This problem is based on Felder and Rousseau’s Elementary Principles of Chemical Processes 3 rd Edition Example 9.5 2 Homework 4 Problem 2 Aspen HYSYS™ Multiple Reaction Conversion 20 points possible due Tuesday September 27, 2011 Grader: Alan Problem Statement: Methane is oxidized with air to produce formaldehyde in a continuous reactor, according to the following reaction: CH 4 + O 2 CH 2 O + H 2 O [Eq. 1] A competing reaction is the combustion of methane to form CO 2 , as shown in the balanced reaction below: CH 4 + 2O 2 CO 2 + 2H 2 O [Eq. 2] Conversion of methane to formaldehyde is 30% and conversion to CO 2 is 10%. The reactor is fed two streams: pure methane and air. The two feeds are fed such that there are equal molar amounts of methane and oxygen entering the reactor. If the methane enters the reactor at 25 o C and the air enters at 100 o C, how much heat (kJ/hr) must be withdrawn for the product stream to leave at 150 o C? Method of Solution: The system will be solved using the Conversion Reactor unit in HYSYS TM . Solution: 1) Open the HYSYS TM program and start a new case. 2) Click on the Fluid Pkgs tab of the Simulation Basis Manager . Click Add . Select the UNIQUAC model.

    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.
