"As a national demonstration base for the new industrialized aluminum industry, an important energy and chemical base in Shanxi Province, and one of the six ten-million-ton coking bases in the province, Hejin City is transforming from a'coking' to'fine chemical', and strives to promote coal, electricity and aluminum. The integrated development of materials is committed to building a national new aluminum-magnesium alloy industrial base and a fine chemical industrial base." From July 26 to 28, 2018, the China trip to investigate the sustainable development of petroleum and chemical parks organized by China chemical industry newspaper entered Hejin. The introduction of Ju Zhen, member of the Standing Committee of Yuncheng municipal Party committee and Secretary of Hejin municipal Party committee, impressed the research group.

Abundant resources in the three gardens of the first district

It is understood that the Hejin Economic and Technological Development Zone covers an area of 24 square kilometers and has developed into a development that covers a new type of coal, electricity and aluminum integrated industrial park, a new type of coal coke toughened recycling industrial park, and a strategic emerging industrial park. pattern. At present, there are 43 enterprises, including 29 enterprises above designated size. The raw coal reserves in the territory are 0.68 billion tons, which is the zui good export of raw coal mining in Hedong Coalfield. Limestone, pyrite and other mineral reserves are abundant. The two gas supply pipelines of National New Energy and National Energy Natural Gas cover the whole territory, with a daily supply capacity of 300000 cubic meters of natural gas and 2.4 million cubic meters of coke oven gas. The Yellow River flows 30 kilometers through the territory, and the daily water supply capacity of the completed water lifting project is 900000 cubic meters, providing sufficient water source guarantee for industrial development. The total installed capacity of the motor is 1.8 million kilowatts, providing a reliable energy supply for industrial development.

Zhao Jianxi, mayor of Hejin City, told the research team that Hejin City currently has a total coke production capacity of 10.7 million tons, accounting for 7% of the province's total. It supplies more than 2 billion cubic meters of gas annually and produces 1 million tons of coal tar, carbon black, asphalt, industrial naphthalene and other chemical products annually. It has formed a new industrial pattern with three major industries of coal coking, coal electricity, aluminum and steel casting as its pillars and photovoltaic solar energy, precision casting, modern medicine, fine chemical industry, and building materials. With an annual output of 15 million tons of raw coal, 10 million tons of coke, 4.5 million tons of iron and steel, 2.6 million tons of alumina and 500000 tons of electrolytic aluminum, it is one of the national new industrialized aluminum industry demonstration base, an important energy and chemical base in Shanxi Province and one of the six 10 million ton coking bases in the province. Hejin City is building a national new aluminum-magnesium alloy industrial base and fine chemical industry base.

Coking and fine development

According to he Honglin, vice mayor of Hejin City, Hejin is an important coal coke industry base in Shanxi Province. According to the idea of "black coal, green mining, coal coke processing and circular development", relying on enterprises such as China Coal Huajin Wangjialing and sunshine group, Hejin vigorously develops coalbed methane and coal tar deep processing, and accelerates the transformation from "simultaneous coking" to "fine chemical industry.

"There are 10 coking enterprises in Hejin, namely Sunshine Coking, Sunshine Huatai, Xinsheng Coking, Shuguang Coal Coking, Huasheng Energy, Yongxin Group, Longmen Technology, Kangzhuang Coking, Jinxin Coking and Zhongyang Energy. Carbon black enterprises 4, respectively, Jinlong carbon black, Longmen carbon black, black horse carbon black, Anlun chemical. Tar deep processing to Sunshine Group-based, and another Shengtian fine chemical (crude phenol deep processing) and under construction of Xinhaixiang new materials (deep processing of oil) 2 small and micro enterprises. While stabilizing coke production, Hejin has vigorously developed the deep processing of coking products. At present, the comprehensive utilization of coke oven gas, coal tar processing and the primary processing capacity of the two major industrial chains have formed a scale. The deep processing is dominated by Sunshine Group. High-end products such as naphthalene series, benzene series, mesophase carbon microspheres and microfiber glass wool have emerged. The proportion of coking enterprises' income has been continuously increasing." Hejin City Wangjialing Circular Economy Industrial Park Management Committee Director Zhang Kuifeng said.

