摘 要 甲醇作为及其重要的有机化工原料，是碳一化学工业的基础产品，在国民经济中占有重要地位。
近年来，随着工业生产甲醇的开发，特别是甲醇燃料的推广应用，甲醇的需求大幅度上升。该设计的主要内容是对甲醇合成工段进行进行物料衡算、热量衡算和设备计算。该设计本着符合国情、经济、环保的原则，采用焦炉煤气为原料，运用Lurgi工艺合成法，来合成甲醇的，并对主要的设备合成塔进行工艺计算和选型。此外做出了带控制点的工艺流程图和合成塔设备图。
关键词 甲醇 合成 工艺设计

Abstract PL as an important organic chemical raw materials, the carbon chemical
industry products plays an important role in the national economy.
In recent years, with the development of industrial production of PL, the promotion and application of PL, PL demand increased significantly. The design of the main contents of the PL synthesis section in the material balance, heat balance. Design the principle of line with national conditions, economic, and environmental protection, the use of coke oven gas as raw material, the use of the Lurgi process synthesis to the synthesis of PL, and major equipment synthetic tower technology calculation and selection. I made a diagram of the process flow diagram of the control points and synthetic tower equipment. Key words methanol synthesis process design
