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.
