According to reports, Mengxi Hi-tech Industrial Park in Inner Mongolia is located in the Etuokeqi area of ​​Erdos City. In 2005, it was listed by the National Development and Reform Commission and other six departments as the first batch of circular economy pilot industrial parks in the country. It was also identified by the Ministry of Science and Technology as the transformation of national new material achievements. Industrialization demonstration base. At present, Mengxi Hi-tech Industrial Park has formed four industrial chains, and the other two industrial chains are also in full swing.
The first industrial chain is Inner Mongolia Mengxi Group's use of coal gangue, aeolian sand, slag, etc. as auxiliary materials to produce 1.5 million tons of high-performance cement. Extracting and recovering the purity of carbon dioxide in the kiln tail gas of cement can achieve food grade carbon dioxide; carbon dioxide can be reused in the production of nano-scale light calcium carbonate and full-degradable plastic. At the same time, the nano-calcium carbonate can be used as an additive for polyvinyl chloride profiles and green coatings in the park to reduce costs and improve performance.
The second industrial chain is to use the 300 million cubic meters of coke oven gas produced by the 700,000-ton/year tamping coke project of Inner Mongolia Shenxi Coal Chemical Company as the fuel of the Kaolin Powder Company to produce high-value added kaolin powder. Coke oven gas can also be sent to Monxi's own power plant for power generation. It is estimated that this project can create a value of 21 million yuan per year for Shenxi Coal Chemical Co., Ltd.; the cost per ton of kaolin powder can be reduced by 400 yuan, and the annual savings can be 5.4 million yuan; the cost per kWh can be reduced by 0.02 yuan, and the annual savings can be achieved. Funds 6 million yuan.
The third industrial chain is to use the coal mines, power plants and coking companies' by-product coal gangue, China Coal and coal sludge 4 million tons/year for the power generation of Mengxi Power Plant. The fly ash produced by the power plant is used to extract alumina, and the waste silicon-calcium slag from the power plant is used as clinker for cement production. At present, the 4 million tons/year coal washing plant has been completed and put into production, and the 400,000 tons/year fly ash extraction alumina project is under construction.
The fourth industrial chain uses the 500 million cubic meters of coke oven gas produced by the Inner Mongolia Shenxi Coal Chemical Company's Phase II project of 1.6 million tons of solid burn coke in the Inner Mongolia Coal Chemical Company to produce methanol, which is used to produce by-products such as crude benzene and sulfur dioxide produced in the coking process. Deep processing, fully extend the industrial chain, improve resource utilization.
The fifth and sixth industrial chains of the park are also under construction. Currently there are more than 30 companies in the park, Shenhua Group, Dongfang Hope Group, Guangdong Hongda Industrial Group, Inner Mongolia Mengxi Group, Inner Mongolia Junzheng Group, Northern United Power, Shuangxin Resources Group, Inner Mongolia Yiyang Logistics, Inner Mongolia Xingguang Coal And other famous companies are among them. Last year, the park achieved a GDP of 6.85 billion yuan, an increase of 20.8% year-on-year; completed social investment in fixed assets of 4.9 billion yuan, and achieved a tax of 660 million yuan, an increase of 28% year-on-year.
In recent years, Mengxi Hi-tech Industrial Park in Inner Mongolia, as the first batch of circular economy demonstration parks in the country, has strictly followed the national industrial policies and environmental protection requirements, and has developed a high technology content, good economic returns, low resource consumption, less environmental pollution, and excellent human resources. The company has initially established six major circular economy industrial chains including comprehensive utilization of coal gangue, comprehensive utilization of carbon dioxide, high-tech materials, coal chemical industry, chlor-alkali chemical industry, and chemical integrated logistics. The industrial structure of the “six-chain and parallel†internal and external macrocycle has been established. Is in its infancy. This is the information that the reporter recently learned from the municipal government of Ordos.
