Xiangqi,
There is another type of wet scrubber (WEV) better compared to Venturi, less pressure drop and water consumption, and higher separation efficiency and smaller foot print. If you have PSD data, the separation efficiency can be calcualted based on pressure drop. This scrubber employs a...
Yes, it's true. Since the liquid viscousity is one of the important factors to calculate the separation efficiency. The surfactant might change the surface friction (viscousity) of the droplets.
Hope this give you soem clue.
