Products Description
The effects of solution pH and temperature on the dissolution characteristics of calcium carbide slag in wet flue gas desulfurization were studied in a kettle reactor using hydrochloric acid to simulate SO2 in flue gas. The experimental results show that the lower the solution pH, the faster the dissolution rate of carbide slag, and the higher the final dissolution rate achieved under experimental control conditions; the dissolution rate increases with increasing temperature. The final dissolution rate of carbide slag under different working conditions was measured experimentally, and an empirical formula for the dissolution characteristics of carbide slag was obtained.
