Abstract

1,250,615. Extracting aromatics. R. L. IRVINE. 1 Aug., 1969 [2 May, 1968], No. 20945/68. Heading C5E. The aromatics fraction of a hydrocracking product is extracted with a solvent of boiling- point below that of the hydrocrackate by introducing the latter into an extractor as the upper feed, introducing a middle feed comprising benzene and heavier hydrocarbons and some toluene, derived by distillation from a light reformate, introducing as a bottom feed a reformate fraction which is constituted by toluene and heavier fractions and is free from cyclohexane, and passing the aromatics-rich extract to an aromatics-solvent splitter. The upper feed may boil up to 410‹ F. if diethylene glycol solvent is used, or up to 425‹ F. for a sulpholane; methyl pyrrolidone is an alternative solvent. The bottom feed preferably has an end-point not exceeding 318‹ F. The aromaticssolvent splitter may be a steam heated reboiler. Water extraction is used for solvent recovery in both the raffinate and extract products.
