Mechanism of the Degassing Process

The actual degassing process takes place in a liquid, throughout which is properly distributed a set of stable bubbles, and in order to formulate the theory of this process it is required to generalize the principles pertaining to the behavior of the single bubble in an ultrasonic field to this aggregate set of bubbles. The fundamental problem, clearly, is to calculate the degassing rate and value of the quasi-equilibrium concentration on the basis of data on the distribution of the bubbles and their behavior. Such a general statement of the problem, however, is incredibly cumbersome, because the variation of the gas concentration in the liquid is caused by a variety of intrinsically diverse effects; the problem can be intelligently simplified by bearing in mind that true degassing, i.e., the liberation of dissolved gas and the reduction of its concentration in the liquid to values below the equilibrium value, takes place only by virtue of diffusion. It is most important, therefore, to consider this particular effect in application to the stated set of bubbles.
