3.4. Aerosol Formation

The physical state of liquid or solid particles suspended in air is known as aerosol. Atmospheric aerosol has long been studied and several classic books exist in this area. Even in industry, hazard exhibited by two-phase mixtures, aerosol, is often overlooked (Bowen and Cameron, 1999). It is widely accepted (Lian et al., 2011) that safety in process industry is also shaped by the presence of aerosol. Since aerosol cannot be treated as gas or liquid, assessing hazard associated with it needs a different approach. Pressurized release of high flash point industrial fluids, such as kerosene, has the potential to create a flammable aerosol. Pressure differential as low as few bars (Bowen and Shirvill, 1994) will suffice to ...
