Gas (A) is dissolved in a liquid solvent (S) with a composition of 21 % by mole. The solvent is stripped to remove the gas from it using air containing 1.5 mol % A. It was found that k equals 0.015 gmol/cm.s, ky equals 0.06 gmol/cm.s. Consider the following cases of equilibrium relation: a) Linear equilibrium relation: YA 0.32XA b) The following equilibrium data generated experimentally: = X 0 0.02 0.04 0.06 0.08 y 0.0000 0.0031 0.0068 0.0110 0.0161 0.18 0.1 0.12 0.14 0.16 0.0221 0.0291 0.0372 0.0464 0.0570 0.2 0.0688 Calculate the following: 1.
