On July 5, the signing ceremony for Shanxi Coking Group’s project to produce 5 million tons of coke annually and to make advanced use of coke oven gas was held in the lecture hall on the first floor of the comprehensive office building in Jinzhong City. Zhao Jianping, Secretary of the Jinzhong Municipal Party Committee, Wang Maosheng, Secretary of the Party Committee and Chairman of Shanxi Coking Coal Group, and other leaders were present to witness the signing. The successful signing of this project marks its official implementation in the Jiexiu Economic and Technological Development Zone. It is understood that the total investment in this project is 8 billion yuan, with a planned land area of 2,000 mu. It is funded and constructed by Shanxi Coking Group, with private enterprises also involved in its development. By making use of the coking production capacity of both Shanxi Coking Group and these private enterprises, the existing land is put to better use, and the projects are developed through joint investment. This represents a collaboration between state-owned and private enterprises, and it serves as a model for private enterprises to participate in the reform of state-owned enterprises and thereby drive corporate transformation. The project adopts a unified planning and phased construction approach. For the first phase, an investment of 2.7 billion yuan is allocated to build 2 large-volume single-heating top-loading coke ovens with 70 chambers each, having a carbonization chamber height of 7.65 meters, and an annual production capacity of 2 million tons. Supporting production facilities include those for coal preparation, coking processing, dry quenching of coke, gas purification, desulfurization and denitrification of coke oven flue gas, biological and advanced treatment of coking wastewater, as well as an integrated utility tunnel connecting to the methanol project. After the project is completed, the coke oven gas generated will be used not only for the existing Yida methanol production but also to build a project capable of producing 60,000 tons of liquid ammonia per year, by utilizing the off-gases produced in the methanol manufacturing process. In addition, facilities for hydrogen separation, collection, storage, and transportation have been planned to lay the foundation for the further development of the hydrogen energy industry. The second-phase project involves an investment of 3.3 billion yuan to build coke ovens with a production capacity of 2 million tons per year and a carbonization chamber height of 7.65 meters, equipped with top-loading systems. Once phases one and two are completed, a project to produce 180,000 tons of LNG per year will be established using the coke oven gas; this will not only supply carbon for Yida Methanol but also increase the liquid ammonia production to 75,000 tons per year. Additionally, a project to convert LNG into acetylene or ethylene will also be planned. Phase three of the project involves an investment of 1.5 billion yuan to build a ramming coke oven with an annual production capacity of 1 million tons and a carbonization chamber height of 6.25 meters. The coke oven gas generated is used to extract methane for the production of LNG, while the remaining hydrogen is utilized to manufacture hydrogen-rich fuel products. Taking advantage of hydrogen’s properties such as being non-toxic and harmless, having good thermal conductivity, a high ignition point, and a fast combustion rate, it is widely used in power generation, as a fuel for engines, and in fuel cells. The equipment used in this project incorporates China’s most advanced coke oven technology, offering advantages such as high coke production volume, reduced land usage, good economic efficiency, high degree of automation, and energy conservation. It also features advanced technologies such as multi-stage heating, automatic temperature monitoring, and furnace temperature control, which enable automatic heating and control of the coke ovens. This ensures that no dust is released during coal loading and coke extraction, thereby maximizing economic benefits while safeguarding the environment. Upon completion of the entire project, it is expected to generate annual sales revenue of 12 billion yuan and create profits and taxes of over 1.5 billion yuan. It will also provide numerous employment opportunities for local villagers, improve the efficiency of coal resource utilization, enable the maximum exploitation of clean energy, and thus achieve both social and economic benefits. The implementation of this project will build on the advantages of Shanxi Coking Group’s coal and coking industry, extend the industrial chain, and enable higher-value utilization of coal and coke. It complies with **industrial policies and environmental regulations, offers a strong demonstration effect, and has promising market prospects. It will also provide strong impetus for the upgrading and green development of the coking industry in Jiexiu City, help to establish a provincial-level coking industry cluster with an annual production capacity of tens of millions of tons, and enable the city to take the lead in the energy revolution across the province.
