摘要
分析了PTA装置残渣薄膜蒸发器跳停的原因,提出预防措施。通过稳定进料量,及时冲洗进料线,避免进料浓度过高,保持打浆罐出料泵出入管线畅通等,操作平稳率增加,打浆罐中醋酸含量大大降低。
According to the structure, technology and operation characteristics of residue film evaporator of PTA plant in Luoyang Petro-chemical Complex,the trip reasons were analyzed,the precautionary measures were put forword.By stabilizing the in-feeding quantity,washing the in-feeding line in time,avoiding the in-feeding high concentration,keeping the beating tank discharging pump entrance and out line unblocked,the operation smooth rate is increased,the AcOH content in beating tank is sharply reduced.
