Question:
100 kmoles/h of an air stream containing 2 mol% CO2 is to be scrubbed with 150 kmoles/h aqueous NaOH solution containing 5 mol% NaOH at 25 C and atmospheric pressure. The CO2 content in the gas stream has to be reduced by 95%.
a) Is the concentration of NaOH sufficient to satisfy the condition that the chemical reaction between CO2 and NaOH is irreversible. Provide a quantitative answer. For the packing used: HG = 0.3 m and HL = 0.15 m. Assume dilute solutions and ignore changes in the fluids’ flow rates.
b) Calculate the height of packing.
