The 100,000-ton new material project of Panjin Sanli Zhongke uses the three-step process for MMA developed by the Dalian Institute of Chemical Physics
Thread Content
The Panjin Sanli MMA project is set to begin trial production. On November 14th, according to a report from Panjin Publishing, the construction of the main facilities for Panjin Sanli Zhongke New Materials Co., Ltd.’s plant with an annual production capacity of 100,000 tons of new materials has been completed. Comprehensive finalization work is currently in progress, and the plant is about to enter the stage of equipment testing and trial production. Its core technology, the three-step process for producing MMA from ethylene, was developed by the Dalian Institute of Chemical Physics, Chinese Academy of Sciences; it is the first of its kind in China and ranks at the international leading level. MMA is an important chemical raw material that is widely used in high-tech fields such as aerospace, medicine, and optics, offering broad market prospects. According to the company’s management, the successful transition of these new achievements from the laboratory to the production line is made possible by the comprehensive support provided by the Panjin Fine Chemicals Pilot Plant in Liaoning – including facilities, warehouses, as well as talent and technology – thereby enabling a breakthrough similar to that achieved with \"Darwin’s Dead Sea\". It is understood that the project commenced construction in January 2022 in the western expansion area of the Panjin Fine Chemicals Industrial Development Zone. The total investment in the project amounts to 2.1 billion yuan, of which 1.1 billion yuan is allocated to the first phase. The project covers an area of 269 mu and is designed to produce 50,000 tons of MMA/PMMA as well as 50,000 tons of n-propanol per year. Project changes: On May 13 of this year, Panjin Sanli Zhongke New Materials Co., Ltd. published a pre-submission announcement for the environmental impact assessment report related to its project aimed at producing 100,000 tons of new materials per year. The environmental impact assessment involved adjustments to the original project plan; below are some of the key details: Construction content and scale: The project will include a gas generation unit with a capacity of 12,000 Nm3/h (comprising both the gas generation unit itself and a syngas purification unit with the same capacity), an MMA production facility with an annual capacity of 50,000 tons (including a formaldehyde production unit with a capacity of 50,000 tons and an MMA production unit with the same capacity), and a n-propanol production facility with an annual capacity of 40,000 tons (including a propionaldehyde production unit with a capacity of 80,000 tons and a n-propanol production unit with a capacity of 40,000 tons). Reason for project change: After the original environmental impact assessment was approved, Sanli Company adjusted the project’s production plan based on the market conditions for raw materials and products, deciding to retain only 3 out of the 5 production units. These units include the gas generation unit, the MMA production unit, and the propanol production unit. The capacity of the gas generation unit and the MMA production unit remained unchanged, while the capacity of the propanol production unit increased from 30,000 tons per year to 40,000 tons per year. In addition to the facilities under construction, the storage and transportation system of this project includes 19 additional storage tanks, bringing the total tank capacity to 5000 m3.
In April 2024, the development project for producing methyl methacrylate via ethylene carbonylation at Yan’an Energy Chemicals (the MMA pilot plant) was completed 5 days ahead of schedule, successfully meeting the set objectives. The construction quality and safety management of the project received high praise from Yan’an Energy Chemicals. It is reported that this project is an important measure to promote the transformation of Yanchang Petroleum products toward higher-end qualities and diversification; it represents an industrial pilot-scale testing facility for the technology of producing methyl methacrylate through the esterification of ethylene carbonyl, developed through collaboration between CNOOC’s research team and Yanchang Petroleum. Through on-site pilot tests, the technology for producing methyl methacrylate via ethylene carbonylation esterification has been made available domestically, providing technical support for the value-added utilization of low-carbon olefin resources in petroleum refining and chemical industry as well as coal chemical enterprises.
On November 15, 2022, the review of the 60% scale model for the Panjin Sanli new material project with an annual production capacity of 100,000 tons, which was overall contracted by Huisheng Engineering, was successfully held at the Huisheng Center. The review includes a 60% model review of all units in the plant, as well as PID reviews for multiple units such as gas generation, formaldehyde, n-propionaldehyde, n-propanol, MMA, and air separation, along with the plant’s utility systems, pipeline systems, and tank farms. This project features technical cooperation with the Institute of Catalysis, Chinese Academy of Sciences; the process package was jointly developed by Huisheng Engineering and the project owner Sanli, representing advanced technology in China. By combining three processes – \"ethylene hydroformylation to produce propionaldehyde\", \"aldol condensation of propionaldehyde and formaldehyde to produce acrolein\", and \"one-step oxidative esterification of acrolein to produce MMA\" – a new three-step process for synthesizing MMA from ethylene is achieved. This approach offers advantages such as a short reaction sequence, mild reaction conditions, no emission of toxic substances, as well as high conversion rates and selectivity. It opens up new avenues for MMA synthesis and holds good prospects for application. The project investor is Panjin Sanli Zhongke New Materials Co., Ltd., with an investment plan of 2.1 billion yuan; the construction of the factory is expected to begin within this year. The main construction components of the project include 5 production unit areas, 1 sewage treatment plant, and supporting facilities such as 1 production auxiliary building; once completed, it will be able to produce 100,000 tons of new materials per year.
