Abstract
The process involves the use of two rotary valves to implement Varicol operation of a simulated moving bed apparatus to separate a product from at least one multicomponent feed. In a particular embodiment, paraxylene is separated from a mixture of C8 aromatic hydrocarbons. The use of the Varicol process further enhances the separation of the desired product and provides flexibility with a simulated moving bed apparatus using dual rotary valves.
