Abstract
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.
