煤基合成气间接法制乙二醇技术工艺探讨

Inquiry into Technology Process of Indirect Process for Coal Based Syngas to Ethylene Glycol

简要介绍了煤基合成气间接法制乙二醇的基本原理及主要特点,根据1 000 t/a中试装置实际试验情况,对工艺控制参数和出现的问题进行了分析和探讨。中试装置鉴定结果表明,该技术达到了国际先进水平,采用该技术建成的100 kt/a煤基合成气间接法制乙二醇项目已贯通全流程,生产的乙二醇产品各项指标达到了设计值。

A brief description is given of the fundamental principle and main characters of indirect process for coal based syngas to ethylene glycol, based on actual experimental conditions of 1 000 t/a pilot plant the process control parameters and problems arisen are analyzed and discussed. Appraisal result of the pilot plant shows that the technology has reached international advanced level, the indirect process of 100 kt/a coal based syngas to ethylene glycol project using this technology has interconnected full process, all indices of ethylene glycol products produced meet the design value.
