The project is scheduled to be ready for operation by November 30, 2020; by then, the solemn commitment to \"not discharge a single drop of production wastewater into the environment\" will be fulfilled, achieving true zero wastewater discharge. It is reported that Yulin Chemical’s “Demonstration Project for the Production of New Chemical Materials through the Differential Utilization of Coal” is currently the largest coal chemical project under construction in the world. The project covers an area of approximately 13 square kilometers, with an estimated total investment of 125 billion yuan. It represents the highest level of development in the coal chemical industry, featuring the greatest coal processing capacity, the highest degree of industrial integration, the most complex technology integration, and a supply chain that is closest to the end market. This project will have a profound impact on the further development of China’s coal chemical industry and will also determine the extent to which its supply chain can be expanded in the future. The project is constructed in two phases and four stages, comprising a total of 27 process units along with associated utility systems. These mainly include the medium- and low-temperature pyrolysis of 15 million tons of coal, the production of 5.6 million tons of methanol, 1.8 million tons of ethylene glycol, 2 million tons of MTO, as well as downstream products derived from these intermediates. The first phase of the project is scheduled to come online in June 2021, with the entire project to be completed and operational by the end of 2025. The investment for the first phase of this project is around 70 billion yuan, which will be used to build facilities capable of producing 1.8 million tons per year of ethylene glycol and 2 million tons per year of olefins, as well as a large number of fine chemical products derived from olefins. The facility for producing 1.8 million tons per year of ethylene glycol is part of the first stage of this project, and it represents the largest coal-based ethylene glycol production facility under construction worldwide. The estimated investment for this facility is 26.5 billion yuan.
