2¿组分精馏,顶产品不合格,怎么解决?麻烦请教大家谢谢!

增加板层数,减少蒸发量

看是怎么不合格的,产品纯度要求是多少
Reply #42018-06-22
说得详细一点,具体工况和操作条件都讲讲,大家才能帮你啊

生产中一般是加大顶回流,视底指标情况减小上升蒸汽。

要看具体的吧。增加理论板层数;加入共沸剂;减压······
Reply #72018-07-16
要么增加板数,要么增加能耗,设备可以改造,否则只能加回流和蒸汽

9首先需要弄清是哪种原因造成的,一般情况是增加回流量
Reply #92018-07-27
1如果严重不合格,应停进料,加大回流。如果只是微量不合格,只需加大回流量

*一般增加回流量将高沸点物料压下去,如果负荷大了造成的则要减少蒸发量
Reply #112018-08-07
*工艺操作就增加顶回流吧,正常应该是合格的吧?是不是原料组分改变了
Reply #122018-08-07
*不具体,不过可以通过调节真空度,回流比,蒸汽量等,简单说,要保顶或保底都容易,难的是保顶保底
Reply #132018-08-07
*那你的产品不合格是有重组分还是轻组分?降低蒸馏速度,降低加热,减少回流量,估计应该可以,如果是轻组分,那就要看前面的精馏了,降低回流比试试。"
