Abstract
An apparatus and process is disclosed for hydroprocessing hydrocarbon feed in a hydroprocessing unit and hydrotreating a second hydrocarbon. The hydrotreating effluent is mixed with hydroprocessing effluent and together fractionated.
Claims18
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.
