How to control a distillation tower and operate it smoothly? Please share your experience
Distillation towers have a wide range of applications. The so-called experience lies in strictly following the operational procedures, with control measures that allow for some flexibility; it is not advisable to try to achieve high yields and reduced consumption by operating on the edge of what is possible. By abiding by rules and regulations, the results will surely be stable. My experience shows that all sources of instability stem from creating problems for no reason. For reference.
Feed reflux, pressure, steam; nothing else
It refers to the stability of the reflux ratio, steam flow rate, and pressure. The output is stable. Send for inspection regularly; those that fail are sent back in their entirety.
The key to a distillation tower is maintaining stable pressure, stabilizing the vapor volume at the bottom of the tower, and keeping the feed rate within a certain range to prevent large fluctuations.
Keep flow, temperature, pressure, and level control from experiencing large fluctuations
