| titleOfInvention | For removing the method and apparatus of pollutent from selective aromatics solvent |
| abstract | The present invention relates to the method and apparatus removing pollutent from selective aromatics solvent.Contacting comprising aromatic hydrocarbons in extractive distillationzone with selective aromatics solvent with the feedstream of non-aromatics, producing the raffinate stream comprising described non-aromatics, and comprising the solvent-rich stream of described aromatic hydrocarbons and described solvent.Distinguish from described solvent-rich stream at after-fractionating, produce the extract stream comprising aromatic hydrocarbons, and comprise the lean solvent stream of described pollutent and described selective aromatics solvent.By at least part of described lean solvent stream of non-aromatics cleaning, produce cleaning solvent stream, at least part of described cleaning solvent stream is introduced at least one in described extractive distillationzone and described after-fractionating district. |
