ABSTRACT:
The present invention is a process for separating at least a first component from a second component of at least a first stream within a single vessel having at least one distillation zone and an adsorption zone. The invention may be applied to separates an alcohol from a mixture of the alcohol and water, such as separating isopropyl alcohol from a mixture of isopropyl alcohol and water. The invention may be applied to more complex systems such as separating isopropyl alcohol and separating diisopropyl ether from the effluents of each reactor of a two-stage diisopropyl ether production process. The benefit of the invention is a high purity separation process at reduced capital equipment costs.
