A discussion is presented of the analytical/theoretical treatments involved in the dynamic bubble disengagement technique. The methods used to estimate the size distribution of gas bubbles in a gas-liquid reactor have been generalized. It is demonstrated that the accuracy of the technique is dependent, among other factors, on the analytical forms of the size distributions used in the estimation procedure. An experimental verification of the validity of the technique indicates clearly that the dynamic bubble disengagement technique can provide satisfactory estimates of the relative bubble-size distributions in flotation columns.
