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-), 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-), and cooling the reaction effluent from the hydrotreatment or hydroconversion reaction section (R-). The present invention also relates to a use of a coil-wound heat exchanger (S-) in a process for hydroconversion or hydrotreatment of a hydrocarbon feedstock.

Coil-wound heat exchanger for hydrotreatment or hydroconversion

The present invention relates to a device and a process for hydroconversion or hydrotreatment of a hydrocarbon feedstock, comprising in particular a single coil-wound heat exchanger (S-), 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: preheating a hydrocarbon feedstock/hydrogen stream mixture to a reactor inlet furnace (F-) of a hydrotreatment or hydroconversion reaction section (R-), and cooling the reaction effluent from the hydrotreatment or hydroconversion reaction section (R-). The present invention also relates to a use of a coil-wound heat exchanger (S-) in a process for hydroconversion or hydrotreatment of a hydrocarbon feedstock.

An installation for the hydrotreatment and hydroconversion of hydrocarbon-containing feedstocks, with a common fractionation section, for the production of at least one of the following products: naphtha (light and/or heavy), diesel, kerosene, distillate and residue: An integrated hydroconversion and hydrotreatment process implementing said installation.
