The Ultimate Solution for Large-Capacity Flue Gas Treatment<\/h2>\n

Der BLSHSTL1W\/230W Series Limestone-Gypsum Flue Gas Desulfurization (FGD) System<\/strong> is universally recognized as the most mature, reliable, and widely deployed technology for heavy industrial emission control. By utilizing a highly reactive limestone (CaCO3<\/sub>) slurry, it washes and neutralizes massive volumes of flue gas, efficiently capturing sulfur dioxide (SO2<\/sub>) and converting it into stable, marketable calcium sulfate dihydrate (gypsum).<\/p>\n

Engineered to seamlessly handle ultra-high sulfur loads (up to 5,000 mg\/Nm\u00b3) and massive airflow capacities (up to 2,300,000 m\u00b3\/h), this series is the definitive upgrade for utility power plants and heavy metallurgical facilities.<\/p>\n

As a high-performance, cost-optimized alternative to premium global benchmarks like the General Electric (GE) or Mitsubishi Heavy Industries (MHI) wet scrubber systems, our BLSHSTL series delivers identical or superior desulfurization efficiencies while dramatically optimizing both CapEx and lifecycle OpEx.<\/p>\n<\/div>\n

3. Reaction Mechanism<\/span><\/p>\n

How It Works: The Chemical Principle<\/h2>\n

Flue gas enters the absorber from the bottom and makes counter-current contact with the downward-sprayed limestone slurry. The gas is cleaned, demisted, and discharged, while the sulfur compounds are permanently locked into solid crystal structures.<\/p>\n<\/div>\n

\n
\n

Gas-Liquid Absorption<\/h3>\n

ALSO2<\/sub> and SO3<\/sub> in the flue gas are absorbed by water in the slurry droplets, initiating the acidification of the liquid phase.<\/p>\n

Limestone Dissolution & Neutralization<\/h3>\n

The calcium carbonate dissolves into active ions, which undergo complex ionic reactions with the acidic sulfite to form calcium sulfite.<\/p>\n

Forced Oxidation & Crystallization<\/h3>\n

Oxygen injected into the slurry tank forcefully oxidizes the unstable calcium sulfite into calcium sulfate, which crystallizes into recyclable gypsum.<\/p>\n
