The volume of the solvent regeneration tower is 101 cubic meters. How is the hourly processing capacity calculated?
The main consideration is to keep the gas-phase space velocity below a reasonable level, such as 0.7 m/s.
Each type of tower has its appropriate space velocity

Assume the tower height is 22 meters (excluding the height of the base), with each floor being 0.6 meters high; there are 27 floors, so the total height is 16.2 meters. There are also upper and lower sections of the tower that are not occupied, so the total height should be fairly close to this value. Based on this estimate, the diameter of the tower should be 2.4 meters, and the cross-sectional area of the tower barrel is 4.5 square meters. 2. Based on the capacity calculations of our plant’s several amine regeneration towers with different diameters (1.6/1.8/3.0 meters), a design capacity of around 120 tons per hour should be appropriate. 3. The steam consumption is assumed to be 100 kilograms, which corresponds to 12 tons of steam per hour; I’ve seen designs that calculate only the space velocity of the first tray at the bottom of the tower. 12000/18*22.4/3600=4.15 Nm3/s; bottom temperature: 120 degrees; bottom pressure: 2.2 kilograms (absolute pressure) ; Then 4.15*393/273/2.2=2.7m3/s ; 2.7/4.5=0.6 m/s, a roughly similar calculation result. What I’m talking about here are general design considerations; the actual steam consumption in real-world designs or operations can vary to some extent. Factors such as a decrease in performance as the operation period of the device lengthens, as well as the impact of the quality of the amine solution on the degree of foaming, also play a role.
