煤制乙二醇工艺技术及其生产装置运行分析

Analysis on coal to ethylene glycol technology and operation of its production unit

以安徽昊源化工集团有限公司30万t/a煤制乙二醇装置为例,简单介绍了该装置的工艺原理及基本工艺流程,详细分析了该装置的原料、辅材消耗情况,羰化合成催化剂、加氢催化剂的性能及应用效果,乙二醇产品、碳酸二甲酯和乙醇副产品的产品质量情况,硝酸还原装置的技术参数。运行结果表明,整套装置的物料消耗较低,催化剂性能良好,产品、副产品指标达到相关国标要求。

Taking 300000 t/a coal to ethylene glycol unit of Anhui Haoyuan Chemical Group Co.,Ltd.as an example,the process principle and basic process flow of the unit were introduced briefly,with detailed analysis on the consumption of raw materials and auxiliary materials,the performance and application effect of the carbonylation synthesis catalyst and hydrogenation catalyst,the quality of ethylene glycol product,dimethyl carbonate and ethanol by-products,and technical parameters of nitrate reduction unit.The operation results showed that the material consumption of the whole unit was low,the catalyst performance was good,and the product and by-product parameters met the relevant national standards.
