The question has been set up with all the cuts needed to accurately derive expressions for V(x) and M(x). Using the cuts free body diagrams set up below, derive expressions for V(x) and M(x). If you use the method of cuts then validate your answers using calculus or vice versa.
It is required to treat 130 kmol/hr of chloroform-air feed gas mixture that contains
12% chloroform. It is required to remove 93% of chloroform using 150 kmol/hr of
solvent that contains 99.6% water and 0.4% chloroform. The cross sectional area of the
column is 0.8 m². Calculate the column height using the following data; kx'.a = 1.35
(kmol/m³.s (Ax)), and ky'.a = 0.06 (kmol/m³.s (Ay)), kx/ky = 1.35, and the equilibrium
