During the exhaust gas absorption process, how to calculate the air volume processed by the exhaust gas absorption tower?

Please tell me how to calculate the air volume processed by the exhaust gas absorption tower during the exhaust gas absorption process? Like the treatment air volume of hydrogen bromide? This post was last edited by DAC Junlintianxia on 2007-11-13 14:10 ]
Generally speaking, the gas flow velocity in the tower is 3m/s (natural wind speed) for calculation. In addition, refer to the dissolution rate of gas in the absorbent. If the absorption rate of the absorbent is high, the flow rate of the gas can be appropriately increased!
According to some empirical data, the general gas velocity at the top of the tower is 0.457~0.762m/s and the vacuum distillation speed at the top of the tower is 1.8m/s.
The flow rate of the gas is determined based on the dissolution rate of the gas in the absorbent!
The flow rate selection in the tower is used to determine the tower diameter, not the air volume. To determine the total air volume, the processing volumes of each absorption point need to be added up and then multiplied by an amplification factor (taking into account air leakage). Just like the flow rate on the main Yangtze River is the sum of the flow rates of all direct currents.
