Double wet-scrubber??
Thanks for your input, siretb! Energy is not a problem. I already sent the request to meaure the pressure drop through Venturi. The emission gas has a very high tempperature (57-59 oC) which carries lots of vapor from the system. The problem is the limited fresh make-up water. I know the right...- xiangqi

Double wet-scrubber??
Many thanks to the kindly reply. To mbritt: Yes, the clay is neutrally charged, but the temperature is at about 65 oC - coming from the spray dryer. You raised good point about the contact time in the Venturi, and I am not sure we have 0.5 sec contact time. The air flow is very high (maybe...- xiangqi

My plant has a spray dryer for clay product. The dust is intercepted by cyclones at moderate efficiency (around 85% - my estimation) due to small particle size distribution. The system has a Venturi type scrubber to reduce the PM (particulate matters) emissions (regulation: 100 mg/m3). From...- xiangqi
