Homework 1 Problem 6 SuperPro Designer™ Aspirin 20 points possible due Friday September 2, 2011 Grader: Israel Problem Statement: Aspirin is manufactured batch wise from salicylic acid and acetic anhydride . The reaction stoichiometry is defined as C 7 H 6 O 3 + C 4 H 6 O 3 C 9 H 8 O 4 + C 2 H 4 O 2 with an estimated kinetic rate expression of r Aspirin = k[C 7 H 6 O 3 ][C 4 H 6 O 3 ] where the pre exponential factor (k) is equal to 0.0059 m 3 /mol · s and the activation energy is 3 e6 J/kmol. A typical process consists of a 2 m 3 reactor charged with equal molar amounts of salicylic acid and acetic anhydride . The reactor is kept at atmospheric pressure and 350 K. All components are heated to 350 K before being introduced into the system, where the temperature is held constant. Determine the mass of salicylic acid remaining after the reaction has gone for 2 hours. Method of Solution: Use the RBATCH unit in AspenPlus to simulate the batch process. Solution: 1) Open the SuperPro Designer TM program and start a new process file. 2) Select “Batch Mode” and click OK.
