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.
Claims16
A hydroprocessing and hydrotreating process comprising:
- hydroprocessing a first hydrocarbon stream in the presence of a first hydrogen stream and hydroprocessing catalyst to produce a hydroprocessing effluent stream;
- hydrotreating a second hydrocarbon stream in the presence of a second hydrogen stream and hydrotreating catalyst to produce a hydrotreating effluent stream;
- separating said hydroprocessing effluent stream in a cold separator to provide a vaporous hydroprocessing effluent stream comprising hydrogen and a liquid hydroprocessing effluent stream in a bottoms line;
- mixing said liquid hydroprocessing effluent stream with said at least a portion of said hydrotreating effluent stream to provide a mixture;
- and
- fractionating at least a portion of said mixture.

A hydrocracking and hydrotreating process comprising:
- hydrocracking a first hydrocarbon stream in the presence of a first hydrogen stream and hydrocracking catalyst to produce lower boiling hydrocarbons in a hydrocracking effluent stream;
- hydrotreating a second hydrocarbon stream in the presence of a second hydrogen stream and hydrotreating catalyst to produce a hydrotreating effluent stream;
- separating said hydrocracking effluent stream in a cold separator to provide a vaporous hydrocracking effluent stream comprising hydrogen and a liquid hydrocracking effluent stream in a bottoms line;
- mixing said hydrotreating effluent stream with said liquid hydrocracking effluent stream to provide a mixture;
- and
- fractionating at least a portion of said mixture.

- hydrotreating a second hydrocarbon stream in the presence of a second hydrogen stream and hydrotreating catalyst to produce a hydrotreating effluent stream;
- flashing said liquid hydrocracking effluent stream and said hydrotreating effluent stream to provide a cold flash vapor stream and a cold flash liquid stream;
- recycling said vaporous hydrocracking effluent stream to provide at least a portion of said first hydrogen stream;
- and
- recycling said cold flash vapor stream, separately from the recycle of said vaporous hydrocracking effluent stream, to provide at least a portion of said second hydrogen stream.
