How to calculate the residence time of liquids in a hydrolysis tower
Thread Content
For the ordinary tray tower using the Stamicarbon carbon dioxide stripping method that we designed for the Fourth Chemical Research Institute, the volume is 49 m3 with 21 trays; so how is the residence time of the liquid in the hydrolysis tower calculated? For example, if the desorption volume is 30 m3, then the residence time of the liquid in the hydrolysis tower is 49/30 = 1.633 hours, right?

Original poster, for a more accurate calculation, one should take the overflow dike height of 21 trays, multiply it by the area of each tray and then by 21, and finally divide that result by the hydrolysis volume of 30 M3. It’s advisable to check the design documents for accuracy; this is just for reference.
