Decreases or increases in mass for individual droplets are linked by their combined influence on vapor concentrations. Experiments conducted with mineral oil mist demonstrate that the model predicts evaporation accurately. The amount of vaporization will depend on the initial concentration, size distribution, and composition of the mist. Substitution of an alternative oil as a machining fluid may decrease evaporation considerably. Applied Occupational and Environmental Hygiene.
Many industrial processes generate mineral oil mist.
Current control technologies focus only on removing the mist droplets from the air. However, if these droplets evaporate, the vapor can pass through a collector designed to remove droplets alone. The purpose of this study was to determine the extent of evaporation for mineral oil droplets introduced to a mist collection system. After the system was loaded with mist, additional vapor samples were taken without mist injection to determine the amount of evaporation from mist-loaded collector components. Many industrial processes generate metalworking fluid mists.
