Clicks: 18. According to Huating Coal Industry, as of March 24, 2023, Qingneng Coal Chemical Industry produced 145,300 tons of refined methanol and sold 143,000 tons of it, generating revenue of 309 million yuan and thus achieving a successful start to the first quarter. The optimization work for the polypropylene plant is progressing steadily. Focusing on the goal of commissioning the polypropylene plant, we adhere to a two-step commissioning strategy and take multiple measures to accelerate the process of optimizing the plant. At the beginning of February, a special meeting was held in coordination with the constructor, Tianchen Company, to address matters such as the system optimization of the polypropylene plant and the rectification of issues related to commissioning, and specific measures were agreed upon. In line with the company’s overall requirements of “six unwavering principles,” on February 23, technical discussions were held with the sales department of Sinopec Catalyst Co., Ltd. regarding high-value-added polypropylene products, in order to advance the achievement of the goal of extending and strengthening the coal chemical industry chain. To date, 70% of the total work required for the renovation of the internal components in the regenerator of the reaction regeneration unit has been completed, while 40% of the work related to the modification and removal of the CO auxiliary combustion system has been finished. Other projects are progressing steadily according to the planned schedule, laying a solid foundation for starting trial production by the end of June. The 200,000-ton polypropylene production facility of Huating Coal Industry Group utilizes the FMTP technology jointly developed by Sinochem, Tsinghua University, and Huahua Group, as well as catalysts independently developed by Tianchen Company; it is China’s first fluidized-bed methanol-to-propylene plant. Commissioning began at the end of 2021.
