酯化釜设备故障时的工艺控制

介绍了酯化釜设备故障情况,如酯化釜液位计故障,酯化反应泵机封EG内漏及对生产的影响。指出了在故障情况下稳定生产的对策,包括利用相关工艺点变化间接控制酯化二室液位及酯化机封泄露时羧基的控制。

Technologic control when esterification reactor equipment fault

The esterification reactor equipment fault situations such as esterification reator liquid level gauge fault and esterification pump mechanical seal inner leakage and their influence on production were introduced.The countermeasures for the steady production under the fault situations were pointed out including using related processing point change to indirect control of the esterification Ⅱchamber liquid level and the control of carboxyl when esterification mechanical seal leakage.
