(243c) Quantification of the Effect of Solids in Solution on Gas Evolution Rates

namely gas/liquid phase separation. Rates of gas evolution are a key uncertainty in gas/liquid

separator design. Work is being conducted to gain a comprehensive understanding of gas

evolution kinetics; however, the presence of solids in solution was previously unaccounted for.

The purpose of this project is to develop a simple methodology to quantify the effect of the

addition of solid particulates of varying characteristics (hydrophobicity, density, mass, and

surface roughness) to gas evolution behavior of a supersaturated solution. This study details

the design and commissioning of a cost effective gas evolution experiment with the ability to

determine a gas evolution rate of a system with added solids at ambient pressure. An

experimental setup using club soda as a supersaturated solution employed the displacement of

a liquid to measure evolved gas and calculate gas evolution rates. Experimental trials have

shown that a gas evolution rate increases with increasing mass of a dense hydrophilic solid

introduced to a supersaturated solution. Work on the project is still ongoing.
