Rich Solvent, containing Aromatics and Sulfur Compounds, is routed to the Solvent Recovery Column (SRC), where the Hydrocarbons and Sulfur Species are separated, and Lean Solvent is recovered in Columns Bottoms.  The SRC Overhead is hydrotreated by conventional means and either used as Desulfurized Gasoline or directed to an Aromatics Plant.  Lean Solvent from the SRC bottoms is recycled back to the EDC.
