第一酯化釜压力控制阀失灵下的生产控制

The production control under the condition of first esterification reactor pressure control value uncontrollable

介绍第一酯化釜压力调节阀突发故障,无法控制酯化压力,所采取的紧急措施。在尾气排放管线上加装一调节阀,调节不凝性尾气的排放量来控制酯化系统的压力,开车得以继续进行。整个酯化系统都在正压下运行,工艺参数作相应调整,酯化率和切片质量未受影响。

Some emergency measures were used,when the esterification pressure was unable to control,A control valve was added on the waste gas pipeline,the pressure of the esterification system was controlled by adjusting the discharge capacity of foul waste gas,the running of the machine was continued.The whole esterfication system worked under positive pressure,the process parameters were adjusted.There were no effect on the esterification rate and the chip quality indexes.
