On June 29th, Shanxi Orchid Coal Industry Group Company and China Petrochemical Group Nanjing Chemical Company held a forum in Orchid Clean Energy Company. According to the cooperation agreement, the two parties will build a project with an annual output of 6.5438+0.8 million tons of methanol and 600,000 tons of olefins in Jincheng, Shanxi, with a total investment of 65.438+0.8 billion yuan. The goal of the project is "integration, scale and modernization", which will realize the leap from traditional coal chemical industry in Jincheng to modern coal chemical industry. Jincheng, a "multi-carbon" city famous for its rich coal resources, is accelerating on the road of green economy and low-carbon economy. New energy development takes the lead in breaking through; Tourism development comes from behind; High-tech industries are ready to go. Wang Maoshe, Mayor of Jincheng, said that Jincheng has entered a critical period of accelerating transformation, striving for development and leaping development. We should take the development of emerging industries as an important measure to adjust the structure and cultivate new growth points, and build an emerging industrial system with Jincheng characteristics. We should persistently implement the strategy of establishing an ecological city, vigorously develop a green economy, strive to build a city brand of "Pearl of Taihang Mountain and Livable Jincheng", constantly improve the quality of life and happiness index of the people in the city, and make Jincheng a modern and livable new city that entrepreneurs yearn for, Jincheng people are proud of and outsiders envy. The coalbed methane reserves in Jincheng are 265,438+0.77%, which is the largest comprehensive coalbed methane field in China. But in the past, "sky lanterns" were everywhere here. Because coal mining must first extract coalbed methane, that is, gas, to reduce the concentration, it is really helpless to light the "sky lamp". How to "turn harm into benefit, save energy and reduce emissions, and improve the living environment"? Therefore, the Jincheng Municipal Party Committee and the Municipal Government issued the policy of "ensuring mining by pumping, promoting pumping by mining, ensuring pumping by pumping, and promoting pumping by using", and invested 672 million yuan to implement the comprehensive utilization project of coalbed methane in 2007. This move attracted companies such as PetroChina and CNOOC to join the mining industry. Up to now, 2730 coalbed methane extraction wells have been built here, with an annual extraction capacity of 2.3 billion cubic meters; 2/kloc-0 coalbed methane power stations have been built, with a total installed capacity of 1.8 million kilowatts. At present, coalbed methane is widely used by more than 50,000 households and all taxis in the urban area, and more than 3,000 coalbed methane vehicles have been rebuilt. There are more than 300 large-scale industrial and commercial users of pipeline coalbed methane in the city, and all the 28 coal-fired boilers in the urban area/KLOC-0 have switched to coalbed methane, with an annual consumption of more than 48 million cubic meters. This alone can reduce the use of coal by more than 200,000 tons, the emission of smoke and dust by more than 1000 tons and the emission of sulfur dioxide by more than 3,000 tons every year. Last year, the sales revenue of coalbed methane in Jincheng reached 2 billion yuan, realizing profits and taxes of 500 million yuan, driving the industrial added value to increase by 2.5-3 percentage points. It is estimated that the sales revenue will be 2 billion yuan this year and 5 billion yuan in 20 15. It is reported that the air pollution reduction project of Jincheng coalbed methane comprehensive utilization project, after winning the China Habitat Environment Model Award, is currently applying for the World Habitat Environment Model Award. Orchid Group, located in Jincheng, as a national flagship enterprise, has made continuous breakthroughs in the high-tech field in recent years. At present, nano, monocrystalline silicon, gas power generation and other new materials and new energy projects are becoming new economic growth points. In particular, the successful completion of the transformation project with an annual output of 40,000 tons of nano-calcium carbonate has made it a leader in the domestic industry, accounting for 80% of the national silica gel calcium market. Coal chemical industry is the pioneering field of Orchid Group in Shanxi. Orchid Clean Energy Company, jointly funded by Orchid Group and Hong Kong Huayang Group, has reached the annual production capacity of 200,000 tons of methanol and 654.38+10,000 tons of dimethyl ether. After the whole project is put into production, it will be one of the most advanced dimethyl ether production enterprises in the world. Last year, the output value of non-coal industry of Orchid Group surpassed that of coal industry for the first time, accounting for 50.4% of the annual output value. "From black to green, diversified development" is the main idea of Jincheng's transformation of development mode. A long history, culture and rich tourism resources are becoming another new force for Jincheng to break through. In recent years, the municipal government has frequently issued supporting policies to vigorously develop tourism. A group of coal enterprises have invested heavily in the development of scenic spots such as Imperial City Xiangfu, Wangmang Ridge, Manghe River and Jue Mountain. Now, Jincheng has built 4 1 large-scale tourist attractions, including 5 4A-level scenic spots, ranking second in the province. In 2009, it received 8.759 million tourists, up 65.438+02.74% year-on-year, and the city's tourism revenue reached 637./kloc-0.0 billion yuan, up 65.438+02.3% year-on-year. Develop continuous industries and extend the chain to the extreme; Develop new industries, and the products are close to high-end. Jincheng has vigorously developed high-tech industries and introduced a number of high-tech enterprises such as Foxconn, Park Chung-soo, Fuji, South Africa Hans and Xiangcheng Technology. Its high-tech products, such as optical communication connection module, high-power semiconductor light source series, foam ceramic filter series, gas explosion suppression equipment and digital refueling display, have filled the gaps in Shanxi Province. These enterprises have become the pioneers of new industries in this city. In addition, we will vigorously promote the refinement, standardization and scale of traditional industries, and enhance product grades and competitiveness. A batch of products are labeled as Jincheng Manufacturing. A number of middle and high-end products have entered the international market, realizing the transformation of the industry to diversification and middle and high-end direction. On June 25th, the Jincheng Municipal Government promulgated the Interim Measures for the Management of Support Funds for the Transformation of Economic Development Mode in Jincheng. It is proposed that efforts should be made to support and encourage the transformation of new technologies and new products into real productive forces, strive to improve the scientific and technological support level of the city's economic growth, cultivate and expand strategic emerging industries, and effectively promote the adjustment of the city's economic structure and the transformation of economic development mode. The focus of support is new expansion projects such as scientific and technological research and development, technology introduction, trial production of new products, technological transformation, energy conservation and emission reduction. .
