- COIL-WOUND HEAT EXCHANGER FOR HYDROTREATMENT OR HYDROCONVERSION

摘要

The first object of the present disclosure is to improve hydroconversion or hydrotreatment devices and methods, especially in terms of energy efficiency and operating costs. More specifically, the present invention relates to a device and a method for hydroconversion or hydrotreatment of a hydrocarbon feedstock, including, in particular, at least one coil-wound heat exchanger (S-1). The coil-wound exchanger is 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, suitable for: heating a pre-heat hydrocarbon feedstock/hydrogen stream mixture; distributing the 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 the coil-wound heat exchanger (S-1) in the method for hydroconversion or hydrotreatment of the hydrocarbon feedstock.
