Abstract: The invention concerns a method for converting heavy hydrocarbon feedstocks of which at least 50% by weight boils at a temperature of at least 300° C., and in particular vacuum residues. The feedstocks are subjected to a first step a) of deep hydroconversion, optionally followed by a step b) of separating a light fraction, and a heavy residual fraction is obtained from step b) of which at least 80% by weight has a boiling temperature of at least 250° C. Said fraction from step b) or the effluent from step a) is then subjected to a second step c) of deep hydroconversion. The overall hourly space velocity for steps a) to c) is less than 0.1 h−1. The effluent from step c) is fractionated to separate a light fraction. The heavy fraction obtained, of which 80% by weight boils at a temperature of at least 300° C., is sent to a deasphalting step e). The deasphalted fraction DAO is then preferably converted in a step f) chosen from ebullated bed hydroconversion, fluidised bed catalytic cracking and fixed bed hydrocracking.

Abstract: The invention is a method for deacidizing a gaseous effluent comprising acid compounds, such as CO2 and/or H2S, and a device for implementing the method, through contact with a demixing absorbent solution. Regeneration is performed by vapor injection into the liquid guard (202) formed by the regenerated absorbent solution in the bottom of regeneration column (G). The vapor is generated within a reboiler (203) from a fraction of the regenerated absorbent solution withdrawn from the regeneration column. Vapor injection enables convective movement of the liquid for preventing any decantation phenomenon in the bottom of the regeneration column bottom which is harmful to the smooth operation of the deacidizing process.

Abstract: Process for hydrotreatment of hydrocarbon-containing feedstock comprising sulphur- and nitrogen-containing compounds, comprising: a) separating the feedstock into heavy and light fractions, b) a first hydrotreatment stage wherein the heavy fraction and hydrogen are contacted with a first hydrotreatment catalyst Z1 to produce a first desulphurized effluent, c) separating the first effluent into a first gaseous fraction and a first liquid fraction, d) purifying the first gaseous fraction to produce a hydrogen-rich flow, e) mixing the light fraction with the first liquid fraction to produce a mixture, f) a second hydrotreatment stage wherein the mixture from stage e) and the hydrogen-rich flow from stage d) are contacted with a second hydrotreatment catalyst Z2 to produce a second desulphurized effluent, g) separating the second effluent into a second gaseous fraction and a second liquid fraction, h) recycling at least part of the second gaseous fraction to b) as a flow of hydrogen.
