"El aumento repentino del de flujo retroalimentado ha causado un problemao en la destiladora.",

Reply #32019-01-05

"Pidoto a los dioses. En la destiladora de propanoo, debido a un des desor en el instrumento de control oto de la automático, el flujo retroalimentado aumentó casi por un factor de a.倍。。回流温度为55℃，塔顶控制在56.1℃±0.5 。增加回流后，提馏段温度迅速降低，精馏段的温度升高。请问理论上应该如何解释这个现象？是否可以理解为过大的且温度过低的回流液体将上升的气相全部冷凝下去导致的？"

"Estoy de acuerdo con la segundo p de opinión,应该是过大的的回流比破坏了精馏段的气液交换平衡，相当于降低了塔板数，导致塔顶塔釜压降降低" "塔釜压降降低" "蒸发温度降低" "由于由于精馏段板数下降" "导致气体上升过快" "塔顶温度增加"

"Estoy de acuerdo，塔操作压力为0．．barbar作用问题发生的时候塔压一直保持在 "0．塔压从 "升到了 "．．．塔塔压压一直在 " "不知道我哪里理解错了。"
