| 20120248009 | PROCESS FOR PRODUCING DIESEL - A process is disclosed for hydrocracking hydrocarbon feed in a hydrocracking unit and hydrotreating a diesel product from the hydrocracking unit in a hydrotreating unit. The hydrocracking unit and the hydrotreating unit shares the same recycle gas compressor. A warm separator separates recycle gas and hydrocarbons from diesel in the hydrotreating effluent, so fraction of the diesel is relatively simple. The warm separator also keeps the diesel product separate from the more sulfurous diesel in the hydrocracking effluent, and still retains heat needed for fractionation of lighter components from the low sulfur diesel product. | 10-04-2012 |
| 20120248010 | PROCESS FOR MILD HYDROCRACKING - A process is disclosed for hydroprocessing two hydrocarbon streams at two different pressures. A hydrogen stream is compressed and split. A first split compressed stream is further compressed to feed a first hydroprocessing unit that requires higher pressure for operation. A second split compressed stream is fed to a second hydroprocessing unit that requires lower pressure. Recycle hydrogen from the second hydroprocessing unit is recycled back to the compression section. | 10-04-2012 |
| 20120248011 | PROCESS FOR HYDROPROCESSING TWO STREAMS - A process is disclosed for hydroprocessing two hydrocarbon streams at two different pressures. A hydrogen stream is compressed and split. A first split compressed stream is further compressed to feed a first hydroprocessing unit that requires higher pressure for operation. A second split compressed stream is fed to a second hydroprocessing unit that requires lower pressure. Recycle hydrogen from the second hydroprocessing unit is recycled back to the compression section. | 10-04-2012 |
| 20120251403 | APPARATUS FOR PRODUCING DIESEL - An apparatus is disclosed for hydrocracking hydrocarbon feed in a hydrocracking unit and hydrotreating a diesel product from the hydrocracking unit in a hydrotreating unit.

| 20120292228 | PROCESS FOR HYDROPROCESSING HYDROCARBONS - 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. | 11-22-2012 |
| 20120292229 | PROCESS FOR HYDROPROCESSING HYDROCARBONS - 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. | 11-22-2012 |
| 20120294772 | APPARATUS FOR HYDROPROCESSING HYDROCARBONS - 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. | 11-22-2012 |
| 20120294773 | APPARATUS FOR HYDROPROCESSING HYDROCARBONS - 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. | 11-22-2012 |
| 20130098803 | PROCESS AND APPARATUS FOR PRODUCING DIESEL - A process and apparatus are disclosed for hydrocracking hydrocarbon feed in a hydrocracking unit and hydrotreating a diesel product from the hydrocracking unit in a hydrotreating unit. The hydrocracking unit and the hydrotreating unit share the same recycle gas compressor. A make-up hydrogen stream may also be compressed in the recycle gas compressor. A warm separator separates recycle gas and hydrocarbons from diesel in the hydrotreating effluent, so fraction of the diesel is relatively simple. The warm separator also keeps the diesel product separate from the more sulfurous diesel in the hydrocracking effluent, and still retains heat needed for fractionation of lighter components from the low sulfur diesel product. | 04-25-2013 |
