On the afternoon of January 10, the first MN regeneration tower for this project, part of Shaanxi Coal Group Yulin Chemical’s demonstration project aimed at producing new chemical materials through the optimized use of coal, was successfully installed. This marked a successful start to the installation of large-scale equipment in 2021. The MN regeneration towers are the largest and heaviest equipment in the dimethyl oxalate synthesis plant, with a total of 6 units. The lifting equipment used this time is 110742-T-302. The bare tower weighs 276.65 tons, is 42.778 meters tall, with a diameter of 6.2 meters at the top and 8.8 meters at the bottom; after being fitted with its accessories, the total weight of the tower is 346 tons. Lifting was carried out using 2,200-ton and 400-ton crawler cranes in combination, and it was successfully placed between the two composite frames in just two hours. The \"Demonstration Project on the Utilization of Coal at Different Grades to Produce New Chemical Materials\" carried out by Yulin Chemical of Shaanxi Coal Group is currently the largest coal chemical project under construction in the world. The total investment in this project amounts to 126.2 billion yuan, and it enables the conversion of over 24 million tons of coal per year. It produces a variety of products, including polyolefins, polyesters, polycarbonates, polystyrene, and acrylates, primarily through the systematic integration of a range of advanced processing technologies such as coal pyrolysis and gasification. The currently under construction Phase 1, Stage 1 project for an annual production capacity of 1.8 million tons of ethylene glycol requires an investment of around 26.5 billion yuan. Three design institutes and engineering companies from Sinochem, along with 10 construction firms, are involved in this project, with a cumulative contract value exceeding 10 billion yuan. Among them, the first phase of Project Phase 1, which involves an ethylene glycol production capacity of 1.8 million tons per year, covers an area of approximately 4.4 million square meters. The total investment required for this project is estimated at around 26.5 billion yuan. It is currently the largest coal-based ethylene glycol production facility under construction in the world, with completion scheduled for June 2021 ； Phase 1, stage 2 involves the construction of a facility capable of producing 5.6 million tons per year of methanol and 2 million tons per year of olefins, along with related processing units; completion is scheduled by the end of 2023. 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 1.2 million tons per year of pulverized coal pyrolysis and 500,000 tons per year of advanced processing of coal tar; completion of the construction is scheduled for June 2021 ； In the second phase, the scale of pyrolysis will be increased to 15 million tons, and the coal tar industry chain will be expanded to produce aromatics as well as downstream products derived from arylene compounds. Construction is scheduled to begin in 2022, with all construction work to be completed by the end of 2025.
