提前循环能否建立起来?
Reply #32019-12-15
这不存在提前不提前,分馏开工的时候都是一直等着反应走。等着反应催化剂三器流化正常后,催化剂赶到再生器,开始拆大盲板,这时候要保证油浆的液位和循环量,特别是上反塔的量。这时候分馏是塔外循环,不存在顶循,中段提前建立,这样是不允许的。等到大盲板,改塔内,建立各个循环,调整等

我只是个菜鸟,不对的地方,大家多多指教
Reply #52019-12-15
关于这个问题你要搞明白精馏塔建立回流的前提是什么? 有逐步上升的气相介质和逐步下降的液相介质才能确保各段回流的建立,如果只有下降的液相而没有上升的气相,这个时候轻组分就会往下压,其实对于分馏塔的开工会引起很多麻烦的,无论从产品质量或生产操作都是一样的! 既然是新人,建议还是把一些相关的理论知识巩固下再做进一步的研究,否则很多问题会越来越模糊,越来越没有方向感。

我装置的做法是中段管线提前充入柴油,顶循环管线充入汽油,这样反应进料,塔温度起来后,中段和顶循环泵能更快上量正常运转。

主要看有没有建立起来的组分
