11.4 Calcium Carbide Manufacturing

The process for manufacturing calcium carbide is illustrated in Figure 11.4-1. Moisture is removed from coke in a coke dryer, while limestone is converted to lime in a lime kiln. Fines from coke drying and lime operations are removed and may be recycled. The two charge materials are then conveyed to an electric arc furnace, the primary piece of equipment used to produce calcium carbide. There

11.4 Calcium Carbide Manufacturing 11.4.1 General Calcium carbide (CaC2) is manufactured by heating a lime and carbon mixture to 2000 to 2100°C (3632 to 3812°F) in an electric arc furnace.

Calcium carbide Wikipedia

Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke at approximately 2,200 °C (3,990 °F). This is an endothermic reaction requiring 110 kilocalories (460 kJ) per mole and high temperatures to drive off the carbon monoxide. This method has not changed since its invention in 1892: CaO + 3 C → CaC2 + CO

Calcium Carbide an overview ScienceDirect Topics

The modern technology used for the production of calcium carbide is based on the reduction of calcium oxide (lime) to CaC 2 by carbon for the overall reaction CaO + 3C = CaC 2 + CO. During this process, impurities such as sulfur and phosphorus, contained in the charge components, are also reduced and dissolved in molten calcium carbide.

US4594236A Method of manufacturing calcium carbide from

Calcium carbide is prepared from a powdered lime material. The powdered lime material, possibly together with a reducing agent, is injected with the aid of a carrier gas into a plasma gas generated by a plasma generator. The heated lime material, together with any reducing agent used and the energy-rich plasma gas, is then introduced into a reaction chamber substantially surrounded on all
