From April 20 to 26, Tianchen Company conducted design reviews for the shift, low methane, synthesis, and tank farm units of the Baofeng coal-to-olefins project; at Tianchen Company, 3D model review meetings were held for 90% of the shift unit, 60% of the low methane unit, 60% of the synthesis unit, and 60% of the tank farm. Relevant personnel from Ningxia Baofeng Energy Group Co., Ltd. and the project department of Tianchen Company attended this review meeting. At the meeting, the Baofeng Energy project team provided valuable suggestions regarding the current design work, while the designers from Tianchen Company gave a detailed explanation of the project design. Through in-depth discussions, the participants from both sides reached consensus on optimizing various design details. In addition, the Baofeng Energy project team, drawing on the practical production experience of Baofeng’s existing plant and taking cost and efficiency factors into full consideration, put forward optimization suggestions in various aspects such as the detailed design PID, equipment drawings, pipeline layout of the installation, construction feasibility, operational simplicity in production, and convenience for inspection and maintenance. Both teams agreed that the current design work complies with the requirements of specifications such as the \"Regulations on the Design Content for Foundations of Petrochemical Plants,\" and fully meets the deadlines for the review of the 3D models. The 3D model of this project has successfully passed the progress review, marking an important milestone in the project and bringing the design work to a new stage. The successful completion of the model review laid a solid foundation for the project to fully shift to construction and installation. In December 2019, the third phase of Ningxia Baofeng Energy’s 500,000-ton coal-to-olefins project was launched. The project will construct a 1.5 million tons per year coal gasification to methanol plant (4 in operation and 2 as backups), a 500,000 tons per year methanol to olefins plant, a 250,000 tons per year ethylene-vinyl acetate copolymer (EVA) plant, a 300,000 tons per year polypropylene plant, along with the necessary utility systems and auxiliary facilities. Upon completion and reaching full production capacity, the project will primarily have an annual production capacity of 250,000 tons of EVA, or a partial production capacity for low-density polyethylene; 300,000 tons of polypropylene; as well as by-products such as propane, C4, C5, and sulfur. The coal required for the project is obtained by the project owner through market-based procurement. The project is located in Area A of the Linhe Comprehensive Project Zone in the Ningdong Energy and Chemical Industry Base. The total investment for the project is 1,377,000 million yuan, of which 1,298,201 million yuan is allocated to construction costs, 9,991 million yuan to working capital for the initial phase, and 68,808 million yuan to interest during the construction period. The funding comes from the enterprise’s own funds in the amount of 413.1 million yuan, accounting for 30% of the total investment, with the remaining amount being covered through bank loans and other sources. The project builds on the enterprise’s existing engineering expertise in gasification processes; it utilizes Beijing Aerospace’s pressurized coal gasification technology, Linde’s technology for low-temperature methanol washing, and the first-generation technology developed by the Dalian Institute of Chemical Physics under the Chinese Academy of Sciences (with a capacity of 500,000 tons per year per system) ； Olefin separation utilizes technology from the American company KBR ； The polypropylene PP plant uses the Lyondellbasell gas-phase process, while the EVA plant employs the Basel high-pressure tubular process ； Sulfur recovery employs a process that includes high-temperature Claus in the furnace, two-stage low-temperature catalytic Claus, hydrogen reduction, and selective oxidation; after combustion of the exhaust gases, they are sent to the power island in the Linhe Industrial Park (where they enter two desulfurization systems in the power station).
