Key parameters for calculating bubbling degassers

Physical desorption, achieved through water bubbling in a free volume, is a fairly effective method for removing dissolved gases, particularly carbon dioxide. Bubbling degassers are characterized by their technological effectiveness, simple design, and reliable operation regardless of the season. In some cases, studies of bubbling plants are theoretical in nature and don’t take into account most of their physicochemical composition parameters and design features of the units. As a result, the calculation equations become approximations for laboratory data or recommendations with additional conditions. Physical phenomena, as they need to be described during bubbling for practical application, are explained by the π-theorem or the experimental design method. A summary of theoretical and experimental data for determining the calculating parameters of bubbling degassers let us conclude that using the diffusion coefficient is inappropriate. In the absence of data on the desorption coefficient, we recommended to use the water-air ratio and the contact time, depending on the expected effect of carbon dioxide removal, as determining parameters for calculation.
