摘要
对苯二甲酸装置反应尾气中含有醋酸甲酯和PX等有机物,原工艺是通过RTO燃烧系统处理后再碱洗放空;但由于RTO系统不好用,且正常使用时燃料消耗也高,因此根据同类装置的经验和实际检测情况,增设一套醋酸甲酯回收系统,效果显著。
The article introduces EPTA process flow and existing problems and gives a solution plan. FFA reaction off- gas contains organic matters such as methyl acetate and PX, which were processed in RTO combustion system and excluded after caustic wash in original process method. Considering that RTO system is not convenient for usage with high fuel consumption in normal usage, a set of methyl acetate recycling system is added according to experience of similar systems and actual inspection situation and has been in operation currently with remarkable effect.
