Gas holdup measurements for air and water have been made using the 13 inch acrylic column to test the equipment. The preliminary results indicate all the equipment and the experimental techniques work satisfactorily. Methods to dissolve carboxyl methyl cellulose and polyethylene oxide in water in large enough quantities for use in the 13 inch column have been devised. Preliminary analysis indicates the use of porous plates as a gas distributor in the 6 inch column yield gas holdup values very close to 0.25 at the bubble and bubble-slug transition. A number of porous plates were used of different material, pore size and thickness.
