Stirring tank of extraction unit
Thread Content
May I ask why, in the extraction unit’s stripping tower, the bottom temperature is controlled by using a cascade control system based on the bottom pressure and the flow rate of condensate water from the bottom reboiler, in order to maintain this temperature? Can’t we simply use the condensate water control principle of the bottom reboiler?
Cascade control provides smoother operation with minimal fluctuations
Is the condensate flow rate being used? Isn’t it the reboiler level control?
How is the temperature controlled using the reboiler level?
