Abstract
An experiment on laser diagnostics of gas bubbles moving in aqueous solutions of different electrolytes has revealed that efficient suppression of gas bubble coalescence (collapse) occurs at certain concentrations of cation−anion pairs. It is experimentally proven that there is an optimal ion composition at which the coalescence is suppressed in a wide range of velocities of gas particle flow through a column with liquid. It is shown that the threshold ion concentrations corresponding to the onset of coalescence suppression decrease with an increase in the external pressure in the liquid. The results obtained can be used in oil production technologies to solve the problem of burning associated oil gas in torches.
