Generally, control at 80% level, or a higher level.
May I ask about the installation location of the reboiler level gauge?
A reboiler is the same as a heat exchanger; it cannot be equipped with a level gauge.
The condensate level you’re asking about indicates that you have a condensation tank set up.
The steam flow rate to the recent reboiler is experiencing large fluctuations!
A slightly higher liquid level can stabilize the steam volume; an excessively high level will affect the heat exchange efficiency. Generally, the liquid level is set based on the processing capacity of the distillation tower
There is no specific indicator for the liquid level of steam condensate in the reboiler; it certainly cannot be too low, otherwise the steam will be carried away through the condensate pipes. The level of the condensate determines the size of the heat exchange area, and it is by controlling the amount of condensate sent away that the steam consumption is regulated. When control valves are installed directly on the steam pipes, the temperature of the condensate will definitely remain low at all times
The liquid level in the bottom reboiler is generally controlled at around 40%
