On June 30, the circulating water systems of the third and fourth circulating water plants for this auxiliary project were successfully delivered, marking the entry of the project into its final phase. The circulating water plant is the project for which Sinochem Second Construction Branch has undertaken work under Shaanxi Coal Yulin Chemical – it features the largest contract value, was started earliest, has the longest construction period, and presents the greatest challenges. It utilizes the first set of water-saving mist-suppressing cooling towers in the country, along with new construction techniques. The 15 million tons per year demonstration project for the clean and efficient conversion of coal into various products, operated by Shaanxi Coal Group Yulin Chemical Co., Ltd., is located within the Qingshui Coal Chemistry Industrial Park in the Yulin-Yushen Industrial Park. The investment in this project amounts to 26.2 billion yuan, and it will be constructed in two phases and four stages. Phase 1 of the project is divided into two stages: Stage 1 involves the construction of an ethylene glycol plant with an annual production capacity of 1.8 million tons. The site area for this phase is approximately 4.4 million square meters, and the total investment required is around 26.5 billion yuan. It is currently the largest coal-based ethylene glycol production facility under construction in the world. In the second phase, projects for the production of 5.6 million tons per year of methanol, 2 million tons per year of olefins, and related downstream processing facilities will be constructed. Phase II of the project focuses on coal pyrolysis and is also divided into two stages. The first stage involves an industrial demonstration facility for the pyrolysis of 1.2 million tons per year of pulverized coal and the deep processing of 500,000 tons per year of coal tar. In the second stage, the scale of pyrolysis is increased to 15 million tons, and the coal tar industry chain is expanded to produce downstream products derived from aromatics and arylenes.
