On July 24, the 1.8 million tons/year ethylene glycol project of Yulin Chemical Coal Quality Utilization and New Chemical Materials Demonstration Project of Shaanxi Coal Group was inaugurated in Yulin Qingshui Industrial Park, marking that the largest coal chemical project under construction in the world has entered the construction stage from the design stage. Guo Peicai, member of the Standing Committee of the Yulin Municipal Committee and head of the United Front Department, attended the ceremony and announced the start of construction. Cui Ling, Deputy Secretary-General of Yulin City, Yushen Industrial Zone Management Committee and responsible persons of relevant units participated.

It covers an area of about 13 square kilometers. There are 27 sets of process units and supporting public utilities, including 15 million tons of coal pyrolysis at medium and low temperature, 5.6 million tons of methanol, 1.8 million tons of ethylene glycol and 2 million tons of poly. Esters, 2 million tons of olefins and downstream products using them as intermediate raw materials have converted more than 20 million tons of coal annually, with an estimated total investment of more than 120 billion yuan.
The project is divided into two phases and four phases. The investment of the first phase is about 70 billion yuan. The 1.8 million tons/year ethylene glycol is the first phase of the project. It is also the largest coal-based ethylene glycol plant in the world. It is planned to produce qualified products in June 2021. The whole project is expected to be completed and put into operation in 2025.
