ABSTRACT:
Processes are disclosed for the separation of aromatic hydrocarbons from feedstreams containing mixtures of aromatic and non-aromatic hydrocarbons using extractive distillation with an aromatic selective solvent in order to separate the aromatic hydrocarbons from the non-aromatic hydrocarbons. A side stream comprising the aromatic hydrocarbons and trace amounts of entrained aromatic selective solvent is withdrawn from the extractive distillation column and passed to a cyclone separator to provide a lean solvent stream, a stream comprising the aromatic hydrocarbons. The raffinate is withdrawn as an overhead stream comprising non-aromatic hydrocarbons. Various solvents are disclosed and an especially preferred solvent is sulfolane.
