Methanol waste gas
Thread Content
Methanol waste gas at 5,000–8,000 mg/cubic meter, temperature of 10–40 degrees; the concentration is reduced to below 500 mg through washing with water. If 3-stage counter-current washing is used, with the wash water from the subsequent tower serving as the wash water for the previous stage, to what level can the methanol concentration be increased? How do I calculate it? Please help everyone
Depending on your requirements, methanol is highly soluble in water, so a single stage of scrubber is sufficient
The methanol concentration should be increased to the equilibrium concentration at that temperature. Level 1 is enough
Does anyone have equilibrium diagrams for aqueous solutions of acetic acid and methanol at different concentrations? Please send one
It’s possible to achieve around 20%–25%; we’ve done it before.
