Two-Phase Spray Media Nozzles

Inject and distribute fluid spray media that consist of more than one phase (vapor and liquid)

Questions? Ask an Engineer

Two-phase fluids can occur naturally in a process, as a liquid flashes into a vapor due to pressure or temperature, or they can be created when a gas or vapor is forced into the spray media process stream to help improve atomization of the spray media or other potential affects.

Two-phase media can significantly affect the flow rate and spray pattern of spray nozzles from their rated characteristics. In addition, these applications often carry with them additional criteria for nozzle selection, such as withstanding cryogenic or extremely hot temperatures, pressure variations, or withstanding corrosion and erosion. Due to the complex nature of two-phase flow application, some spray nozzles designs are better equipped than others to handle the spray media being in both liquid and gaseous form simultaneously depending on the vapor percentage present.
 

Selecting a Two-Phase Fluids Nozzle:

Important factors to consider:

  • Spray media vapor percentage
  • Process pipe/vessel pressure, temperature, and fluid composition
  • Required material of construction for abrasive or corrosive environments
  • Required coverage
  • Available/required flow rates
  • Available pressure drop (∆P) across the nozzle
    • ∆P = supply pressure at nozzle inlet - process pressure outside nozzle
  • Our experienced engineers can help determine which nozzle will perform as required with your design details


Common Two-Phase Fluids Nozzle Uses and Industries:

  • High temperature injection;
    • Spray nozzles operating at temperatures near or above the spray media boiling points may cause the injected fluid to flash and exist in two phases
  • Low pressure applications
    • Systems operating under vacuum can lower the spray media boiling point, which can cause the injected fluid to flash and exist in two phases
  • Hydrocarbon Injection
    • Hydrocarbons often exist in a two-phase form, especially in injection applications where control valves can create favorable conditions for production of multi-phase process flows.
  • Liquid nitrogen injection
    • Low boiling temperature of this spray media may lead to flashing prior to reaching the nozzle orifice
  • Air-water mixtures
    • Air or other gases are injected into the supply stream in order to increase atomization of the fluid as it is sprayed
    • Snow making
    • Dust control

MaxiPass

  • BETE's unique, clog resistant S-vane design gives the MaxiPass the largest free passage available for a given flow rate, making it resistant to clogging, efficient, and reliable
