摘要
甲醇作为及其重要的有机化工原料,是碳—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作用,甲醇的需求幅度上升,用甲醇作为新的石化原料来源已经成为一种趋势。
目前生产甲醇的主要原料是煤和天然气,甲醇的生产工艺过程分为合成气的制造、甲醇的合成好精制三部分。该设计的主要内容是对甲醇合成工段进行物料衡算、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,采用天然气为原料,运用了Lurgi工艺合成法,。
关键词:甲醇合成工艺设计
Abstract
PL as an anic 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, PLdemand increased significantly,With PL as the new sources of petrochemical materials has e a trend.
Currently the main raw material production of methanol was from coal and natural gas ,methanol production process was distinguished into three parts,such as the production of synthesis gas,synthesis and refining of design of the main contents of the PL synthesis section in the material balance,heat the principle of line with national conditions economic,and environmental protection,the use of natural gas as raw material,the use of the Lurgi process synthesis of PL,and according to the annual output of 52000 tons of methanol process design capacity of 52000 tons of methanol synthesis section.
Key words: methanol synthesis process design
