Patent ID: 7238275

Claim:
A system for integrated hydrotreating of a first and a second feedstock with different boiling point ranges, comprising: an interbed separator that is configured to produce a separator liquid and to receive a first hydrocarbonaceous feed and a second hydrocarbonaceous feed, wherein the first feed has a temperature that is effective to preheat and vaporize at least part of the second feed, thereby producing a preheated and at least partially vaporized second feed; wherein the first hydrocarbonaceous feed has a higher boiling point range than the second hydrocarbonaceous feed; a first hydrotreating reactor configured to provide the portion of the first feed, and a second hydrotreating reactor configured to receive at least a portion of the preheated and at least partially vaporized second feed and to produce a liquid product; and wherein the plant is further configured such that the liquid product and the separator liquid are separately withdrawn from the system.
