ABSTRACT:
A process to mitigate or "knockdown" a hydroscopic chemical aerosol cloud released to atmosphere from a pressurized vessel by utilizing a pressurized gas and water spray to provide water droplets having a mean volume diameter (MVD) in a median range between 150-350 microns. The pressurized water spray is directed onto the chemical aerosol cloud at a volume rate of at least five parts of water to one part of the hydroscopic chemical to obtain a maximum fallout rate within a minimal travel range.
