PROCESS FOR THE CONVERSION OF A HYDROCARBONACEOUS FEEDSTOCK

A hydrocarbonaceous feedstock is converted in a process comprising the following steps: (a) the feedstock is contacted with hydrogen under hydrotreating conditions to yield hydrotreated product; (b) the hydrotreated product is subjected to a separation treatment to separate at least hydrogen from th...

Zusammenfassung:	A hydrocarbonaceous feedstock is converted in a process comprising the following steps: (a) the feedstock is contacted with hydrogen under hydrotreating conditions to yield hydrotreated product; (b) the hydrotreated product is subjected to a separation treatment to separate at least hydrogen from the hydrotreated product to obtain a liquid hydrotreated product stream; (c) at least a portion of the liquid hydrotreated product stream is subjected to a stripping treatment to separate a light product from the liquid hydrotreated product stream, leaving a heavy hydrotreated product; (d) the heavy hydrotreated product is separated under reduced pressure into a least one gaseous stripped fraction and at least one liquid stripped fraction in a separation zone, wherein at least a portion of a liquid stripped fraction is reheated and recycled to the separation zone, in which process at least a portion of the liquid stripped fraction is reheated by heat exchange between at least a portion of the liquid hydrotreated product stream and/or at least a portion of the heavy hydrotreated product.
