Gas Liquid Absorption

1) Prepare 20 liter of 1N NaOH solution in a feed tank.

2) Check the concentration of the feed solution by titration against 0.1 N HCl.

3) Fill the bubbling pot with 3 liters of above prepared solution.

4) Check the concentration of the bubbling pot solution by titration against 0.1N HCl.

5) Set the flow rate of NaOH solution to 10 L/H.(you can set any point from slider)

6) Set the flow rate of carbon dioxide gas to 90 L/H. (you can set any point from slider)

7) Set the flow rate of air to 30 L/H.

8) Take sample at 10, 20, 30 minutes from column outlet and bubbling pot outlet.

9) Titrate the sample collected, using phenolphthalein indicator against 0.1N HCl.

10) Titrate the same sample, using methyl orange indicator against 0.1 N HCl

11) Calculate the balance on NaOH and CO2.
