| titleOfInvention | Apparatus for the solvent extraction of aromatic hydrocarbons from a hydrocarbon mixture |
| abstract | A multiple stage extractor column for the countercurrent contact of an upwardly moving hydrocarbon phase and a downwardly moving solvent phase is disclosed. The column is particularly useful for the solvent extraction of aromatics from a hydrocarbon feedstock containing C 9 aromatics. The contactor column embodies an upper extraction section comprising a first plurality of perforated extraction trays and a backwash section comprising a second plurality of perforated extraction trays, the upcomer means of said second plurality being of larger cross-sectional area whereby the solvent/hydrocarbon interface at the bottom of the column is more readily controlled. |
