The National Development and Reform Commission announced on May 11 the "Circular on Accelerating the Opinions on the Structural Adjustment of the Calcium Carbide Industry" and proposed to completely shut down and phase out the calcium carbide furnace below 5,000 kVA with an annual output of less than 10,000 tons and the discharge is not up to standard. The project, through three years of hard work, adapts the production capacity to the market demand. At present, calcium carbide production capacity exceeds actual demand by a factor of two.
The "Notice" stated that it will strengthen economic measures such as price and taxation and economic leverage, implement the national differential tariff policy for the calcium carbide industry, increase the intensity of pollution discharge, and strengthen the management of licenses. Further study and formulate specific measures for implementing differential electricity prices for enterprises of different scales and different technologies and equipment, and resolutely cancel the preferential electricity price policies introduced by various localities. The calcium carbide furnaces and open type calcium carbide furnaces below 5,000 kVA (1 million tons/year or less) will be eliminated. Electricity is charged at RMB 0.05/kWh.
The eastern coastal areas and regions where energy and resources are relatively scarce are in principle prohibited from building new calcium carbide production projects. Support large-scale PVC production enterprises to establish large-scale calcium carbide production bases in the central and western regions with resource advantages through merger and transformation.
Statistics show that at the end of 2005, domestic calcium carbide production capacity has reached 17 million tons, which is twice the actual output of 8.94 million tons that year, and the production capacity has far exceeded the market demand. According to statistics, projects currently under construction and planned to be put into operation in succession will continue to produce a net increase of 1 million to 1.5 million tons of production capacity each year. According to this increase, the calcium carbide production capacity in 2010 will exceed 22 million tons.
Potassium Tripolyphosphate
Potassium tripolyphosphate (K5P3O10) is a white, odorless, and water-soluble salt. It is commonly used as a sequestrant, emulsifier, and stabilizer in the food industry. It is also used in the detergent industry as a builder and water softener. Potassium tripolyphosphate can help prevent discoloration and improve the texture of processed meat products. It is generally recognized as safe (GRAS) by the US Food and Drug Administration (FDA) and can be used in various food applications, including canned meats, seafood, and poultry products.
Potassium tripolyphosphate (K5P3O10) is a white crystalline powder that is commonly used as a food additive and detergent builder. It is a type of tripolyphosphate, which is a polyphosphate compound that contains three phosphate groups.
In food, potassium tripolyphosphate is used as a sequestrant, which means it binds to metal ions and prevents them from reacting with other ingredients in the food. This helps to maintain the texture and flavor of the food. It is also used as a preservative, as it can inhibit the growth of bacteria and fungi.
In detergents, potassium tripolyphosphate is used as a builder, which means it helps to soften hard water and improve the effectiveness of the detergent. It can also help to prevent the redeposition of soil onto fabrics during the washing process.
However, the use of potassium tripolyphosphate has been controversial due to its potential environmental impact. When released into waterways, it can contribute to eutrophication, which is the excessive growth of algae and other aquatic plants that can deplete oxygen levels and harm aquatic life. As a result, some countries have restricted or banned the use of tripolyphosphates in detergents and other products.
