假设精馏塔进料温度、流量、组成都没有变化,侧线采出也没有变化,其他条件都不变,单纯提高底部热源,回流量会如何变化?该塔只是分离A、B两种组分。

回流量上升,塔釜液位相对下降

"현장에서 문제가 발생했음을 명확히 밝혀주세요. 만약 상승 증기량을 증가시키면回流液量是要减少的。因为上升蒸汽量多,相对与下流液体换热,液体被蒸发得多,回流的就少。一个塔分离的组分不一定是要两种,是要看塔器的结构的。供参考。

命题不准确,其他条件都不变这个说法就有问题吧,建议楼主AsAs跑一圈水和甲醇,自然就知道怎么回事了。

从单层塔板的相平衡来说,加再沸意味着上升气相增加,相对应就就需要增加液相,保证塔板的相平衡。但是塔的进料量未变化,这样操作提高了塔的负荷。而且会造成塔重组分上移。造成塔顶产品质量不合格,同时塔釜产品会损失。

从你描述的问题来看,塔有什么不正常吗?单纯想加再沸?
