Figure depicts a singlestage chemical exchange process in which a gas flowing from bottom upward is passed over a liquid flowing from top down in a vertical column. The transfer of a chemical from the gas into liquid occurs at rate that is proportional to the difference between the gas and liquid concentrations within the column. The height of the column is metre with a diameter of cm and the packing is of the columns height.
You are given the following values: QG Lmin and QL Lmin cG gm cL gm QG and QL are the gas and liquid flow rates, respectively, and D the gasliquid exchange rate Lmin The operating mass holdup for the packing of the absorber is of the packing bed.
Value of D must be: Lmin
