Patent ID: 8475745

Claim:
A hydrocracking and hydrotreating apparatus comprising: a first compressor on a make-up hydrogen line to provide a first compressed make-up hydrogen stream in a first compressed make-up hydrogen line; a split in communication with first compressor for splitting said first compressed make-up hydrogen stream between a first split line and a second split line; a second compressor on said first split line to provide a second compressed make-up hydrogen stream; a hydrocracking reactor in communication with a first hydrogen line and a first hydrocarbon feed line for hydrocracking a hydrocarbon stream to lower boiling hydrocarbons transported in a hydrocracking effluent line, said hydrocracking reactor being in communication with said first split line; a hydrotreating reactor in communication with a second hydrogen line and a second hydrocarbon feed line for hydrotreating a diesel stream to produce a hydrotreating effluent in a hydrotreating effluent line, said hydrotreating reactor being in communication with said second split line; said hydrotreating effluent line in communication with said hydrocracking effluent line; and a fractionation section in communication with said hydrotreating effluent line and said hydrocracking effluent line.
