On July 2, the 35KV substation for coking in this project was successfully connected to the power grid for the first time. The 35KV substation is one of the key projects of this initiative. Throughout the construction process, all tasks progressed smoothly; civil engineering work, line installation, electrical installations, and all other related tasks were subject to three levels of inspection, with a 100% pass rate. During the preliminary acceptance, final acceptance, and power-on acceptance, the project team addressed all identified issues in a high-quality and efficient manner, ensuring power supply as quickly as possible, which provided strong support for the smooth progress of subsequent stages. The successful power delivery marks a further solid step forward in the project’s development. It is reported that the project is located within the existing facility of Hohhot Xuyang Zhongran Energy Co., Ltd. in the coal chemical industry zone of the Qingshuihe County Industrial Park in Hohhot, covering a total area of 695,000 m2. The project plans to construct a coking plant with an annual capacity of 3.6 million tons. The coking process will utilize 4×65-hole, 6.78-meter-high single-hearth ramming coke ovens. The main construction elements include the coking plant, a synthetic ammonia plant with an annual capacity of 450,000 tons, and a PSA hydrogen production facility. Additional facilities include 2×260-ton-per-hour dry quenching units, systems for desulfurization and denitrification of flue gas from the coke ovens, gas purification units, storage areas for raw materials and products, coal receiving pits, and coke storage buildings – all of which are part of the utility and auxiliary infrastructure. The production capacity of the project is 3.6 million tons of dry quench coke and 450,000 tons of liquid ammonia per year. The by-products include 1.7 billion cubic meters of coke oven gas, 850 million cubic meters of hydrogen, 160,000 tons of coal tar, 50,000 tons of crude benzene, and 60,000 tons of ammonium sulfate. The total investment for the project is 4.8 billion yuan, of which 269.76 million yuan is allocated to environmental protection measures, accounting for 5.62% of the total investment.
