Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of Ca C 2.Its main use industrially is in the production of acetylene and calcium cyanamide.. The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC 2 (the rest is CaO (calcium oxide), Ca 3 P 2 (calcium phosphide
The temperatures involved in the production of calcium carbide mean that only professionals trained in the use of the required equipment should attempt to make calcium carbide. Crush the solid calcium carbide in either an open-air setting or inert environment prior to it cooling completely. Failure to do so can lead to an explosion hazard.

On May 2, 1892, in Spray (now Eden), Canadian chemist Thomas L. Willson accidentally produced calcium carbide and acetylene with an electric-arc furnace. In August, Willson applied for a patent for the new process. By 1897, acetylene was competing with electricity in providing lighting, especially in rural areas and those places where gasoline was unavailable.

Calcium Carbide is the premier slag-conditioning and desulfurizing agent for iron and steel; carbide produces acetylene gas a precursor to many specialty chemicals and is a valuable tool for construction; and carbide is crucial in cleaning pollutants from our environment.
Calcium carbide is converted into acetylene in a controlled reaction with water using an apparatus called a generator. Acetylene, which has the chemical formula C2H2, is an extremely useful hydrocarbon due to the energy that is locked up in the triple-bond between the carbon atoms.
Urea production and manufacturing process, reactions and uses. Urea is a very important industrial production which is much used in agricultural field as a fertilizer because urea contains high percentage of nitrogen.Urea dissolves very well in water. Urea is called also as carbamide, which is an organic compound with chemical formula of CO(NH 2) 2.
Calcium carbide is made by heating calcium carbonate and subsequently reducing CaO with carbon (e.g. petrol coke), according to the follow reaction: (1) CaCO 3 → CaO + CO 2 (2) CaO + 3C → CaC 2 + CO (CO + O 2 → CO 2) The process for manufacturing calcium carbide is illustrated in Fig. 3.Limestone is converted to lime in a limekiln, while moisture is removed from coke in a coke dryer.
Calcium Carbide Production Process. Calcium carbide is manufactured by heating a lime and carbon mixture to 2000 to 2100°C in an electric arc furnace. In calcium carbide manufacturing process, Moisture is removed from coke in a coke dryer, while limestone is converted to lime in a lime kiln.
Although acetylene production in Japan, China, and Eastern Europe is still based on the calcium carbide process, the large producers in the United States, Western Europe, and Russia now rely principally on the partial oxidation of natural gas.

subsystems: the calcium acetylide manufacturing process and a subsystem of utilities. The subsystem of the calcium acetylide manufacturing consists of an electric arc (carbide) furnace and a separator of solids wafted by the off-gas from the reactor. Coke with anthracite, lime, and electrode paste are intro-duced into the acetylide furnace.

In China, the dominant process to make VCM is based on acetylene produced from calcium carbide. Coke made from coal and calcium oxide from limestone are heated to over 2000oC to make calcium carbide and carbon monoxide. Water is then mixed with the calcium carbide to make acetylene which reacts with anhydrous hydrogen chloride to form VCM.
Acetylene is commercially generated by the chemical reaction between calcium carbide and water. The reaction generates a significant amount of heat, which must be alleviated to avert the acetylene gas from exploding as in the BDM acetylene gas plants.
