#2 A constant pressure condenser is used to remove methyl ethyl ketone (MEK) from air. The entering MEK and air stream has a relative saturation of 70% and is at a temperature of 80C and pressure of 3.94 atm. The exiting MEK and air stream will contain 5% of the MEK initially fed to the process. The MEK/air stream is fed at a rate of 5.0 kmol/h.

a) Draw a complete flowchart of the process and perform a degree of freedom analysis. When labeling your flowchart include all known and unknown variables including temperatures and pressures.

b) Calculate the mole fraction of MEK in the entering MEK/air stream and the exiting MEK/air stream.

c) Calculate the temperature of the exiting MEK/air stream.

d) Calculate the ratio of condensed MEK over the amount of MEK fed.

So I have the answers I just don't know how to get there.

Problem 2b: yin= 0.18 kmol MEK/kmol, yout= 0.011 kmol MEK/kmol Problem 2c: T= 5.47 C (approximate) Problem 2d: 95%
