Extracted text: A continuous distillation column is to be used to separate a 3-component mixture of acetic acid (AA), water (W) and Benzene (B), and a trial run gave the data below (mass basis). The data for the benzene in the feed (which consists of AA, W and B) was not taken because of an instrument malfunction. Use a degree of freedom analysis, and then calculate the benzene flow in the feed in kg/h. Waste 10.9% AA 21.7% W 67.4% B Aqueous Solution (containing 80% AA + 20% W) B (data not available) Product 350 kg/h pure AA Answer: B in feed 311 kg/h CHEE 221 35
