摘要
提高煤制乙二醇产品的紫外透光率是煤制乙二醇行业长期的研究课题。在实际应用中发现在乙二醇精馏系统中加碱可使乙二醇产品紫外透过率在220 nm处得到显著提高,该技术能广泛应用于煤制乙二醇企业。
It is a long-term research topic to improve the ultraviolet transmittance of coal-to-ethylene glycol products. In the practical application, it is found that adding alkali in the ethylene glycol rectification system can significantly improve the ultraviolet transmittance of ethylene glycol product at 220 nm, which can be widely used in coal to ethylene glycol enterprises.
