Document Summary
Since the mole fraction in the initial feed was 0. 12 (12%) which is higher than 0. 1 (10%), the solution is non-dilute; therefore, the equilibrium relationship as well as the operating relating was assumed non-linear by to henry"s law. Accordingly, the design can be procedure to determine the dimensions of the tower base on the equations representing the equilibrium curve. Some of the important heuristics and design considerations used during the design process are provided: The ratio of the tower diameter to packing diameter should be greater than 15 to 1, i. e. The optimum (l/v) flow should be in the range from 1. 2 to 1. 5 times the minimum (l/v), i. e. () = 1. 2 1. 5 () In case of low pressure drop, the tower should be less than 0. 9 m to suit structured and random packings. Packed tower should operate near 70% of flooding. Assume the operating pressure is similar to the atmospheric pressure (p = 1atm) with negligible pressure drop.
