Fog formation in condensers

Fog can form when a vapor mixture cools below its saturation temperature, in a similar manner to atmospheric fog formation. In condensers, it takes place when the heat transfer rate from the cold surface exceeds the mass transfer rate to the surface. Fog droplets range in size from 0.1 to 40 p,m (78, 380). Below about 3 to 5 p.m, the droplets tend not to collect on the cool surface but remain with the vapor and pass down the vent line in partial condensers. Reported measurements (381) suggest that in some cases, 20 to 40 percent of the mixture can be in the form of fog droplets.
