ChE 2124 Homework #4 Name: Due Tue 19 Feb, 2013 4.1. Text Problem A.24 . 4.2. Text Problem 5.2 4.3. Text Problem 5.4 4.4 Text Problem 5.7 4.5. Below is a set of distillation columns just like one presented in class, except the acetone mol% in stream b 2 is unknown and the mole flow rate in stream d 3 is known. Solve this using the bisection method by a simple process: first guess a mole fraction, x , for acetone, second use it to solve four linear algebraic equations, and third check to see if your calculated stream d 3 ( x ) is close to the target value of 50 kgmol/hr. Use 0.0001 for TolMax . Attach you code and your solution. f= 150 kgmol/hr d 2 d 3 = 50 kgmol/hr b 2 b 3 methanol 53.9% ethanol 39.1% acetone 4.3% water 2.6% methanol 3.7% ethanol 48.1% methanol 1.0% ethanol 10.2% acetone 32.0% water 56.8% methanol 0.2% ethanol 1.8% acetone 22.0% water 76.0% methanol 9.3% ethanol 18.7% acetone 26% water 46%
