Fresh feed containing 55 wt% A and 45 wt% B flowing at 100kg/henters a separation system that removes a portion of pure componentA only, as a bottom product. The top product stream (tops) of theseparator unit contains 10 wt% of componenet A and the balance isB. A small part of the tops stream is recycled and mixed with thefresh feed stream- the remainder of the tops stream is purged. Thesepartor is designed to removed exactly two-thirds of component Athat is fed into it. Determine the recycle ration (that is theratio of the flow of the recycle stream to the flow of the freshfeed stream).
