Recently, the foundation design review meeting for the first process unit of the first phase of the olefins, aromatics, and deep processing project under Shaanxi Coal Group Yulin Chemical Company’s 15 million tons per year demonstration project for clean and efficient conversion of coal by different grades (referred to as “Phase 2, Phase 1 project”) – specifically, the foundation design review meeting for the MTO unit – was held at Sinopec Guangzhou Engineering Co., Ltd. Xie Wuqiang, deputy general manager of Yulin Chemical Company of Shaanxi Coal Group, along with experts and relevant personnel from the Production Department, Project Management Department, Olefins Department, Electrical and Instrumentation Department, Emergency Management Center, Quality Supervision and Inspection Center, Sinopec Guangzhou Engineering Co., Ltd., Pucheng Clean Energy Chemical Co., Ltd., and China Coal Shaanxi Energy Chemical Company, attended the meeting. At the meeting, the attendees listened to a presentation by the design institute on basic design aspects such as floor and equipment layout, process flow, technical optimization, and design principles. Subsequently, in accordance with requirements such as the \"Regulations on the Design Content for Foundations of Petrochemical Plants,\" a thorough review of the project’s foundation design was carried out. Comprehensive and detailed discussions were held on aspects including the project’s production process, overall layout, selection of equipment, electrical and instrumentation systems, safety and environmental protection measures, as well as the estimated investment costs. Drawing on industry experience, the expert group offered optimization suggestions regarding design rationality, safety, and operability, emphasizing the need to further reduce energy and material consumption, improve environmental sustainability, and create a model project that leads in terms of its entire life cycle. It is understood that for Phase I of the Second Phase project, the designed methanol feed rate for the 1.5 million-ton/year methanol-to-olefins unit is 303.75 tons per hour. The annual operating hours are 8,000, and the unit’s operating flexibility ranges from 70% to 110%.
