单体泵故障后生产的稳定控制

Production stable control when monomer pump fault

为解决聚酯生产装置中单体泵紧急故障时带来的问题,通过分析,采取提高酯化Ⅱ的压力,接入临时管线确保稳定剂的加入,对工艺温度进行适当调整,确保正常的酯化率,保证了系统的稳定和产品品质的稳定。

In order to solve the problems occured when PET production monomer pump was carried out. By increasing the pressure of esterification Ⅱ, accessing temporary pipeline er adding, proper adjustment of the process temperature to ensure the normal esterification emergency fault, analysis to guarantee the stabilizrate, the stable control of the system and product quality was guaranteed.
