Product Description
Limestone/Lime-Gypsum Wet Flue Gas Desulfurization (WFGD)
The limestone/lime-gypsum wet flue gas desulfurization process utilizes cost-effective and readily available limestone as the desulfurization absorbent. This proven technology effectively removes sulfur dioxide and other pollutants from industrial flue gases.
Process Overview
  • Limestone is crushed, ground into powder, and mixed with water to form an absorption slurry
  • When lime is used as the absorbent, lime powder is digested and mixed with water
  • In the absorption tower, the slurry contacts and mixes with flue gas
  • Sulfur dioxide reacts with calcium carbonate and air, producing gypsum as the final product
  • Simultaneously removes other pollutants including dust, HCl, and HF
  • Desulfurized flue gas passes through a demister and heat exchanger before discharge
  • Gypsum slurry is recovered through dewatering equipment
Key Technology Features
  • Single-cycle spray empty tower structure
  • Mature, proven technology with wide application range
  • High desulfurization efficiency and operational reliability
  • Excellent system availability and performance
  • Significant potential for project cost reduction
