How does the evaporation device maintain a stable cycle
Thread Content
In an evaporation crystallization unit, the liquid level in the evaporator cannot remain stable, and operation cannot proceed in a steady cycle. Is it due to an imbalance between the amount of liquid added and that removed? What are some solutions from a process perspective? Thank you
There could be several reasons for this: the insufficient sensitivity of the automatic control valve can lead to large fluctuations; the amount of gas rising in the tower varies, resulting in unstable pressure differences; the volume of liquid returning to the tower fluctuates greatly; too many bubbles form in the liquid phase, causing boiling and unstable liquid levels
It might be due to instability caused by the liquid boiling
It is determined to be mother liquor foaming and material entrainment. The true liquid level cannot be measured. It is recommended to use an antifoaming agent.
