提高煤制乙二醇聚酯级产品回收率及产品质量的研究

Development and Application of Improving Recovery Rate and Product Quality of Pet Grade Products From Coal to Ethylene Glycol

文章简要介绍了煤制乙二醇聚酯级产品回收率及质量的提高情况,通过已运行装置,结合工艺技改优化对树脂工艺和液相加氢工艺处理聚酯级乙二醇后进行对比,阐述两者对现阶段聚酯级乙二醇产品质量及经济效益对国内煤制乙二醇发展的影响。

This paper briefly introduces the improvement of the recovery rate and quality of pet grade products from coal to ethylene glycol,and compares the resin process with the liquid phase hydrogenation process through the operation of the unit and the optimization of the process,the influence of the two factors on the product quality and economic benefit of pet grade ethylene glycol at present on the development of coal-to-ethylene glycol in China is expounded.
