C2多了,塔压高。放火炬或至低压管网,保持塔压不变,适当加回流,控制重组份到塔顶。

降低塔釜温度,在塔压稳定的情况下降低回流!

轻组分占比增大,按理说塔釜温度不是应该降低么,再认为降的话不是更低了么
Reply #62018-06-28
如果只是C3和C4的占比变化了呢,C3占比增加了
Reply #72018-06-29
是的,要撤点塔釜热,不然回流就得增加:)
Reply #82018-06-29
在塔压不变的情况下,塔釜的温度不会变吧,撤点塔釜热是对的

进料变轻,轻组分比重变大,首先是整塔的组分分布变化为轻组分占得比重增加,塔釜也是,组分变轻便不需要太多的加热负荷便能使之气化,故再沸适当减弱,整个塔组分较之前清,灵敏板温度往低里调整;再说塔顶,塔顶轻组分多则需要更多的冷凝负荷,故应加大冷凝器的负荷;再说采出,那就简单了,塔釜重组分才出量降低,塔顶轻组分采出量加大即可,虽然简单,但是这一步调整最为关键。

噢噢,大概懂了,谢谢啦!:lol
