From November 5th to 8th, the PID review meeting for the detailed design of the wastewater recycling and evaporation crystallization systems for Shaanxi Yueneng Fine Chemical Materials Co., Ltd.’s 1 million tons per year high-end chemical materials project was successfully held at Saiding Engineering Co., Ltd. Ma Shaojun, a member of the Party Committee and deputy general manager of the company, attended the meeting, while industry experts and relevant personnel from the Production Technology Department participated in the review. The project teams from Saiding Engineering Co., Ltd. and LightLead (Shanghai) Technology Co., Ltd. provided technical support and cooperation throughout the entire process. This review session focused on in-depth discussions of key aspects such as the completeness of PID drawings, the accuracy of design parameters, the rationality of the process flow, the rigor of material balance, the scientific nature of instrument configuration, and operational safety standards. During the four-day evaluation process, the experts and technical personnel involved engaged in thorough discussions to reach a consensus, submitting over 120 constructive review suggestions. These suggestions helped to identify and avoid various potential technical and security risks, thereby significantly improving the reliability and safety of the device design and laying a solid foundation for the subsequent detailed design work of the project. To ensure that the outcomes of the review are put into practice, the company has assigned professional technical personnel to monitor the progress of the improvements throughout the process. By combining regular inspections with targeted coordination, efforts are made to effectively address the identified issues, with the goal of achieving closed-loop management for all issues by the time of the next review, thereby ensuring the high-quality advancement of the project. 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 annual comprehensive energy consumption equivalent of the project is 269,000 tons of standard coal. The construction scope includes a 400,000-ton/year DMTA plant, an 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 various supporting and auxiliary facilities. The 1 million tons per year high-end chemical materials project of Shaanxi Yueneng Fine Chemical Materials Co., Ltd. includes a 400,000 tons per year polycarboxylate superplasticizer production facility, which consists of two main units: the polycarboxylate superplasticizer production unit (1190) and the polycarboxylate superplasticizer blending plant (1191). The polycarboxylate superplasticizer production facility (1190) is equipped with 4 mother liquor synthesis lines, resulting in an annual total production of 275,000 tons of mother liquor. Of this amount, 75,000 tons are used to produce superplasticizers through mixing with other substances, while the remaining mother liquor is sold directly. For mother liquor compounding (1191), 1 production line is set up, with an annual output of 200,000 tons.
