60万吨年MTO生产车间工艺设计

60 万吨/年 MTO 生产车间工艺设计60 万吨/年 MTO 生产车间工艺设计摘 要I随着石油产业的快速发展，我国对烯烃的需求量在逐步增大，尤其是对低碳烯烃的需求，而我国石油的供给不能达到自给自足的状态，需要大量地进口石油来制低碳烯烃。所以，大力发展 MTO 技术尤为重要。本设计的题目为 60 万吨/年 MTO 生产车间工艺设计，本设计采用以非石油为原料的低碳烯烃生产路线甲醇制烯烃技术代替石油原料制烯烃，这方法可减轻我国化工产业对石油的依赖程度，MTO 技术主要用于生产低碳烯烃乙烯和丙烯。本工艺设计采用UOP(美国环球油品公司)的 MTO 工艺，在设计中将对 MTO 工艺中的生产工段分别进行工艺设计，本设计还根据具体生产要求对工艺流程进行物料衡算和主要的生产设备进行热量衡算，以及对工艺中的主设备进行尺寸计算和选型。关键词：MTO 工艺；甲醇制烯烃；低碳烯烃；乙烯600,000 tons / year MTO production workshop process designIIAbstractWith the rapid development of the petroleum industry, China's demand for olefins is gradually increasing, especially for low-carbon olefins, and China's oil supply cannot reach a state of self-sufficiency. It is necessary to import a large amount of oil to produce low-carbon olefins . Therefore, vigorously developing MTO technology is particularly important.The title of this design is the process design of the 600,000-ton / year MTO production workshop. This design uses the non-petroleum-based low-carbon olefin production route methanol to olefin technology to replace petroleum raw materials to olefins. This method can reduce China's chemical industry Depending on the degree of dependence, MTO technology is mainly used to produce low-carbon olefins ethylene and propylene. This process design uses the MOP process of UOP (American Universal Oil Company). In the design, the process design of the production section of the MTO process will be separately carried out. This design also performs material balance and main produ...
