Abstract

The slurry jet technique is widely used for flue gas desulfurization, whereas the increase in its absorption efficiency is required to meet the increasingly strict exhaust emission standards. In this work, we developed a Venturi-type slurry jet nozzle to improve the efficiency of flue gas desulfurization. As anticipated, the absorption efficiency of SO2 can be enhanced by increasing the liquid flow rate (impinging stream) and reducing the nozzle throat diameter, which increases the surface area for gas absorption. Interestingly, the absorption efficiency can be further improved by introducing Venturi-generated bubbles. At a constant liquid flow rate of 1 m3/h and pH of 7, using an 8 mm Venturi injector instead of an 8 mm traditional nozzle results in an approximate 6.3% increase in absorption efficiency. The mass transfer coefficient \({K}_{G}a\) for the former is 1.15 times higher than that for the latter. This study provides a simple and feasible caustic scrubber transformation method for the industrial flue gas desulfurization.
