From September 18 to 23, a review meeting for the 30% scale model of the DMTA unit in Shaanxi Yueneng Fine Chemicals Company’s 1 million tons per year high-end chemical materials project was held at Sinopec Guangzhou Engineering Company. Based on the PID process flow diagram and the 30% 3D model, this review focuses on the core design aspects of the DMTA unit, including the rationality of the layout of major equipment, the compliance of the routes of important pipelines, as well as the feasibility and safety of operation and maintenance. During the meeting, the design team presented a comprehensive report on the design scheme, while the participants offered a number of constructive optimization suggestions based on their production experience and project insights, laying a solid foundation for further refining the model and ensuring the high-quality development of the project. As the key unit of the entire plant, the successful completion of the 30% scale model review for the DMTA unit marks an important milestone in the project’s development. Next, the company will work closely with the Guangzhou Institute, adhering to scientific, safe, and practical design principles to advance subsequent tasks efficiently, thereby improving the quality of the project and its inherent safety levels and ensuring its steady progress. Shaanxi Yueneng Fine Chemical Materials Co., Ltd.’s 1 million tons per year production facility for high-end chemical materials is located in the South Area of the Qingshui Industrial Zone within the Yushen Industrial Park in Yulin City. It covers an area of 1,500 mu, with a total planned investment of 10.3 billion yuan. The project is aligned with the \"dual carbon\" goals; the industry is moving toward greener practices, featuring high revenues and low energy consumption. After accounting for the energy used in raw materials, the annual comprehensive energy consumption equals 269,000 tons of standard coal. There are nearly 10 categories of products, all of which target the end-market directly. Construction on the site preparation for the project began in February 2024, with completion scheduled for October 2026. The construction scope mainly includes a 400,000-ton/year DMTA plant, a 200,000-ton/year ethylene oxide plant, a 200,000-ton/year polyether superplasticizer monomer plant, a 100,000-ton/year propylene oxide plant, a 260,000-ton/year hydrogen peroxide plant, an 80,000-ton/year acrylic acid plant, a 120,000-ton/year butyl acrylate plant, a 400,000-ton/year acrylate emulsion plant, a 400,000-ton/year polycarboxylate superplasticizer plant, as well as supporting auxiliary facilities.
