On October 14, the 30% scale model review meeting for the olefin separation and 1-butene unit of Phase 1 of Yulin Chemical’s Phase II project was successfully held. The meeting focused on a specialized in-depth review of the 30% model of the 3 units. A total of 28 participants, including those from the Olefins Department, Project Management Department, China Global Engineering Co., Ltd., and industry experts, conducted a comprehensive and thorough evaluation based on four key aspects: the rationality of the unit layout, compliance with safety and environmental standards, the scientific nature of the process design, and the ease of operation. This evaluation laid a solid foundation for subsequent optimization and construction of the units. Focusing on the core layout, the review team gives top priority to assessing the safety and rationality of the overall layout of the installation, ensuring precise control over the spatial planning of key equipment. Optimize equipment layout by considering equipment size, weight, and installation procedures ； Verify the lifting capacity and turning radius to ensure the installation of large equipment. Regarding the direction of the pipe corridor, verify the intersections with the main and secondary roads within the facility ； At the same time, verify the safe distance between the pipe gallery and surrounding buildings to ensure that road transport vehicles do not collide with the supports of the pipe gallery. Pay special attention to reviewing the safety clearance distances between key buildings such as cabinet rooms and power distribution rooms, as well as equipment areas, to ensure they are kept away from devices that handle flammable and explosive materials. Focusing on critical systems, and with an eye on the environmental compliance of the equipment as well as the convenience of subsequent operation and maintenance, the review team conducted a thorough examination of the core auxiliary systems. By ensuring air circulation within underground tanks, potential safety risks associated with the accumulation of flammable/toxic gases in low-lying areas are reduced. Implement the collection of liquid accumulated at the bottom of tanks to prevent dual risks to environmental protection and safety caused by the accumulation of process media. In accordance with the principles of \"proximity\" and \"spatial suitability\", the maintenance areas for various types of equipment are reviewed to ensure the adequate size and load-bearing capacity of the maintenance platforms ； Leave horizontal and vertical space for the heat exchanger core extraction to prevent collisions with surrounding pipelines or structural components. Refining process details: In addition to the overall layout, the review team focuses on the logical consistency of the details within the process system, to ensure that the design meets the actual production requirements. By focusing on key pipelines such as steam, flare gas, and condensate transfer, and paying particular attention to the parallel spacing between these pipelines, safety accidents caused by leaks can be prevented. The layout is optimized from the dual perspectives of \"process smoothness + operational convenience,\" enabling operators to conduct quick inspections and thus address equipment failures swiftly. Verify, item by item, the operational and maintenance details for equipment such as valves and heat exchangers. During this 30% model review, a thorough evaluation carried out through multi-disciplinary collaboration identified various potential issues such as unreasonable valve placement, inappropriate pipeline heights, structural steel platforms, and obstructions in personnel passages; design corrections were required as a result. This led to the establishment of a coordinated mechanism focused on design optimization, risk prevention, and improved operational efficiency. Next, the Olefins Department will use the results of this review as a basis to continuously improve the subsequent design stages, thereby helping to achieve the goals of \"safety, environmental protection, and efficiency\" in the construction of the olefins separation and 1-butene production facilities.
