Q1 (50 points) We wish to flash distill an ethanol-water liquid mixture that is 20 wt% ethanol and has a feed flow of 2000 kg/h. Feed is at 224C. The flash drum operates at a pressure of 1 kg/cm. Data: Cple = 38.75 kcal/kmol.C (at 112C), CpLw = 18.0 kcal/kmol.C, MW. = 46.07, MWw = 18.02 E 1. Identify and define the problem to show which solution method is more appropriate for solving this problem. (10 points) [Identification (5) + answer (5)] 2. Apply the suitable mathematics and engineering basic equations to formulate and model the problem and solve it to find the temperature inside the drum.
