The jet bubbling system is defined as a device wherein sulfur dioxide is removed by injecting the flue gas into limestone slurry through the slots.
The major variables of the jet bubbling system are inlet concentration of sulfur dioxide, flow rate, pH, temperature, submergence depth of the spargers in the scrubber.
The objective of the experiment is to determine the effects of above variables on removal efficiency and the relationship between mass transfer coefficient and variables. Also, jet bubbling scrubber was compared with the three different systems for sulfur dioxide removal and we tried to apply experimental results to the scale-up of the process.
The results show that sulfur dioxide removal efficiency increase as pH, gas flow rate and submergence depth increase but decreases with the increase of sulfur dioxide inlet concentration and temperature. The value of overall mass transfer ($K_ga$) in the range of the experiment lies between 4.1 × $10^{-4}$ ~ 16.3 × $10^{-4}$ g mol/㎤ min. atm.
According to the result of the scale-up and cost estimation for 23 mW power plant, total capital investment becomes ＄1,289,665, operating cost being ＄591,863/yr..
