BETE nozzles are used worldwide in toxic gas mitigation spray systems to remove water-soluble, toxic gases from the air in an accidental leak. Nozzles prevent the spread of hazardous and poisonous vapor clouds into the atmosphere by producing a cloud of small droplets capable of capturing and containing the leak.
Chemical processing plants, refineries, and manufacturing facilities use and produce acidic or basic solutions, such as hydrofluoric acid (HF), hydrochloric acid (HCl), chlorine (Cl), or ammonia (NH3). These can produce toxic gas clouds if they are accidentally leaked or exposed to atmospheric conditions. Mitigating accidental releases of these gases can often be accomplished with water sprays with small average droplet sizes, maximizing the surface area to volume ratio and providing the greatest contact between the water and the toxic/corrosive gas.
Common Uses and Industries
- Containment and mitigation of toxic gas leaks with water spray systems
- Dousing leaks from ammonia tanks in the chemical industry
- Containing accidental release of HF, HCL, or CL gases
- Dispersion of LNG vapor clouds
- Towers and columns where absorption/mitigation is an integral part of the overall process stream
- Petrochemical Processing Industry
- Chemical Processing Industry

Important Factors to Consider When Selecting a Toxic Gas Mitigation Nozzle:
Size & shape of target object or area
Available nozzle mounting locations
Required droplet size for effective mitigation:
- In most applications, maximizing the surface area to volume ratio of the spray is the most important factor as this exposes the greatest amount of surface area
- As the absorption kinetics are primarily driven by surface area, this leads to more efficient capture of the gas by the liquid
Required flow rate for effective mitigation
Available pressure drop (∆P) across the nozzle:
- ∆P = supply pressure at nozzle inlet – process pressure outside nozzle
Required material for environment and chemical compatibility
As a nozzle manufacturer, BETE Fog Nozzle Inc. cannot assume responsibility for the design of life/safety systems
