Abstract
An apparatus and process is disclosed for hydroprocessing hydrocarbon feed in a hydroprocessing unit and hydrotreating a second hydrocarbon. A warm separator sends vaporous hydrotreating effluent to be flashed with liquid hydroprocessing effluent to produce a vapor flash overhead that can be recycled to the hydrotreating unit to provide hydrogen requirements.
Claims18
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.
