Product Description

Product Description

High Specific Surface Area Calcium Hydroxide White Powder 

Reaction Principle

High specific surface calcium hydroxide has the characteristics of large specific surface area and high reactivity, and has been widely used in flue gas desulfurization.Sulfur dioxide (SO2) in smoke is one of the main pollutants. High ratio calcium hydroxide reacts with sulfur dioxide to form calcium sulfite (CaSO3) and water (H2O),Calcium sulfite is further oxidized in air to form calcium sulfate (CaSO4), which is gypsum.

Application Mode

Wet desulphurization: The lime milk slurry made of high ratio calcium hydroxide is sprayed into the absorption tower through the spray device. The smoke enters from the bottom of the absorption tower and makes countercurrent contact with the lime slurry from top to bottom. The sulfur dioxide is absorbed by the slurry and the chemical reaction described above occurs to form calcium sulfite and calcium sulfate. This method has high desulfurization efficiency, up to more than 90%, and can simultaneously remove other acidic gases in the flue gas, such as hydrogen chloride (HCl) and hydrogen fluoride (HF).

Semi-dry desulfurization: high surface calcium hydroxide powder is mixed with a certain amount of water to make a slurry, and then sprayed into the semi-dry desulfurization reactor. In the reactor, the slurry is in full contact with the flue gas, the water evaporates rapidly, and the sulfur dioxide reacts with the calcium hydroxide. Semi-dry desulfurization has a high desulfurization efficiency, generally between 80% and 90%, and the system is relatively simple, and the investment and operating costs are low.

Dry desulphurization: high specific surface calcium hydroxide powder is directly injected into the flue gas pipe or desulfurization reactor. Calcium hydroxide powder reacts with sulfur dioxide in flue gas at a certain temperature and residence time to achieve desulfurization. Dry desulfurization process is simple, no waste water discharge, but the desulfurization efficiency is relatively low, generally about 70%-80%, suitable for occasions where the desulfurization efficiency is not particularly high.
