Behavior and Dissolution of Gas Bubble Clouds in an Ocean Environment

摘要

This paper entails a study of the absorption process of carbon dioxide into bothfresh water and seawater. The project investigated the factors which affect the dissolution of CO2 including the concentration gradient between the gas bubble and water, the relative velocity of the bubble with respect to the water, and the combined surface area of carbon dioxide bubbles in contact with the water. A six foot plexiglas tower was used to create a water column through which gas bubbles were percolated. The pH change of the water was measured at both the inlet and outlet of the tower. The amount of dissolved gas was determined by using the first dissociation constant and the concentration of H+ ions in the water. Three series of data were taken. Overall, it was found that water has the ability to absorb CO 2 and further study in this field is recommended. Carbon dioxide,
