How to calculate the space velocity of an absorption tower
Thread Content
I would like to ask everyone: how is the space velocity of an absorption tower calculated? Are the calculation methods for packed towers and plate towers the same?
The air volume divided by the cross-sectional area of the tower gives the gas velocity in the empty tower. A packed tower is the same as a plate tower.
It is necessary to calculate the empty tower gas velocity at the top, middle, and the area with the highest temperature inside the absorption tower separately. Generally, these locations are quite critical; sometimes the flow velocities at the top and bottom can differ by many times!
The empty tower gas velocity is obtained by dividing the hourly air volume in M3 by the tower cross-sectional area in M2, and then dividing the result by 3600. They’re all the same
