Preservation and Use of Calcium Carbide

Calcium carbide is readily attacked by the air and the moisture contained in the generators and consequently decomposes during the storing, with formation of acetylene gas. Aside from the loss, this decomposition is also attended with dangers. One of the oldest methods of preservation is the saturation of the carbide with petroleum.

Desulphurization of Hot Metal – IspatGuru

Oct 16, 2013· The process allows the use of several desulphurization reagents, such as lime, calcium carbide and magnesium, which remove the sulphur in the hot metal by chemical reaction and convert it to the slag. Sulphur rich slag generated during the process is removed immediately after completion of the reagent reaction.

Formation of polyethylene from calcium carbide takes place

Formation of polyethylene from calcium carbide takes place as follows: CaC2 + H2O -> Ca (OH)2 + C2H2 -> C2H4. n (C2H4) -> ( -CH2-CH2- )n. Determine the amount of polyethylene possibly obtainable from 64.0 kg CaCl2 . We will notify on your mail & mobile when someone answers this question.

Solid state formation of calcium carbide

water. The current work investigated a process for the synthesis of calcium carbide via a solid-state reaction route and the general kinetics of the reaction was characterized. The calcium carbide was synthesized by conventional and microwave heating (6 kW, 2.45GHz) of micron-sized calcium oxide and carbon powders in argon.

Beneficiation and Mineral Processing of Calcium Carbonate

Mar 23, 2016· 1) CALCIUM CARBONATE DEPOSITS The solution, transportation, and deposition of calcium and magnesium carbonate give rise to deposits of limestones and dolomite. The calcium is derived from the weathering of rocks and is transported to the sedimentary basins chiefly as the bicarbonate, in part as carbonate and as sulfate.
