聚酯工厂乙二醇罐区挥发性有机物治理方案探讨

Discussion on the VOCs Treatment of Ethylene Glycol Tank Farm in Polyester Plant

随着大气污染物排放国家标准的要求越来越严格,如何处理PET工厂排放的不达标乙二醇挥发性有机物（VOCs）问题急需解决。介绍了乙二醇储罐VOCs排放浓度的计算方法,就利用PET工厂的气提装置处理乙二醇罐区VOCs的可行性及安全设计要点进行了相应论述。

With the increasingly stringent requirements of national standard for air pollutant discharge, howto deal with non-compliance of ethylene glycol VOCs in PET plants needs to be solved urgently. The calcu-lation method of the existing ethylene glycol emission was introduced, and the feasibility of EG VOCs treat-ment by steam stripping device and the safety design points of VOCs in ethylene glycol tank farm were dis-cussed.