Zhou Yan, executive deputy general manager of Shanxi Sunshine Coking Group and Shanxi Haolunke Chemical Co., Ltd., who accompanied the investigation, told the research team that Sunshine Coking Group is the "flagship enterprise" of the national independent coking industry, the "top five enterprises" of the carbon black industry, and the "rising star" of fine chemicals and carbon materials industry ". It is the main carrier of Hejin base of six "10 million ton coking production bases" in Shanxi Province and the leading enterprise in Hejin Economic and Technological Development Zone. At present, it has formed a clean and environment-friendly advanced coal coke chemical and new material enterprise group integrating "coal mining, raw coal washing, coke smelting, tar processing, fine chemical industry, new carbon materials, self-provided power plants, railway line delivery, logistics and trade, and international trade.

Talking about the topic of how to change from "simultaneous development of coking" to "fine chemical industry", Han Ximin, chief engineer of Shanxi Haolunke Chemical Co., Ltd., said that currently Sunshine Group Haolunke and Tianjin University School of Chemical Engineering have signed a number of cooperation agreements such as "Shanxi Sunshine Coking Group Coal Tar Deep Processing Industry Planning", "Naphthalene Sulfonic Acid Neutralization and Continuous Technology Development and Alkali Fusion Reaction Mechanism Test", "and Joint Construction Laboratory Building, carry out in-depth cooperation to lay the foundation for the development of fine chemical industry.

Coal and electricity aluminum has become dominant

He Honglin told the research team that Hejin is an important aluminum processing base in China, relying on Chinalco Shanxi New Materials Co., Ltd., with the goal of building a national aluminum-magnesium alloy base and a 100 billion industrial cluster, focusing on the two paths of deep processing of alumina and electrolytic aluminum, and accelerating the integrated development of coal, electricity and aluminum. In terms of scientific and technological innovation, professional research laboratories have been set up to focus on leading industries, and research and development institutions such as Chinalco New Materials, Jinhua Huixing, Anlun Chemical, Jinaluminum Refractive Materials, and Jinjin Chemical have been established to provide technical support for industrial transformation and upgrading.

Shi Yujiang, head of the Hejin Economic and technological Development Zone, said that the integrated industry of coal, electricity and aluminum is a major leading industry in the development zone. At present, Chinalco's "1 3" high-precision aluminum strip project with an investment of 1.68 billion yuan is ready to settle in Hejin Development Zone. Chinalco Shanxi New Materials Co., Ltd. is the first large-scale enterprise in Shanxi Province to have a complete aluminum industry chain with "mine-alumina-electrolytic aluminum-aluminum processing" and supporting self-provided generator sets. It is the first "double tens of billions" aluminum industrial enterprise with assets of tens of billions and annual output value of tens of billions. By the end of 2017, Chinalco Shanxi New Materials Co., Ltd. has an asset of 12.9 billion billion yuan, with an annual output of 2.5 million tons of alumina, 420000 tons of electrolytic aluminum, 150000 tons of aluminum alloy and 210000 tons of anode carbon.

Of course, Hejin has also encountered difficulties in promoting the integrated development of coal, electricity and aluminum. Shi Yujiang told the research team that a major bottleneck encountered in the landing of the project and supporting the aluminum deep processing project was that although Hejin had coal, the self-supply rate of electricity was low, most of the power generation was integrated into the large grid, and the price of electricity had no advantage. "Enterprises in the development zone, especially electrolytic aluminum and aluminum processing enterprises, are separated from power plants by a wall, but they cannot enjoy self-provided electricity prices, which makes our resource advantages in Hejin unable to be used, resulting in difficulties in the electrolytic aluminum industry and difficulties in the development of aluminum processing enterprises. It affects the development of coal, electricity and aluminum integrated industrial clusters, and we expect the media to call for this." Shi Yujiang said.
