煤基甲醇装置改造为乙二醇装置可行性分析

Analysis of the Feasibility of Transforming 25×10~4t/a Coal-based Methanol Plant into a 20×10~4t/a Ethylene Glycol Unit

分析了乙二醇市场情况,对乙二醇生产技术进行了比较,选择草酸酯法工艺路线,生产乙二醇。以某企业25万t/a煤基甲醇装置中现有的气化装置为基础,分析了将该装置改造为20万t/a乙二醇装置的可行性,综合考虑技术、经济等条件,认为此装置改造可操作性良好。

The market situation of ethylene glycol was analyzed, its production technologies compared, and the dimethyl oxalate route to produce ethylene glycol was chosen. The feasibility of transforming an existing 250 000 t/a coal- based methanol plant into a 200 000 t/a ethylene glycol plant was analyzed. Judging from such aspects as technology, economy and equipment modification, the project has good operability.
