CHE 3333 - Separation Processes Dr Bui Homework #2 Due: 11:59 PM Thursday, March 11, 2022 Problem 2 (50 points) In developing a new process, it is important to separate two streams of methanol and water coming from other processes using a single atmospheric distillation column. The first stream is 100 moh of a 60mol% methanol and 40mol% water and it is saturated liquid. The second stream is 100 molh of a 40mol methanol and 60 mol% water and it is at the dew point. It is desired to have a molar composition of methanol equal to 95% in the distillate and 5% in the bottoms product. The distillation column operates with a total condenser and a partial reboiler and all the sieve-trays operate at equilibrium. The T-x-y and x-y diagrams of the binary system methanol - water is provided. 1. (6) What is the temperature of the first feed stream (To), the temperature of the second feed stream (Te) 2. (6p) What is the total flowrate of the distillate (D) molh), and the flowrate of the bottom B (mol/h). 3. (10p) Use a reflux ratio of R-1.5. Calculate the values of total molar flow rates (for two phases) in the rectifying section (Vand L), the stripping section (and L) and the middle section (V" and L.) 4. (8) Calculate the minimum reflux for this operation 5. (p) Calculate the number of ideal stages required if each feed is placed at the optimal location: Ne GP). Ny(Up). Nelp). Net (IP). 6. (6p)Calculate the number of stages required if cach feed is placed at the optimal location and the overall Murphree's cfficiency is 50%. N. (pl. tp). Nip). N(p). 7. (sp) Calculate the rate of heat addition in the reboiler? (tender. /hr) The heat capacities of methanol and water in the gas and liquid phase can be considered constant for the temperature range between the normal boiling point of methanol (64.5C) and the normal boiling point of water (100C) C of liquid methanol - 90 J/mol K) of liquid water = 76J/mol K) Cof vapor methanol - 53 1/mol K) C, of vapor water = 36 mol ) AHT of methanol @ 64.5C - 35.200 Jimol AH* of water @ 100C - 40,700 imel Please provide your answers all the calculations in a separate sheet, not just the answers. Also if you need to use graphs multiple times, just copy them so your work is neat and readable to the TAs/graders.
