Patent ID: 8540949

Claim:
An apparatus for hydroprocessing hydrocarbons comprising: a hydrocracking reactor in communication with a first hydrogen line and a first hydrocarbon feed line for hydrocracking a hydrocarbon feed stream to lower boiling hydrocarbons transported in a hydrocracking effluent line; a cold separator in communication with the hydrocracking reactor for providing a vaporous hydrocracking effluent stream comprising hydrogen in an overhead line and a liquid hydrocracking effluent stream in a bottoms line; a hydrotreating reactor in communication with a second hydrogen line for hydrotreating a second hydrocarbon feed stream to produce a hydrotreating effluent stream; a warm separator in communication with the hydrotreating reactor for separating the hydrotreating effluent stream into a vaporous hydrotreating effluent stream comprising hydrogen in a warm overhead line and a liquid hydrotreating effluent stream in a warm bottoms line, wherein the bottoms line of the cold separator is joined with the warm overhead line of the warm separator; and a fractionation section in downstream communication with the hydrocracking reactor for fractionating the hydrocracking effluent stream and the hydrotreating reactor being in downstream communication with the fractionation section.
