| Summary: | additional variable for mixing effects can be accounted for and the mass transfer coefficient are functions of brine brine concentration. The DST is measured with a SensaDyne brine solutions and bubble sizes from 0.26 mm to 0.66 mm. bubble frequency and brine concentration. The bubble sizes bubbles in the system. This is possible because both DST coefficient is determined as a function of bubble size and concentration and bubble size. Currently, the correlation decreases due to the non-coalescing effects of an increased digital video camera and an imaging program called electrolyte concentration. An increase in surface tension Engineers' (ASCE) reaeration technique, the mass transfer for DST is valid for deionized water up to 8 % by weight in a generalized model. increases the resistance to mass transfer across the bubble interface. By using the American Society of Civil mass transfer column are statistically measured using a measured bubble frequencies, and the bubble sizes in the PC9000 differential pressure tensiometer as a function of predicted by a correlation dependent solely on the DST of produced by the tensiometer are calculated from the should be extended to different column configurations so an SigmaScanTm. The resulting statistical correlation allows sizes in high concentrations of brine to complete the mass surface tension (DST) affect bubble size. The surface tension of a bubble increases as the diameter of a bubble the mass transfer coefficient of a brine solution to be The mass transfer data should be extended to larger bubble This study shows that brine concentration and dynamic transfer characterization.
