Column: 6" I.D. Corning glass pipe - 2-6 ft. sections with a liquid distributor plate at the top, a redistributor plate and support plate between the sections, a support plate at the bottom of the vertical glass pipe

Pump: Oberdorfer Model 109 MB, 30 gpm at 30 ft. of head (water)

Rotameters: air, model 1A3555, SCFM of air at 8.1 psig, 70° F

CO2, model 1A35555, SCFM at 14.7 psia, 70° F

water, model 1A3555, 100% = 21.6 gpm at specific gravity = 1.0

NOTE: Procedures for correcting the rotameter reading for conditions different than the calibration conditions are given on the reference link [click here].

Tank: stainless steel, nominal 200 gallon capacity

Gas Analyzer:

HP 5890 Gas Chromatograph with thermal conductivity detector and integrator

Packing Heights: 5.5 ft. each section

Packing: top section -- structured packing, flexipac type

bottom section -- dumped packing, 5/8 polypropylene flexirings

The raw data and worksheets should at least contain the following information:
- differential pressure for top-middle and middle-bottom
- temperature of entering gas and liquid
- top, bottom and middle CO₂ gas concentration
- air, CO₂, water rotameter readings
- air, CO₂ water flow rates, V_g, L, G.
- properties of water and gas
- number of moles transferred
- mole fraction of CO₂ in the outlet water
- equilibrium liquid mole fractions of CO₂
- D X_lm
- K_La, 1/K_La, Sc, Sc ^1/2, (L/ m), (L/m )^.72
