Review of 30% scale models for the ethylene oxide unit and the polyether superplasticizer monomer unit in Shaanxi Yueneng’s 1000,000 tons/year high-end chemicals and new materials project: From March 24 to March 27, a review meeting for the 30% scale models of these two units was held at Xi’an Hualu Company by Shaanxi Yueneng Fine Chemicals Materials Co., Ltd. The meeting was held in a hybrid online-and-offline format, with specially invited technical personnel from patent holders and industry experts in attendance, as well as relevant staff from the Production Technology Department. It is reported that this review will conduct a comprehensive examination of aspects such as the process flow, equipment layout, pipeline routing, equipment lifting, equipment maintenance, and evacuation routes. Through thorough discussions and exchanges among the participants, over 150 suggestions for optimization were put forward, providing an important basis for the optimization of the project design. The person in charge of the Hualu project stated that going forward, the design plan will be refined in strict accordance with the review comments, and the layout of equipment and pipelines will be optimized to ensure the high-quality implementation of the project. The successful completion of the 30% scale review for the ethylene oxide plant and the polyether superplasticizer monomer plant represents an important milestone in the project design, laying a solid foundation for the subsequent in-depth reviews at 60% and 90% scales as well as for the project construction. The 1 million tons per year high-end chemical new materials project of Yulin Energy Fine Chemicals is located in the South Area of the Qingshui Industrial Zone in Yushen Industrial Park, 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.
It is understood that the 4 million tons per year CCS demonstration project operated by Yulin Chemical Company of Shaanxi Coal Group adopts a modern clean coal technology approach characterized by \"intensification, large-scale operation, clean utilization, and efficient use.\" Carbon dioxide is separated from its source of emission, then compressed and cooled using water cooling, before being transported through high-pressure pipelines and injected underground for permanent storage, thereby preventing it from entering the atmosphere over the long term. The project is implemented in three phases; the first phase consists of a 400,000 tons per year CCS demonstration project and a 400,000 tons per year pilot test project ； The second phase is the development of million-ton-scale CCS technologies and engineering demonstrations ； The third phase is a 4 million tons per year CCS demonstration project. Once completed, the project will be able to capture 4 million tons of carbon dioxide per year, thereby helping to alleviate the carbon dioxide emission issues in the coal chemical industry. “For energy and chemical enterprises to achieve high-quality development, a major challenge is carbon emissions. The successful progress of this project will offer more new avenues for carbon emission reduction and sustainable development in the coal chemical industry. ”Song Shijie, assistant to the general manager of Shaanxi Coal Group and chairman of Yulin Chemical Company, said that the unique geological structure of the Ordos Basin provides excellent conditions for storage. It is hoped that through the implementation of this project, the geological characteristics, sequestration capacity, and technical approaches related to sequestration spaces in the Ordos Basin can be clarified. At the same time, a top-tier demonstration site for carbon dioxide emission reduction in the northwest region will be established, so as to enable state-owned enterprises to make their due contribution to reducing carbon dioxide emissions. Next, Yulin Chemical Company of Shaanxi Coal Group will focus on the goals of green and low-carbon development by accelerating the construction of CCS projects. It will contribute to the advancement of the high-end energy and chemical industry parks in northern Shaanxi toward more sophisticated operations, a greater emphasis on materials production, and integrated development across the entire value chain, thereby helping to create a complete green industrial chain for the deep processing of coal.
