Abstract: The present invention relates to a method for treating a pyrolysis gasoline C5+ containing monoolefinic, diolefinic and sulfur hydrocarbons, comprising at least, and in any order: a) a step of hydrotreating the pyrolysis gasoline or a hydrocarbon fraction C6+ originating from the pyrolysis gasoline, in the presence of hydrogen and at least one hydrotreatment catalyst at a temperature ranging between 220 and 380° C. so as to produce a hydrotreated effluent; b) a step of separating the pyrolysis gasoline or the hydrotreated effluent originating from step a) when said step is completed before step b), into a separation column for separating into a top hydrocarbon fraction C5− and a bottom hydrocarbon fraction C6+, said separation column comprising a reboiling section including two heat exchangers, at least one of the two exchangers being configured to perform a heat exchange with a portion of the bottom fraction that is recycled in the column via the reboiling section. According to the invention, one of the two heat exchangers of the reboiling section is supplied with at least one portion of the hydrotreated effluent so as to supply part of the heat required to operate the reboiling section.

Abstract: The invention relates to a method and a plant for removing the acid compounds contained in two gaseous effluents of different origins, comprising using a single amine-based absorbent solution circulating between a first absorber and a regenerator, and a second absorber and the same regenerator. The present invention advantageously applies for example to CO2 capture within a single plant intended for capture of the gaseous effluents produced upon hydrogen production through steam reforming of a gaseous hydrocarbon feed, such as combustion fumes and syngas.

Abstract: Process for producing a light gasoline having a sulfur content of less than 10 ppm by weight, with respect to the total weight of the light gasoline, starting from a gasoline containing sulfur compounds, olefins and diolefins, which process includes a) a stage of selective hydrogenation to hydrogenate the diolefins and a reaction for increasing the molecular weight of a part of the sulfur compounds; b) a stage separating the effluent obtained from stage a) into a gaseous fraction, a light gasoline cut and a heavy gasoline cut, stage b) being carried out in a fractionation column containing n plates, n being an integer of 20 or more, the first plate being the reboiler and the plate “n” being the condenser, wherein the light gasoline cut is withdrawn from the fractionation column at the plate “n-i”, with i being 1 to 10.

Abstract: The present invention concerns a process for the desulphurization of a gasoline cut containing sulphur-containing compounds, olefins and diolefins, comprising at least the following steps: a) fractionating the gasoline in order to recover a light gasoline cut LCN and a first heavy gasoline cut HCN; b) carrying out a first step for desulphurization of the first heavy gasoline cut HCN; c) partially condensing the first desulphurization effluent obtained from step b) in a manner such as to produce a gaseous phase essentially constituted by hydrogen and H2S and a liquid hydrocarbon phase HCN comprising dissolved H2S; d) separating the liquid hydrocarbon phase HCN into an intermediate gasoline cut MCN and a second heavy gasoline cut HHCN; e) carrying out a second step for desulphurization of the second heavy gasoline cut

Abstract: A process for treating a gasoline containing sulfur compounds, olefins and diolefins comprises step a) bringing into contact the gasoline, hydrogen and a hydrodesulfurization catalyst, in at least one reactor. In step b) effluent from a), hydrogen, and a hydrodesulfurization catalyst are brought into contact in at least one reactor. In step c) effluent from b) is sent to a separation drum operating at a pressure of between 1.0 and 2.0 MPa to obtain a gaseous fraction containing H2S and hydrogen and a liquid fraction containing desulfurized gasoline and a fraction of dissolved H2S. In step d), the liquid fraction is sent to a stabilization column to obtain at the top a stream comprising residual H2S and C4- hydrocarbon compounds and at the bottom a stabilized gasoline. In step e), the gaseous fraction is recycled at least in part to at least one of steps a) and/or b).
