Progress on the Construction of the Methanol Production Project Using Coke Oven Gas in Xinjiang by Henan Nenghua Author/Source: Huahua Net Coal Chemicals Date: 2020-09-02 Clicks: 10 On August 29, the turbine, air compressors and other air separation equipment for Henan Nenghua Xinjiang Company’s 200,000 tons per year methanol production project using coke oven gas were successfully installed, laying the foundation for the subsequent installation of the air compressor units. Turbines and air compressors are the core equipment of the air separation unit in methanol projects, and their installation progress directly affects the overall commissioning schedule of the project. Upon the arrival of the equipment at the site, the company promptly contacted the manufacturer, the general contractor, the supervisor, and the construction unit to jointly carry out an unpacking inspection of the equipment, ensuring that its casing was undamaged, that all accessories were present, and that the overall surface of the equipment had no scratches or damage. At the same time, an inspection of the construction lifting site is carried out to determine the lifting plan, and safety and technical instructions are provided to the personnel involved in the lifting operations to ensure construction safety. During the lifting process, various teams worked together to address practical challenges such as the turbine’s heavy weight, complex structure, and limited installation space. Two 50-ton cranes were used in conjunction to successfully complete the lifting of both the turbine and the air compressor. 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 supplementary project to 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. 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 processing 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.
