Absorption tower issues
Thread Content
The absorption tower remains at a constant gas velocity. Is flooding more likely to occur when increasing or decreasing the liquid flow rate?
Reply to 1# mg8868: Increasing the liquid flow rate can easily lead to flooding. A packed tower has a certain degree of porosity; it’s like a bottle with an opening at the bottom, and enough water volume is required to fill it. When the liquid flow rate increases and exceeds the rate at which the liquid falls to the bottom of the tower, a large amount of liquid accumulates in the packing layer; the dispersed liquid phase becomes a continuous one, which hinders the upward movement of the gas. At this point, the pressure difference across the tower rises significantly, and the gas carries away a large amount of liquid as it exits the tower, resulting in flooding.
Of course, increasing the liquid flow rate makes flooding more likely to occur.
