Shanxi carbide industry enters the key period of adjustment

Shanxi Province, once the leader in the industry of calcium carbide in China, failed to optimize and upgrade the industrial structure of calcium carbide in time and accelerate the extension of the industrial chain. As a result, the enterprise stuck to a single product structure for a long time, the comprehensive utilization rate of resources and energy was low, and the sustainable development of the industry fell into a passive situation. Under the national policy of eliminating backward production capacity and high pressure, the prospect was increasingly bleak. How to transform Shanxi carbide industry? On December 6, Li Sanwen, Secretary General of Shanxi carbide Association, said frankly in an interview: "backward production units of Shanxi carbide are common, and the industry is facing great adjustment. In the future, the calcium carbide industry needs to save energy and reduce consumption, improve energy utilization, vigorously develop circular economy, optimize and upgrade the structure of calcium carbide furnace as soon as possible, and strive to expand the diversified development of downstream industry. "

After several years of elimination of backward calcium carbide production capacity, many small-scale calcium carbide production enterprises that do not conform to the policy have been forced to shut down. Since the 11th five year plan, Shanxi has closed and eliminated all calcium carbide furnaces under 6300 KVA, open calcium carbide furnaces, and calcium carbide furnaces with substandard discharge, with a total of 1.7392 million tons of backward calcium carbide production capacity eliminated. 85% of carbide enterprises were eliminated. Carbide production in the country's ranking also slipped from the first to 10 outside. According to Li Sanwen, by the end of this year, Shanxi will also complete the elimination of 20 calcium carbide furnaces with single furnace transformer capacity less than 12500kVA, involving 15 enterprises, and the output of calcium carbide will be 311000 tons. Li Sanwen told reporters that many downstream enterprises of calcium carbide reported to the association that the industry of calcium carbide is a high energy consumption and high pollution industry, but it is also a basic raw material industry in China, which needs to be consolidated, but is indispensable. "To eliminate the backward production capacity of calcium carbide, we must pay attention to the problem of regional balance. We can't cut all the calcium carbide enterprises in a region."

Many downstream business owners are outspoken. In fact, China's "calcium carbide access conditions (2007 Revision)" has mentioned that it is encouraged to build new calcium carbide production units and large-scale industrial enterprises, so as to improve the comprehensive utilization efficiency of resources and energy. For many years, the development of calcium carbide industry has been following the direction of: promoting the merger and reorganization of enterprises, forming a large production base of calcium carbide and supporting products. At the same time, improve the industrial scale of recovery and comprehensive utilization of tail gas from calcium carbide furnace. In recent years, new large-scale PVC enterprises in the western resource rich areas are all supporting carbide production, and a number of typical circular economy development models have emerged in the industry. For example, Xinjiang Tianye, Xinjiang Zhongtai, Liaocheng Xinfa, Ningxia yinglite, Western chlor alkali, Shaanxi Beiyuan, Inner Mongolia Junzheng, Yili and Jilantai. There are also many enterprises across the country, through the construction of circular economy projects, to extend the industrial chain and realize the resource utilization of carbide furnace tail gas, slime, dust and carbide slag, which set an example for Shanxi carbide industry.

For example, Inner Mongolia baiyanhu Chemical Co., Ltd. has been developing calcium carbide alone in the past, once becoming the largest calcium carbide enterprise in China. But a single carbide product structure has also made enterprises suffer a lot in previous national elimination and adjustment. Several smaller carbide furnaces have been eliminated and dismantled, which makes them heartache. They realized that only by expanding the production scale of calcium carbide, it is difficult for enterprises to become bigger and stronger, and they must develop into high-end industries. After a lot of investigation, the development of polyvinyl alcohol series fine chemical products was selected. It is quite different from these enterprises that Shanxi calcium carbide industry has not made effective adjustment, so the country will be in trouble as soon as the adjustment policy is issued. There are also some enterprises on the road of "great escape from victory". For a period of time, they moved to Inner Mongolia, Shaanxi, Gansu and other provinces to build blast furnace calcium carbide. During the peak period, there are more than 50 calcium carbide enterprises in Shanxi gathered in the western region, with more than 10 billion yuan of capital falling on calcium carbide, but not a downstream enterprise such as PVC. This also causes Shanxi carbide industry to delay the adjustment time and the development space.

At present, from the perspective of scale, the annual average carbide production capacity of Shanxi carbide enterprises is only 20000 tons, only one enterprise with production over 100000 tons, and the small enterprises with production below 50000 tons account for more than half of the total; from the perspective of technical equipment, there are only two large-scale fully enclosed submerged arc furnaces with advanced technology, effective emission control and comprehensive utilization of resources, and the rest are mostly 10000-50000 tons There are a few open type calcium carbide furnaces less than 10000 tons in operation. In such a severe situation, Shanxi carbide industry is planning to move on. At a recent conference on the province's calcium carbide industry, the whole industry showed a determination to stay alive. According to the conference forecast, by the end of the 12th Five Year Plan, the demand for calcium carbide in Shanxi will reach 4 million tons, and there is still a large development space for calcium carbide industry in Shanxi. With the increasingly strict national industrial policy, the implementation of energy conservation and emission reduction and environmental protection policies, a large number of backward carbide production capacity has been gradually withdrawn from the market, which has freed up capacity and space for the development of new carbide furnace, and will create a more favorable development environment for Shanxi carbide industry. At present, the one million tons (phase I 400000 tons) calcium carbide project of Shanxi Yangmei group and the 500000 tons / year closed calcium carbide furnace project of Shanxi Leixin are major adjustment projects for accelerating the elimination of backward production capacity and realizing scientific strategic layout of Shanxi calcium carbide industry. Shanxi International Energy Group will also explore an intensive, large-scale, recycling and integrated development path in the construction of the world's first power plant cogeneration calcium carbide project in Taiyuan.
