Although this chemical enterprise has been built for less than 10 years, its performance has been outstanding. The annual power generation capacity reaches 400 million kilowatts, the output of calcium carbide is 70,000 tons/year, the output of lime and nitrogen is 70,000 tons/year, and the output of dicyandiamide is 18,000. Ton/year, plus the carbon, building decoration materials, etc., this year's output value will reach 400 million yuan. However, what is more interesting to reporters is BMW's environmental protection measures and sustainable development.
When entering BMW Chemicals, the reporter found that the chemical company in the western region was very clean. The spacious factory building is surrounded by green grass and trees. The artificial lake surface, the white marble bridge and the rockery stone in the gate of the factory place make people think that they are in a park; on the east side of the plant area is the cooling tower of the captive power plant, with a thick neck. "It is several tens of meters high. Although it can be seen at power plants all over the country, the "rough neck" of the BMW Chemical Factory area is very special. It is painted in sky-blue, and there are also blossoming white clouds above it. Become a factory site. According to Ma Shaoqing, Chairman of BMW Chemicals, the three-dimensional view of the blue-and-white clouds of the earth-cooled cooling tower was spent for a total of 200,000 yuan. Although a lot of money was spent, it was worthwhile because the environment was priceless. Next to the road under the cooling tower, a circular economy map of BMW Chemicals is displayed. Afterwards, the company can fully understand the company's entire process from raw materials entering the factory to the product's delivery, and how the water-saving and energy-saving and waste treatment are used in the entire process. .
The reporter learned from the interview that at the beginning of 2003, with the approval of the Autonomous Region Development and Reform Commission, BMW Chemicals established two sets of 2×2.5 million kilowatt generating units. This year, the Economic Commission of Ningxia Autonomous Region issued the title “About Ningxia Pingluo BMW Chemical Foundry Co., Ltd. The approval of the feasibility study report for the coke oven gas self-produced power plant project approved that BMW Chemicals use coke oven gas as the main raw material to build a captive power plant. The overall scale of the project is 2×25 million kilowatts. The project began construction in 2005 and will be completed by the end of 2006. The project has the exemplary meaning of recycling and sustainable development. After the project is completed, it can not only solve the problem of power consumption of the enterprise itself, but also provide external heat for power generation. At present, the first phase of the captive power plant has begun to supply heat to the Pingluo County Railway Station and surrounding municipal buildings. After the completion of the second phase of the project, heat will be supplied to the Pingluo Industrial Park. This will save a number of scattered small coal-fired boilers. Reduce soot and sulfur dioxide emissions and protect the local environment.
Furthermore, this self-produced power plant project launched by BMW Chemicals does not use thermal coal, but instead uses coal gangue, a by-product of the coal washing process of local coal companies. Power generation using coal gangue is in line with national industrial policies, and waste can be reused. Reducing the cost of power generation in a company can serve two purposes. Although the exhaust gas generated from coal gangue power generation is much lower than that of bituminous coal, BMW Chemicals still considers how to solve the problem of sulfur dioxide pollution generated in exhaust emissions. With the help of the Ningxia Environmental Protection Agency and power system partners, they invested several million yuan to launch a set of circulating fluidized bed plant, which basically solved the problem of dust removal, achieved an emission compliance rate of 96.6%, and the exhaust gas sulfur dioxide content of BMW Chemicals. It is 50 mg/m3, far below the national standard of 150 mg/m3. When experts from the National Development and Reform Commission visited the company this year, they recognized the environmental protection practices of BMW Chemicals.
Ma Shaoqing, chairman of BMW Chemicals, told reporters: “Environment is an important symbol of an area, a city, and an enterprise's spiritual outlook, cultural taste, and cultural image. We can't just think about the development of our company and ignore the good or bad of the local environment. In Ping Luosheng, in Ping Luochang, in Pingluo to run a business, I don't do anything about future generations." Ma Shaoqing said so, and did so. In the past few years, BMW Chemicals has invested a total of more than 80 million yuan for the construction of circular economy system projects. At present, an industrial chain of meteorite thermoelectric- calcium carbide-dicyandiamide has been initially formed.
In addition to the thermal power plant in Shaoshi, Ma Shaoqing also briefed reporters on several other sustainable development measures of BMW Chemicals. The first is the comprehensive utilization project of calcium carbide furnaces. Calcium carbide is an important raw material for the production of lime nitrogen by BMW Chemicals. This project is to purify gas from closed calcium carbide furnace furnaces and then to the boilers of the Lanshi Power Plant for fuel. This can save annually 18,000 tons of standard coal and reduce dust emissions by 4,200 tons. The waste gas can also be recycled and used as a national debt project approved by the National Development and Reform Commission. The second is the use of dry residue desulphurization projects. Dicyandiamide production process can produce a large number of industrial solid waste residue, the previous practice is the burial process, now with the help of experts, BMW Chemicals will be mixed with solid waste in the power station circulating fluidized bed boiler dry desulfurizer to achieve flue gas desulfurization The purpose is to reduce industrial solid waste emissions while saving 22,000 tons of carbon stone resources. The third is the flue gas extraction CO2 project. The project is to use 8% to 10% of carbon dioxide gas in the flue gas of the thermal power plant of the Panshi Thermal Power Plant and enrich it with physical and chemical methods to replace the traditional process for carbon dioxide production from the carbon calcined carbon stone method, which can reduce CO2 emissions by 20,400,000 cubic meters. Dust emission of 8,000 tons, saving 110,000 tons of carbon resources, coke 18,000 tons, was the Ministry of Science and Technology as a major science and technology projects. The fourth is the water recycling project. The production of BMW Chemicals is inseparable from water. In the past, groundwater was exploited and the high cost of resources threatened the company. Therefore, the company built an industrial wastewater recycling project. The dicyandiamide cooling water was reused in the circulating make-up water of the thermal power plant in the Panshi Thermal Power Plant. After purification, it is used for vermiculite, coal dust reduction and greening, which improves the utilization of water resources.
Due to a good solution to the problems of environmental protection and sustainable development encountered in the course of enterprise development, BMW Chemicals has gradually entered a period of sound development in recent years. Many indicators have reached national or industry standards, and companies have also become cleaner production-oriented enterprises. The company was awarded the title of "advanced enterprise" by the autonomous regional government for several years, and was rated by the bank as "AA-grade credit rating enterprise." On this basis, BMW Chemicals has also established an effective product quality system. In 2003, it passed the ISO9001-2000 international standard quality certification system and obtained the corresponding certificate. The leading product of BMW Chemicals, dicyandiamide, is well sold in more than 60 countries and regions including the United States, Germany, and Japan with excellent quality and stable production capacity, and has been well received by the majority of users.
From the Yinchuan City, the capital of Ningxia Autonomous Region, to the north, it is 50 kilometers north of Shizuishan City, an industrial city on the upper reaches of the Yellow River. On the west bank of this Yellow River, there are Pingluo County where the chemical industry is relatively concentrated. On the south side of Xieheng Bridge in Taixi Town of the county, there is a well-known chemical company in Ningxia Autonomous Region - Ningxia Pingluo BMW Chemical Casting Co., Ltd. (hereinafter referred to as "BMW Chemicals").
