Ultraviolet transmittance(UV) of glycol product from ethylene oxide/ethylene glycol(EO/EG)unit often appears fluctuation, main reasons to cause the result have been analyzed, such as existing dissolved oxygen, high pH ,high aldehydes content, high temperature, existing particle materials and nitrogen impurity ,and so on. Some measures were put forward, such as removing impurities, optimizing system pH and MEG refining tower operation, clearing reboiler and so on.
