Abstract:
1. An integrated hydrocracking process for producing cracked hydrocarbons from a feedstock including: a. separating the hydrocarbon feed into an aromatic-lean fraction and an aromatic-rich fraction; b. hydroprocessing the aromatic-rich fraction in a first vessel of a first stage hydroprocessing reaction zone to produce a first vessel first stage hydroprocessing reaction zone effluent; c. hydroprocessing the aromatic-lean fraction in a second vessel of the first stage hydroprocessing reaction zone to produce a second vessel first stage hydroprocessing reaction zone effluent; d. fractionating a mixture of first vessel first stage hydroprocessing reaction zone effluent and second vessel first stage hydroprocessing reaction zone effluent to produce one or more fractionating zone product streams and one or more fractionating zone bottoms streams; e. hydroprocessing at least a portion of the fractionating zone bottoms stream in a second stage hydroprocessing reaction zone to produce a second stage hydroprocessing reaction zone effluent; and f. conveying the second stage hydroprocessing reaction zone effluent to the step of fractionating.
