What are the factors that affect the efficiency of a stripping tower?
Thread Content
The original equipment is not a standard stripping tower but an intermittent synthesis reactor equipped with a tower body. Now, we want to upgrade this equipment by using nitrogen to strip away the small amount of ethanol remaining in the reaction mixture (with a boiling point of around 200 degrees). I would like to ask the experts how we can make these improvements to facilitate the removal of the residual ethanol I hope to use as little nitrogen as possible.
In the case of stripping, nitrogen must be used to ensure maximum contact between the bubbles and the liquid, thereby reducing the partial pressure and allowing ethanol to be extracted. Whether there are trays in the upper section of the tower or not, allows high-boiling-point substances to flow downward from the upper part of the tower, while nitrogen passes through the mesh at the bottom of the tower; heat then evaporates the ethanol... For other methods, feel free to share your ideas below...
As a supplementary point, a circulation pump should be installed at the bottom of the tower; the flow rate required will depend on the feed rate to the tower and the tower pressure
