Abstract：
 A liquid-column spraying process and system for desulfurizing the flue gas feature use of a pH value regulator to regulate the pH value in desulfurizing area and oxidizing area according to flue gas load for optimal desulfurizing condition. Its advantages are high desulfurizing efficiency and utilization rate of desulfurizing agent, wide adjustable range of liquid/gas ratios, and high quality of hy-product (gypsum).
