1、 Technical principles

The limestone (lime) - gypsum wet desulfurization process uses limestone or lime as the desulfurization absorbent. Limestone is crushed into powder and mixed with water to make an absorption slurry. When lime is used as the absorbent, the lime powder is digested and mixed with water to make an absorbent slurry. In the absorption tower, the absorption slurry comes into contact with and mixes with the flue gas. The SO2 in the flue gas reacts chemically with the calcium carbonate in the slurry and the injected oxidizing air to produce gypsum. .

3、 Technical features

Mature process technology and device operation;

The desulfurizer has a wide range of sources, low cost, and low operating cost;

Above desulfurization efficiency, the pH value of the limestone absorption tower is around 5.5, and the pH value of the lime absorption tower is 6-7.

Limestone gypsum desulfurization is a commonly used method for wet desulfurization. The main advantages of limestone gypsum desulfurization method are that it has a wide range of applicable coal types, high desulfurization, absorbent, equipment operation rate, and abundant and inexpensive sources of desulfurizer limestone. Limestone gypsum desulfurization is currently a mature flue gas desulfurization process.
