    Abstract: The focus of this invention is the economic integration of two well-known technologies to provide an economical, integrated process unit for the complete conversion of residue feedstock. The technologies employed are heavy oil hydrocracking, which can be via an ebullated-bed, fixed-bed or slurry bed process, and coking, which can be via a delayed coking or fluid coking (with or without integrated gasification). The invention is most applicable to residue hydrocracking of high CCR and metals atmospheric and vacuum residues where coking of the unconverted hydrocracker residue is the most practical and economical method of hydrocracking bottoms disposal.

    Abstract: The present invention relates to the extraction of gasoline from a gas G, with
    (a) a step of extracting gasoline from the gas to be treated comprising methanol GM obtained from step (d),
    (b) a step of separating said fluid GL1 partially condensed in step (a), producing a first aqueous liquid phase A1, a first liquid phase H1 of hydrocarbon(s) a gaseous phase G1 obtained from the gas G; (c) a step of contacting a portion of the gas G to be treated with said first aqueous liquid phase A1, producing a second aqueous liquid phase A2, a gaseous phase of gas to be treated comprising methanol GM′; (d) a step of mixing said gaseous phase of gas to be treated comprising methanol GM′ with the remainder of the gas G to be treated, producing a gas to be treated comprising methanol GM,
    (e) a step of stabilizing said first liquid phase H1 of hydrocarbon(s).

    Abstract: A process for hydrocracking a petroleum feedstock involves: (a) hydrocracking the feedstock to obtain a hydrocracked effluent; (b) liquid/gas separation of the effluent to obtain a gaseous effluent and a liquid effluent; (c) fractionating the liquid effluent at a pressure P1, producing a first distillate and a first residue, (d) recycling a first portion of the first residue to hydrocracking, (e) rectifying a second portion of the first residue at a pressure P2 lower than or equal to the pressure P1, to obtain a secondary distillate, a secondary residue and a vapor stream, (f) purging a portion of the secondary residue, and (g) recycling all or part of the secondary distillate to hydrocracking.

    Abstract: The present invention describes a process for obtaining para-xylene from a feedstock containing xylenes, ethylbenzene and C9+ hydrocarbons, said process comprising a single stage A of separation in a simulated moving bed carried out with a zeolite as adsorbent and a desorbent and making it possible to obtain at least three fractions, a fraction A1 comprising a mixture of para-xylene and of desorbent and two fractions A21, A22 comprising ethylbenzene (EB), ortho-xylene (OX) and meta-xylene (MX) and desorbent, said stage is carried out at a temperature between 20° C. and 250° C., under a pressure between the bubble pressure of the xylenes at the operating temperature and 2.0 MPa, and with a ratio by volume of the desorbent to the feedstock in the unit for separation 2 in a simulated moving bed is between 0.4 and 2.5, a stage B of fractionation by distillation in a 2-cut distillation column of the fractions A21 and A22 resulting from stage A, in which said fractions are introduced separately at distinct injection points, and makes it possible to obtain a fraction B2 containing ethylbenzene, ortho-xylene and meta-xylene, and a fraction B42 devoid of aromatic compounds having 8 carbon atoms and containing desorbent.

    Abstract: The present invention relates to a device and a process for hydroconversion or hydrotreatment of a hydrocarbon feedstock, comprising in particular at least one coil-wound heat exchanger (S-1), said coil-wound exchanger being a single-pass heat exchanger formed by a vertical chamber in which one or more bundles of tubes are helically wound around a central core, as numerous superposed layers, for: heating and directly distributing a hydrocarbon feedstock/hydrogen stream mixture to a hydrotreatment or hydroconversion reaction section (R-1), and cooling the reaction effluent from the hydrotreatment or hydroconversion reaction section (R-1). The present invention also relates to a use of a coil-wound heat exchanger (S-1) in a process for hydroconversion or hydrotreatment of a hydrocarbon feedstock.
