Economics of Calcium Carbide Production Processes by

Nov 05 2015Industrial Process Economics Reports About Calcium Carbide Calcium Carbide is a chemical compound mainly use in the industrial production of acetylene and calcium cyanamide in the manufacture of chemicals for fertilizer and in the desulfurization of pig iron cast iron and steel Carbide production processes Acetylene Manufacturing Technology Acetylene is a highly flammable gas which is colorless lighter than air and has a garlic-like odor Being colorless and inflammable gas it is employed as a fuel and a chemical building block It remains unstable in pure form so it is usually handled as a solution The chemical compound with the formula C2H2 a compound of carbon and hydrogen Calcium Carbide Production from Limestone Calcium Carbide Ullmann's Encyclopedia of Industrial Chemistry 7th edition This report presents an up-to-date detailed cost analysis of Calcium Carbide production from limestone and coke In the process limestone is calcinated to lime which reacts with coke in an electric arc furnace producing calcium carbide Acetylene It does not cover the production of calcium carbide or the generation of acetylene from calcium carbide For this reason the industry status section does not include information on calcium carbide plants However a draft copy of the tabulation of calcium carbide manufacturing CiteSeerX — Calcium Carbide ManufacturingSection 11 4 on calcium carbide manufacturing A description of the industry is presented first A process description followed by a discussion of emissions and controls is then presented Following these sections the references that were used to develop the revised

Calcium carbide

Calcium carbide also known as calcium acetylide is a chemical compound with the chemical formula of CaC2 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 CaC2 In the presence of trace moisture technical-grade calcium carbide emits an Calcium Carbide Applications Carbide for Metallurgy In modern steelmaking operations the need for lower sulfur steels demanded by modern continuous casting operations and specialty applications has increased calcium carbide's appeal as a hot metal desulfurizer or as a modifier to the slag to USA A process for leaning calcium carbide yielding between 280 and 300 liters acetylene when reacted with water by using a calcium compound as leaning material which comprises introducing into a calcium carbide melt calcium oxide having a particle size between 1 and 8 mm as a leaning material with the resultant formation of a homogeneous mixture of calcium carbide and calcium oxide and cooling the Calcium Chloride Calcium Chloride (CaCl 2) is an inorganic compound marketed as 36% solution 75-78% flakes or 94-97% granules used for roads de-icing dust control brine refrigeration dehumidification setting time reduction in concrete petroleum oil extraction and food processing

The Conversion of Coal to Acetylene

Mar 16 2013By combustion of the by-product CO produced during the production of calcium carbide or auxiliary fuel in the air to preheat the raw materials to C the carbon consumption and the oxygen consumption for the calcium carbide production can be reduced and thus process energy consumption is further reduced Calcium Carbide Grinding Unit Manufacturing ProcessSilica Sand Manufacturing Process- calcium carbide grinding unit manufacturing process XSM is a professional types of Silica Sand Manufacturing Process manufacturer in sandstone calcium carbide iron grinding and beneficiation processcalcium carbonate making process uksolutions project Acetylene Properties and Manufacturing from Calcium 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 Commercialization of Calcium Carbide and Acetylene Landmark Designation From this beginning calcium carbide and acetylene manufacturing spread around the world Acetylene used first for lighting homes railways mines and marine buoys and then for oxyacetylene welding became one of the foundations of the synthetic organic chemicals industry CO2 emissions in calcium carbide industry An analysis of 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
