Simulation calculation of wet scrubber towers in flue gas desulfurization
Thread Content
Dear experts: I have recently come into contact with technologies for purifying flue gas generated during the incineration of hazardous waste. After most of the dust is removed from the flue gas using a dust collector, it enters a wet packed-bed scrubber to have the acidic gases removed from it; these acidic gases include HCl, HF, and SO2. Since the temperature of the flue gas entering the wet scrubber is 150–160°C, sodium hydroxide solution is used for spraying. After that, the wash liquid is cooled before being sent back into the scrubber for recycling. I would be grateful if you could advise me on how to simulate this process!
This is generally not simulated; the result is directly given using separation sep. The scrubber either converges uselessly or does not converge at all. Generally, equipment manufacturers calculate it themselves.
