On September 10, the core equipment of Zotye Coal Coking’s 200,000 tons per year methanol hydrogen-carbon ratio optimization project – namely the regeneration tower and absorption tower – were lifted in accordance with the scheduled timeline. This marks the full entry of the project into the equipment installation phase, putting the overall construction on a fast track for progress and laying a solid foundation for the project’s commissioning on schedule. At the construction site, large-scale lifting machinery was operating noisily; the workers carried out technical briefings and safety checks in strict accordance with the specific lifting plan, while supervisors monitored the entire process on site. Thanks to the concerted efforts of everyone, the regeneration tower and absorption tower were lifted smoothly and installed in place with precision. The methanol hydrogen-carbon ratio optimization project is a key technical improvement initiative for the company this year. Focusing on the core stage of methanol synthesis, it employs innovative decarburization technologies to precisely adjust the hydrogen-carbon ratio of the syngas to the optimal value of 2.1. This approach improves the purity of methanol, meets the demands of high-end markets, and also extends the lifespan of catalysts, thereby achieving simultaneous improvements in economic efficiency and environmental sustainability. Since the project was launched, the company has worked closely with the construction contractor to overcome challenges such as tight deadlines and high technical requirements. It has developed a scientific construction schedule and strictly maintained control over safety, quality, and progress. Next, the company’s project management team will focus on key aspects such as the installation of process pipelines, insulation of the tower structure, and the installation and calibration of electrical instruments, to ensure that the project is completed and put into operation on schedule with high quality. Project Overview: Zhongtai Coal Coking is the first coal chemical enterprise in Baicheng County, Aksu Region, Xinjiang, to use coke oven gas for methanol production. The 200,000 tons per year methanol production facility based on coke oven gas is a supporting project for the 1.3 million tons per year coking plant and the 600,000 tons per year coking project. Through processes such as precise desulfurization, conversion, syngas compression, methanol synthesis, and methanol distillation, the remaining coke oven gas from coking is converted into methanol. Once the project is completed and put into operation, it will be able to consume 432 million cubic meters of excess gas from coke ovens each year, making effective use of 250 million cubic meters of hydrogen resources, thereby reducing carbon dioxide emissions by 39,500 tons. In addition, the project can produce 200,000 tons of refined methanol per year, generating an annual output value of 440 million yuan and profits and taxes of over 50 million yuan; it will also create more than 150 job opportunities in Baicheng County. Once the project is put into operation, it will further facilitate the transformation of local resource advantages, boost the economic development and structural adjustment of Baicheng County, and achieve simultaneous gains in terms of environmental protection and economic benefits. Zhongtai’s coal coking project with an annual capacity of 1.3 million tons is equipped with the first 6.25-meter ramming coke oven in Xinjiang region. It uses imported integrated ramming machines, and is accompanied by a coal preparation system, dry quenching facilities, coke treatment systems, gas purification facilities, as well as utility and auxiliary facilities. The investment in this project amounted to 1.695 billion yuan, and it began producing coke on June 1, 2019.
