Nicknames of calcium hydroxide: slaked lime, hydrated lime.Production method of calcium hydroxide: The finished product is obtained by digesting calcium oxide with water and drying, sifting and windpicking.Physical and chemical properties of calcium hydroxide: strongly alkaline. Placed in the air, it gradually absorbs carbon dioxide and becomes calcium carbonate. Slightly soluble in water, soluble in acid. With a density of 22.4g/cm3, its clarified aqueous solution is a colorless odorless alkaline transparent liquid with a PH value of 12.4.
The main reasons why calcium hydroxide is used in flue gas desulphurization include its high efficiency, economy and environmental friendliness.
Calcium hydroxide reacts with sulfur dioxide to form calcium sulfate, thus achieving flue gas desulfurization . Calcium hydroxide and sulfur dioxide neutralization reaction, calcium sulfate and water, in addition, calcium hydroxide also has the ability to absorb sulfur dioxide, can directly adsorb sulfur dioxide molecules to form calcium sulfate, further improve the desulfurization efficiency . Calcium hydroxide has many applications in flue gas desulphurization including wet desulphurization, dry desulphurization and semi-dry desulphurization.
