked naphtha to a distillation column comprising a bottom reboiler; b) fractionating said cracked naphtha into a light naphtha fraction and a heavy naphtha fraction which is removed as bottoms from the distillation column; c) feeding the heavy naphtha fraction and hydrogen to a hydrodesulfurization unit containing a hydrodesulfurization catalyst to produce a desulfurized heavy naphtha effluent. The process further includes providing heat to the distillation column by an intermediate reboiler powered with a heat source having a temperature lower than that one of the bottom reboiler.

Abstract: The invention relates to a method and to a device for chemical looping combustion CLC of a solid hydrocarbon feed wherein it is proposed to inject the solid hydrocarbon feed so as to limit any occurrence of sticking of the feed to the walls of the injection device. The solid feed is fed into a conveying zone operating under fluidized bed conditions and opening into a combustion reactor. A fluidization gas is injected into this conveying zone while controlling the flow of gas in such a way that the superficial velocity of the gas in the conveying zone is higher than the terminal velocity of the solid hydrocarbon feed particles and the terminal velocity of solid particles present in the combustion reactor, and while controlling the fluidization gas temperature in such a way that the temperature in the conveying zone is less than or equal to 500° C.
