ABSTRACT:
Processes for the high efficiency removal liquid aerosols from gaseous streams and coalescing filters for carrying out such processes are provided. The filter comprises a porous medium having a critical surface energy less than the surface tension of the liquid to be removed and the dynamic film thickness of the liquid to be removed is from about 0.5 D to about 0.8 D, where D is the mean pore diameter of the porous medium, whereby, in operation, the correlation of the pore size with the dynamic film thickness of the liquid coupled with the relationship between the surface tension of the liquid and the critical surface energy of the porous medium provide high efficiency removal of the liquid aerosol with a minimum resistance of flow. The effluent typically contains 0.05 ppm or less, by weight, of aerosol.
