Calculation of methanol absorption tower
Thread Content
As the title suggests, I want to build a spray tower for removing methanol from exhaust gas. The concentration of methanol in the exhaust gas is 300 g/m³. There is a water tank at the bottom of the spray tower, and water from this tank is used in a cyclic process to absorb the methanol. I think water and methanol are mutually soluble. I’m not sure what the final concentration of water in the tank can reach. I wonder whether Henry’s law or Raoult’s law can be applied here; if so, how should they be used? I would appreciate some guidance from those who know more about this. Thank you
It mainly depends on pressure and temperature; the temperature should not be too high, room temperature is sufficient. Find the solubility curve in your own chemical handbook
