A dialyzer is to be used to separate 300 L/h of an aqueous solution containing 0.1 M NaCI and 0.2 M HCI. Laboratory experiments with the microporous membrane to be used give the following values for the overall mass-transfer coefficient K1 in (14-57), for a log-mean concentration driving force:

Ki, cm/min Water 0.0025 0.021 NaCl НСІ 0.055

Determine the membrane area in m2 for 90, 95, and 98% transfer of HCI to the diffusate. For each of the three cases, determine the complete material balance in kmol/h. A sweep of 300 L/h can beassumed.

Ki, cm/min Water 0.0025 0.021 NaCl 0.055
