Question: Fresh feed containing 55.0 wt% A and 45.0 wt% B flowing at 100.0 kg/h enters a separator that removes a portion of pure component

Fresh feed containing 55.0 wt% A and 45.0 wt% B flowing at 100.0 kg/h enters a separator that removes a portion of pure component

Fresh feed containing 55.0 wt% A and 45.0 wt% B flowing at 100.0 kg/h enters a separator that removes a portion of pure component A only as a bottom product. The top product stream of the separator contains 10.0 wt% of component A and the balance is B. A small part of the separator product stream is recycled and joined in the fresh feed stream. The other portion is purged. The separator is designed to remove exactly two-thirds of component A fed to it (not the fresh feed). The recycle loop is used to achieve this goal. Compute all unknown stream flow rates and compositions. A,B A,B MIXER Identify the correct answers (A)No of unknowns are 4 (B) No of unknowns are 6 (C) Tie substance is A (D) Purge flow rate is 50 kg/hr SEPARATION A,B UNIT A A,B PURGE A,B
