Zhongtai Coal Coking’s 200,000-ton/year methanol production facility from coke oven gas successfully produced qualified methanol products. Author/Source: Gasification World. Date: January 21, 2021. Clicks: 10. On January 20, good news came from Zhongtai Coal Coking’s project for producing methanol from coke oven gas at a capacity of 200,000 tons per year – the distillation process was successfully tested, and qualified methanol products were produced at 10 a.m. on that day. Since the end of December, in line with the progress of on-site commissioning, the company has completed the \"three inspections and four determinations\" for the synthesis and distillation processes of the methanol plant, pipeline steam purging, individual and combined compressor tests, as well as catalyst loading. To prevent blockages and freezing in the unit during the water-cooled commissioning of the distillation unit, the methanol project assigned specialized technical personnel to conduct thorough inspections and develop detailed plans, adopting a commissioning method that utilizes methanol in the cooling process based on the specific conditions. Ultimately, the material trial run of the distillation unit in the methanol project was successful on the first attempt. Tests have shown that all parameters and indicators of the produced methanol meet the top-grade standards set by national regulations. The successful commissioning of the distillation unit has laid the foundation for the subsequent joint testing of the methanol project. It is understood that Zhongtai Coal Coking is the first coal chemical enterprise in Baicheng County, Aksu Region, Xinjiang, to use coke oven gas for methanol production. The company’s 200,000 tons per year methanol production facility generates methanol through processes such as precise desulfurization, conversion, syngas compression, methanol synthesis, and methanol distillation. This approach features low investment costs, high output, energy efficiency, and good economic benefits. 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, and make use of 250 million cubic meters of hydrogen resources. This will result in a reduction of 39,500 tons of carbon dioxide emissions, thereby addressing the environmental pollution caused by the release of coke oven gas. 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.
