At 11:10 on September 5, 2020, the circulating hydrogen buffer tank (V-104) for the hydrogen supply solvent and light oil combined hydrogenation unit in the aforementioned EPC project was successfully installed, with Shengbang Technology Co., Ltd. being the contractor for this task. With a net weight of 40.402 tons and a height of 10.650 meters, this equipment marks the official start of the installation work for the pyrolysis startup project. This is another important milestone in the construction of the pyrolysis project, following the civil engineering work. It is expected that 15 units of equipment will arrive in September. The pyrolysis project team will organize the work carefully in accordance with the order of arrival of the equipment, to ensure its proper installation and lay a solid foundation for subsequent pipeline installation. Yulin Chemical is carrying out the construction of a demonstration project for the production of new chemical materials through the differentiated utilization of coal in the Qingshui Industrial Park of the Yushen Industrial Zone. As the largest coal chemical project under construction globally at present, this project covers an area of approximately 13 square kilometers. The total investment planned is 126.2 billion yuan, and it will be able to process more than 24 million tons of coal per year. 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 requires an investment of around 70 billion yuan; it will involve the construction of facilities for producing 1.8 million tons per year of ethylene glycol, 5.6 million tons per year of methanol, and 2 million tons per year of olefins, as well as a large amount of fine chemical products derived from these olefins. The 1.8 million tons per year ethylene glycol production facility is part of the first phase of this project; it is also the largest coal-based ethylene glycol production plant under construction worldwide. The estimated investment for this facility is 26.5 billion yuan. The project utilizes Collin’s patented dry powder gasification technology and Japan’s patented technology for producing ethylene glycol from syngas. Shanxi Coal Group Yulin Chemical Co., Ltd. and Nippon Kako Kagaku Co., Ltd. jointly invested in establishing Shanxi Coal Group Yulin Chemical Yugao Chemical Co., Ltd. to build and operate facilities for the production of oxalate esters as well as for the hydrogenation of oxalate esters to produce ethylene glycol. One of the overall goals set for the project construction is that by June 30, 2021, both the first phase of Project Phase I, which involves an ethylene glycol production facility with a capacity of 1.8 million tons per year, and the first phase of Project Phase II, which includes a coal pyrolysis facility with a capacity of 1.2 million tons per year along with a pilot plant for the deep processing of coal tar with a capacity of 500,000 tons per year, should reach mechanical completion – this goal is referred to as “21630”.
