IONIC LIQUID TREATMENT OF VACUUM SLOP CUT TO INCREASE HYDROCRACKING FEED |
| 摘要 |
A process and apparatus for increasing vacuum gas oil recovery from a vacuum column are described. The process includes separating a residue crude oil stream from a crude oil separation column in a vacuum column into at least one vacuum gas oil fraction, and a contaminant-rich slop fraction containing at least one contaminant; contacting the contaminant-rich slop fraction with a lean ionic liquid in a contaminant removal zone to produce a mixture comprising a contaminant-lean slop fraction and a rich ionic liquid comprising at least a portion of the at least one contaminant; and separating the mixture to produce a treated slop effluent comprising the contaminant-lean slop fraction and a rich ionic liquid effluent comprising the rich ionic liquid. |

1. A process for increasing vacuum gas oil recovery from a vacuum column comprising:
separating a residue crude oil stream from a crude oil separation column in a vacuum column into at least one vacuum gas oil fraction, and a contaminant-rich slop fraction containing at least one contaminant; contacting the contaminant-rich slop fraction with a lean ionic liquid in a contaminant removal zone to produce a mixture comprising a contaminant-lean slop fraction and a rich ionic liquid comprising at least a portion of the at least one contaminant; and separating the mixture to produce a treated slop effluent comprising the contaminant-lean slop fraction and a rich ionic liquid effluent comprising the rich ionic liquid. |
