ABSTRACT:
An apparatus for separating a first component of a process stream from a second component of a process stream in a single vessel has been developed. The single vessel apparatus has a membrane contactor dividing the vessel into an upper portion and a lower portion where the membrane contactor is a material providing selective permeation of fluid components and restricting passage of at least one component to the upper portion of the vessel, and a plurality of vertically spaced apart distillation contactors disposed within the vessel for vapor and liquid distillation located in the lower and/or upper portion of the vessel. The benefit is the production of a process stream that is of high first component purity at reduced capital equipment costs.
