Calcium Carbide Gci

Calcium carbide is a chemical compound with the chemical formula CaC2. It is a grayish-white crystalline solid used in producing acetylene gas in various industrial applications, including welding and cutting torches, and as a fuel for lighting and heating.

Calcium Carbide Manufacturing Process:

Raw Material Preparation: We begin by carefully blending lime (calcium oxide) with coke (carbon) in precise proportions to prepare the charge for production.
Carbothermic Reduction: The prepared mixture is then introduced into an electric arc furnace. Here, a high-temperature electric arc facilitates the carbothermic reduction reaction, transforming the mixture into calcium carbide and carbon monoxide.
Reaction: Within the furnace, the following reaction occurs: CaO + 3C → CaC2 + CO, resulting in the formation of calcium carbide and carbon monoxide gas.
Cooling: Post-reaction, the furnace contents are allowed to cool, solidifying the calcium carbide.
Crushing and Screening: The solidified calcium carbide is then crushed and screened to achieve the desired particle sizes.
Packaging: Finally, the processed calcium carbide is packaged for distribution, ready for its various industrial applications.

Chemical formula

Calcium carbide is made by heating lime and coke in an electric furnace at temperatures above 2000°C (3632°F). The reaction produces calcium carbide and carbon monoxide gas: CaO + 3C → CaC2 + CO

Calcium carbide reacts with water to produce acetylene gas and calcium hydroxide: CaC2 + 2H2O → C2H2 + Ca(OH)2

Appearance: Dark grey
Form: Lumps
75 to 85 % CaC2
15 to 25 % CaO

PH3 %(V/V) ≤ 0.08
H2S %(V/V) ≤ 0.10
Gas yield 285-305L/kg

USES

Production of acetylene gas: Calcium carbide produces acetylene gas through a chemical reaction with water. Acetylene gas is used as a fuel for welding and cutting torches and as a raw material for making various chemicals.

Production of synthetic rubber: Calcium carbide is used as a raw material in the production of synthetic rubber, which is used in the manufacturing of tires, belts, hoses, and other industrial products.

Production of polyvinyl chloride (PVC): Calcium carbide is used as a raw material in the production of PVC, a common plastic used in a variety of products, including pipes, wire insulation, and vinyl flooring.

Production of acetylene-based chemicals: Acetylene gas produced from calcium carbide is used as a raw material in making chemicals such as vinyl chloride, acrylonitrile, and other specialty chemicals.

Desulfurization of iron and steel: Calcium carbide is used in desulfurizing iron and steel, helping to remove impurities and improve the quality of the final product.

Welding and cutting: Acetylene gas produced from calcium carbide is used as a fuel gas in welding and cutting torches, making high-temperature flames for metalworking applications.

Lighting: Acetylene gas produced from calcium carbide can be used in gas lamps and lanterns for lighting and heating applications, particularly in areas without electricity.
