3/11/11 Objectives Conduct small scale absorption experiment using CSTR Study how different liquid/gas ratios affect the overall efficiency of the absorption process Using the Murphree efficiency, propose a design of full scale column to reduce CO2 in the flue gas from 20% to 2% 22
3/11/11 Procedures Calibrate pH meter and IR machine Load CSTR with different value of known gas and liquid volumetric flow rate Measure CO2 out, pH, temperature, and pressure For every L/V, calculate Murphree Efficiency 33

What students are saying

• 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.
