  • Apparatus for removing heavy polynuclear aromatic compounds from a hydroprocessed stream
    Patent number: 8852404
    Abstract: An improved apparatus strips HPNA's from hydroprocessed streams in a fractionation column having a split shell configuration. Only one vapor stripping feed is required to the split shell of the fractionation column. The resulting reduction in steam requirement provides a superior fractionation in the column.
    Type: Grant
