Seeking advice on the level control problem in liquid-liquid extraction
Thread Content
I have some questions regarding the control scheme of the liquid-liquid extraction tower that I’d like to ask. During full-operation mode, why is the top pressure controlled by the draw rate at the bottom of the tower, while the level at the bottom of the tower is controlled by the draw rate at the top? What are the advantages of this control scheme?
Can’t understand the ball game........ Just watching
The bottom boundary level is controlled through bottom withdrawal; what are the disadvantages of controlling the top pressure through top withdrawal?
Cao Shujian is such an idiot; he barely knows anything about Miao Li Kai...... :P
There’s only one control scheme; it has no drawbacks and is better than manual control
Hello, old electrician Jake, it’s great to see you again.
Based on the process characteristics, it is classified into cases where the heavy phase is the continuous phase and cases where the light phase is the continuous phase； Extraction towers are also mainly divided into sieve plate towers, packed towers, rotary disk towers, etc. The control schemes will vary.
