Thread Content
On December 7, 2024, the process technology for Rongsheng New Materials (Zhoushan) Co., Ltd.’s 200,000-ton/year POE production facility in Jintang, which was developed by the R&D center of Zhejiang Zhiying Petrochemical Technology Co., Ltd. and engineered by Shanghai Zhiying Chemical Technology Co., Ltd., successfully passed the \"First Domestic Workshop on Process Safety and Reliability Assessment\" organized by the Zhejiang Chemical Safety Association. Commissioned by the Zhejiang Provincial Emergency Management Department, the demonstration meeting was organized by the Expert Advisory Committee of the Zhejiang Chemical Safety Association. Dong Guoqing, the convener of the committee, presided over the meeting, and 9 senior experts from relevant fields such as process engineering, equipment technology, automatic control, and safety within the province were invited to form an expert group to conduct a reliability assessment of the project. Yu Lin, the deputy chief engineer for processes at Rongsheng New Materials (Zhoushan) Co., Ltd., Xue Kuanrong, president of Zhejiang Ruizhi Holding Group, and other leaders, along with development and engineering designers from various technical fields, attended the meeting. At the meeting, Dong Guoqing first introduced the background of the conference and the project, while also setting high standards for the evaluation process. He emphasized that the expert group should approach the assessment meeting with a highly responsible, professional, precise, and objective attitude, and he provided guidance on the work to be carried out. Yu Lin, the deputy chief engineer for technology at Rongsheng New Materials (Zhoushan) Co., Ltd., provided an introduction to the background of the 200,000 tons per year POE production project as well as basic information about the project’s developer ； Zhejiang Zhiying gave a comprehensive presentation on the process technology and other aspects of the POE project. The high-temperature solution polymerization process technology discussed in this study has already undergone pilot and scale-up tests; it features a short reaction residence time, high safety and reliability, high catalytic activity, a high rate of comonomer incorporation, and high product concentration. This enables the safe, cost-effective, and long-term operation of production facilities. After inquiries and thorough evaluation, the expert group unanimously agreed to approve the review. The expert group believes that the production process of the 200,000 tons per year POE plant in Rongsheng New Materials (Zhoushan) Co., Ltd.’s Jintang New Materials project is the mainstream process used in both domestic and international production; it features mild reaction conditions, and its operation is safe, stable, and reliable, with mature technology ； This production process has been validated through pilot and scale-up tests, and studies have been conducted on the safety risk assessment of chemical reactions involved in the process, the thermodynamic analysis for scaling up the chemical reactor process, HAZOP analysis, and SIL grading analysis; the key process technologies are reliable.
