A plant is removing a trace of Cl2 from a waste gas stream by passing it over a solid granular absorbed in a tubular packed bed.
At present, 63.2 % removal is being accomplished, but it is believed that greater removal could be achieved if the flow rate were increased by a factor of 4, the particle diameter were decreased by a factor of 3, and the packed tube length increased by 50%. What percentage of chlorine would be removed under the proposed scheme? ( The chlorine transferring to the absorbent is removed completely by a virtually instantaneous chemical reaction.)
