Unformatted text preview: Question 2 A countercurrent absorption process is to be used to recover solute A from an inert gas. The concentration of A is reduced from A Y = 0.285 to A Y = 0.05 by contacting the gas with pure solvent. . The solubility of the solute in the solvent can be described by y A = 0.4 x A . a) What is the minimum solvent to gas ratio (solute-free basis) for the given separation? b) Determine the number of equilibrium stages required if the actual solvent to gas ratio (solute-free basis) is 1.2 times the minimum value....
