Progress in the Construction of the Chemical Gasification Unit in Yulin Author/Source: Coal Chemical Engineering 114 Forum Date: 2020-08-24 Clicks: 10 On August 4, the Chemical Gasification and Purification Project Team in Yulin, in collaboration with Tianchen Company, launched a labor competition at the project site aimed at accelerating progress and meeting deadlines, with the goal of working hard for 80 days – thus marking the beginning of the effort to speed up the project’s progress. The activities will be fully launched on August 4th and will conclude on October 24th. To ensure the smooth progress of this initiative, the project department established a leadership team for the “80-Day Intensive Effort” campaign, assigned specific individuals to handle each task, and put in place regular meeting and supervision systems to promptly coordinate and resolve any related issues ； A launch conference was held to align thoughts and strengthen confidence ； At the same time, by sorting out construction tasks and monitoring project progress, milestone tasks are identified, construction is carefully organized, and every effort is made to ensure that the scheduled deadlines during the event period are met successfully. Since the project started on April 1, the project team has made progress the top priority, ensuring site safety and project quality. In the construction of the coal gasification unit, they have worked together with Tianchen Company to continuously optimize the construction plans, refine the goals and tasks, and ensure that there are sufficient personnel, machinery, equipment, and materials on site in order to accelerate the construction pace. All milestones of the pulverized coal gasification unit have been completed ahead of schedule, achieving a phased victory. Recently, the construction site of this project has been at the forefront, going all out to advance the goal of \"21630\". The \"Demonstration Project for the Production of New Chemical Materials through the Differential Utilization of Coal\" carried out by Yulin Chemical of Shaanxi Coal Group 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. As a coal conversion demonstration project with the highest coal processing capacity, the greatest degree of industrial integration, the most complex technology integration, and a supply chain that is closest to the end market, this project represents, to a certain extent, the highest level of development in the coal chemical industry. It will have a profound impact on the further development and direction of China’s coal chemical industry, as well as determine the extent to which China’s coal chemical supply chain will be able to expand 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 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 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, while also manufacturing 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 globally. 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.
