Georgia Institute of Technology Department of Chemical and Biomolecular Engineering Stephane Tcheimou John R Brawley Jason Huang Research Students November 13, 2013 Dr. Clifford L. Henderson Professor ES&T 1226 Dear Dr. Henderson We submit here with a design for the process plant based on the diagram that you have provided for us. After running a financial analysis on the system, we deemed that it would be unwise to implement this design because the plant would lose more money than it would make. Further research would have to be done to better optimize this system as well as changing the initial blueprint for the process. Any question you might have about our report can be directed to any one of us at any time. We would love to get a feedback from you about possible ideas to better this process. Your opinion on the matter would be greatly appreciated.

Abstract Isopropyl alcohol is one of the most commonly used solvent in many settings. It has a low boiling point and relatively non-toxic so it is frequently used in laboratories as a cleaner and an intermediate to produce other compounds. Because of the high demand for the product, a process flow diagram was made for the mass production route of isopropyl alcohol. This report address the estimated cost to build this process plant from scratch. Using an analytical model made on Aspen Plus based on a given model, an economic analysis was performed on every piece of equipment to determine the base cost of the process plant as well as its utility costs. Based on the given model, the total cost of the plant over the course of 30 years would be much higher than the profit that could be made. However many changes will be made to this model to maximize the profit margin as well as to make the product more effectively.

Introduction A process diagram was designed for the synthesis of isopropyl alcohol on the program Aspen Plus based on a given model. The diagram included a reactor, two flash drums, a distillation column, a heater, and pump system. Using the reaction rate data, the reaction rate constant was also found for the reaction under given conditions using linear least square regression. Finally, a financial analysis was done to determine the base cost of the equipment needed for manufacturing isopropyl alcohol as well as all supplementary cost of running the plant for the course of 30 years. It is highly recommended that the design be changed for this process plant due to the constant loss of money.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
