Mists/spray releases

Release of liquids (as mists or sprays), of vapour or of dusts may be reduced in some cases by... 

Aerosols are also a form of a mist characterized by highly respirable, minute liquid particles. They can be formed by atomizing, spraying, or mixing, or by violent chemical reactions, evolution of gas from a liquid, or escape of a dissolved gas when pressure is released. 

Spray and mists releases generally behave like a gas or vapor release. The fuel is highly atomized and mixed with air. Sprays or mists can easily be ignited, even below the flash point temperature of the material involved, since mixing of the fuel with the air has already occurred. 

Sprays and Mists Medium sized releases of moderate frequencies that are mixed immediately in to air upon release. Typically pipe gasket, pump seal and valve stem failures under high pressure. On occasion releases occur from flare stacks. 

Three methods of applying atomized liquids were tested—by aerosols, by mist blowers, and by airplane. Sprays were released by the first two methods in buildings and by all three methods in the field. 

Control Spray fruit trees with dormant oil to kill overwintering eggs in garden or greenhouse rinse plants with water and mist daily to suppress reproduction of mites release predatory mites Metaseiulus occiden-talis on fruit trees, Phytoseiulus persimilis or similar species on vegetables, strawberries, and flowers spray insecticidal soap, pyrethrin, or neem as a last resort, spray infested plants with avermectins. 

EXPLOSION and FIRE CONCERNS combustible NFPA rating Health 3, Flammability 2, Reactivity 0 moderately flammable when exposed to heat, flames (sparks), or powerful oxidizers contact with active metals, strong caustics, or with strong oxidizers may cause fires and explosions toxic gases and vapors, such as hydrogen chloride, phosgene, and carbon monoxide may be released in a fire use water (as a blanket), spray, mist, dry chemical, foam, or carbon dioxide for firefighting purposes. 

A water-based solution of release agent is sprayed on the open HPDC die before closing it. This allows cooling and coating of the die. Some simple process measures allow the minimisation of the release agent and water consumption. These will also prevent the formation of a mist. These measures are ... 

The spraying of a water-based release agent on HPDC dies generates a mist with low concentrations of decomposition products. The mist is collected using a suction hood and an EP. 

In another technique, molten urea is sprayed at 148 °C onto cascading seed granules (<0.5 mm) in a rotating drum until they grow into product sized particles (2-3 mm). Heat released by the solidifying melt is removed primarily by evaporation of a fine mist of water sprayed into air that is passed through the granulation drum (Shirley, Nunelly and Cartney, 1982). 

Contaminated air from the fume hood enters the unit and passes through the packed hed, hquid spray section, and mist eliminator, and then into the exhaust system for release up the stack. The air and the scrubbing liquor pass in a...
