Procedure
1. Prepare 1 molar NaOH solution for liquid feed. Prepare 2 mol% CO2 gas feed.
2. Record base feed conductivity (time = 0)
3. Start vapor feed up the column.
4. Start liquid feed down the column. (Turn on pump 2 after opening valves 6 and 7.)
5. Let column reach pseudo-steady state. Monitor vapor flow rate using anubar. Measure bottoms flow rate by colleting bottoms output for 30 seconds. Monitor pressure drop across the column using anubar.
6. Record conductivity of feed and bottoms streams every two minutes.
7. Take 1 mL samples of entering and exiting vapor streams. Use gas chromatography to analyze CO2 composition in the entering and exiting vapor streams.
8. Change the liquid flow rate after 40% carbonation and continue to record data as specified above.

The weight fraction equivalent of carbon dioxide in the bottoms is calculated from a mass balance on carbon dioxide. The mass equivalent of carbon dioxide in the bottoms is equal to the entering mass of carbon dioxide minus the mass...
