**E133: Fall 2023 Final Project** |[home](index.md.html)|[assignments](assignments.md.html)|[final project](FinProj.md.html)|[notes and code](notecode.md.html)| You are to optimize the operating conditions for the reactor in the flowsheet given below. ************************************************ * ^ * * | .-. * * | | 5 | * * | '-' * * .-. .-. .-. .-+-. * * | 1 | | 2 | +-------+ | 3 | | | * * '-' '-' | | '-' | | * * ------->------>+ R +-------->+ S | * * ^ | | | | * * | +-------+ | | * * | .-.

The kinetics of the reactions need to be determined. The LabVIEW VI, KinTestData.vi inside of FinalProject.llb will simulate the data you would collect from an isothermal constant-volume batch reactor. The initial total pressure can be set between 0 bar and 10 bar, and the temperature can be set between 300 K and 400 K. The VI normalizes the mole fractions. When you want to output the data, click the Save Data to file button and rerun the VI. The data in the file are tab-delimited text and are in the order: time, propane, propylene, methane, hydrogen. You may analyze your data using any method you desire. The complete flowsheet and your kinetic data will need to be entered in Pro/II. For the final flow sheet the feed stream is 100% propane @ 100 mol/sec @ 300K. The reactor volume is 10 m^3. The separator should be a Stream Calculator (under Utilities), set so that the recovery of methane and hydrogen is 100% in the overhead, the recovery of propylene is 99% in the overhead, and the recovery of propane is 95% in the bottoms. To begin your optimization, evaluate the flowsheet for an isothermal reactor temperature of 300K, 325K, 350K, 375K, and 400K, for both a CSTR and a PFR. In choosing the optimum conditions examine the yield of propylene (the desired product), the flow requirements in the rest of the process, the heat duty of the reactor, and the heat duty in the separator. Your final report should include an explanation of the methods you used, the relevant printouts from Pro/II with the relevant information highlighted or circled, a description of the optimal conditions, and a written assessment of the results. _Bonus Problem_: Replace the Stream Calculator with two distillation columns, the first to separate the hydrogen and methane from the propane and propylene, and the second to separate the propane from the propylene.
