Calcium Carbide and Acetylene manufacturing process

Problems of calcium carbide manufacturing process. Calcium carbide plant causes to environmental pollution. Corol and limestone are used to take CaO. This causes to coastal erosion. Energy required for preparing CaC 2 is higher than getting energy by the combustion of C 2 H 2. Generated heat causes to increase the temperature of environment. Cannot transport ethyne (C 2 H 2) easily. Storing ...

Calcium carbide - Wikipedia

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 ...

(PDF) PRODUCTION OF LIME USING LIMESTONE

Limestone is a general term embracing carbonate rocks or fossils; it is composed primarily of calcium carbonate combination of calcium and magnesium carbonate with verging amounts of impurities, the most common which are silica and alumina. In contrast, lime, which is invariable derived from limestone, is always a calcined form of limestone, popularly known as quicklime or hydrated lime ...

Cement Manufacturing Plant - Cement Plant AGICO

Gypsum (calcium sulfate dehydrate) is the most commonly adopted set-retarded material in cement manufacturing plants. It is generally added in a very small amount before the clinker is sent into a cement mill. Its main function is to prolong the setting time of cement otherwise the cement would set within minutes after mixing with water.

Limestone (Industrial) Refer also Dolomite (Industrial)

Limestone is a sedimentary rock composed of calcium carbonate (CaCO 3). Most is formed by the accumulation and subsequent solidification of marine fossil debris, but freshwater limestone deposits are also known. Marble formed by the metamorphism of limestone is an important source of calcium carbonate in South Australia, as is shellgrit, an unconsolidated accumulation of sea shell debris found ...
