How to determine the minimum liquid level of the tower reactor in the design?
What is the tube speed generally considered for the feed pipe of the thermosyphon reboiler matched with the tower?
How to determine the minimum liquid level of the tower kettle: Determine the residence time at the bottom of the tower, generally 15-30 minutes is enough.
According to "Practical Process Design of Chemical Plants", the liquid flow rate range entering the reboiler tube is: 1~4.5ft s-1 (approximately 0.3~1.4m/s) under atmospheric pressure 0.4~1 ft s-1 (approximately 0.12~0.3m/s) under vacuum operation
For the minimum height, the minimum circulation volume must be ensured, the dynamic pressure head of sufficient water must be ensured, and the vaporization rate must be calculated. This post was last edited by Albertlu on 2009-2-19 21:10 ]
