摘要
论文主要论述了MTBE生产过程中醇烯比不合适需调整时的征兆迹象及调整方法。即通过观察反应器床层的温度的变化,反应器上下差压的变化,催化蒸馏塔灵敏板温度的变化,催化蒸馏塔底温度的变化,甲醇萃取塔及回收塔负荷和循环甲醇量的变化,MTBE产品中碳四、碳八、MSBE含量的分析变化,原料中异丁烯的含量、甲醇的纯度变化等这些迹象,提前预判,通过调节醇烯比这个手段进行调节,避免操作波动和引起事故,从而保证装置安稳长满优生产。
The warning signs and adjustment method when the alfin ratio was not suitable in the process of MTBE production and needed to adjust were discussed. By observing the change of reactor bed layer temperature,the change of the reactor and the differential,the change of the sensitive plate temperature,the change of catalytic distillation bottom temperature in catalytic distillation tower, the change of the circulation quantity of methanol in methanol extraction tower and recovery tower load,the change of contents of carbon four,carbon eight,MSBE carbon in MTBE product,the change of methanol content,the purity of raw material,through anticipation,adjusting the alfin ratio adjusted by the means of this,accidents caused by fluctuations and operation can be avoided,so as to ensure the plant with optimal production.
