Pressure difference of CO2 and H2S absorption tower
Thread Content
Will the pressure difference increase if the gas flow rate is small?
The gas flow rate is small, and the tower pressure difference should be small and not increase.
What the second floor said is right. If the gas flow rate is small, the tower pressure difference will only become smaller and will not increase. The normal pressure differences of H2S and CO2 absorption towers are 0.07Mpa and 0.085Mpa.
If the air speed is too small, the pressure difference will increase in extreme cases: If the tray plate is not flowing smoothly and the gas velocity is too high, the pressure difference will also be large. The lowest value of the pressure difference should be within a gas velocity range.
