Calcium carbide is the basis for a great number of manufacturing industries; i.e. calcium cynamide, oxyacetylene welding, pharmaceuticals, sodium cyanide for ore treatment of gold, Food, Synthetic rubber, Plastic, acetic acid, PVC, etc. It is used as a basic raw material for fertilizer industries.
We have emerged as the leading acetylene plant manufacturers in countries such as Saudi Arabia, Qatar, Oman, UAE, Nigeria, Yemen, Bolivia, Brazil, Bolivia, Peru, etc. Basic principle. Acetylene is produced as result of chemical reaction between calcium carbide and water.
Calcium carbide (CaC 2) is the raw material for acetylene and calcium cyanimide.Today it's mainly used in the chemical industry and as a desulfurization agent in steel production. We received significant orders from Guodian Younglight and Junzheng Energy in Inner Mongolia/China, totalling ten furnaces.
Commercial calcium carbide varies in colour from Steel-grey to reddish brown, depending on impurities and the method of manufacture. It is made from lime and coke in the electric furnace at temperature of 2200 - 2500oC, using large amount of electric power. Industrial calcium carbide is about 80% pure remaining is calcium oxide and 2-5% other

Calcium carbide works best when used on large, vigorous plants in good health. Forcing pineapple blooms stresses the plant and may damage unhealthy specimens, resulting in small fruit on small plants.
On reacting with the water, the calcium carbide forms slurry of calcium carbonate, which deposits at the bottom of the chamber. At regular intervals, the reaction must be stopped to remove the deposited slurry. The slurry is removed from the chamber and pumped into a pond, where calcium carbonate gets separated and the water is drawn off.
Aug 03, 2015· Calcium carbide is generated by the carbothermic reduction of lime (CaO) at 2000C. Lime can be produced by reducing limestone (calcium carbonate) in a furnace at 900C-1000C. Once lime has been produced however, one does not need to continue to harvest more limestone to keep making acetylene. The reaction of calcium carbide with water produces ...
Small Scale Calcium Carbide Plant In Ethiopia. applying calcium carbide to induce flowering in pineapple,place 0.8-1.0 gram of calcium carbide in the whorl of the plant (the opening at the very top) at sunrise (figure 1). on nights with dew, the whorl will contain a little water, which makes the calcium carbide even more effective. cool cloudy days are the best days for calcium carbide ...
The Portable Acetylene Plant is designed for small capacity acetylene users Eliminating acetylene cylinders renting. The rated plant capacity is from 1 kg/hr to 6 Kg/hr using USA/UK grade calcium carbide depends on model selected.

Among the eight plants in the integrated production train is a 950,000 t/a calcium carbide smelter, including four 90 MW Hatch furnaces. Additionally, near Xining, QSLIC's Haina subsidiary has developed an integrated facility for the production of cement and PVC with intermediate calcium-carbide production, including one 90 MW Hatch furnace.
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 ...
Alibaba.com offers 1,496 calcium carbide steel plant products. A wide variety of calcium carbide steel plant options are available to you, such as local service location, key selling points, and condition.
plant. In contrast, most existing calcium carbide plants in China have major off-gas and fugitive emissions. Fugitive emissions in these applications are often a consequence of manual handling of feed and especially the fume emanating from the calcium carbide tapping operation. These operations are typically a source al-
Oct 09, 2017· Calcium Carbide for Acetylene Production. Acetylene is a combustible gas with a distinctive odor. It is used as a raw material for the production of several organic chemicals, as well as a fuel component in metal cutting, and oxy-acetylene welding.Today, acetylene is also used in the production of several plastics.
Medium Pressure - Calcium Carbide - Acetylene Plants. Rexarc produces a wide range of products for acetylene generator applications. From individual, point-of-use, through industrial scale cylinder filling and pipeline applications, a solution for your acetylene need is available through Rexarc.
One pound of calcium carbide could produce about 4.5 cubic feet of acetylene, making it cheaper to fuel lighting than oil, kerosene or "city gas". It also creates a brilliant white light, much brighter than with the other fuels available. Acetylene wasn't used for just lighting in buildings.

The CO gas will in most plants be utilised as energy. 1.8 tonnes CO 2/tonne calcium carbide will be released in the production process. In addition, 1.1 tonnes CO 2/tonne calcium carbide will be released when the carbide is used. The CO 2 emissions may be lowered by utilising the gas when producing dicyanodiamide from carbide (Olsen 1991).
