Chemical Injection Nozzles: Inhibitor (Corrosion/Scale Prevention)

Inject inhibitors into process piping or vessels to prevent corrosion and scale

Questions? Ask an Engineer

Many systems and processes can suffer from performance issues related to corrosion and/or scale buildup in various components such as piping, heat exchangers, pumps, valves, etc. Corrosion can affect the safety and mechanical integrity of a system by degrading materials and components. Scale build-up can affect the efficiency of a process by decreasing flow passages and potentially blocking all or part of a process stream. Heavy scale buildup has the potential to break off and clog or damage downstream equipment.

Compared to open-ended injection quills, BETE spray nozzles are designed to maximize efficiency in inhibitor injection applications as they atomize and distribute the inhibitor liquid into the process stream or vessel which increases the coverage and reaction surface area that reacts with chemicals and compounds in the process that may cause corrosion or scale formation. Spray nozzles coupled with BETE injection lances can distribute the inhibitors as evenly as possible along the center line of process streams or vessels.
 

Selecting a Corrosion/Scale Inhibitor Nozzle:

Important factors to consider:

  • Inhibitor density and viscosity
  • Process pipe/vessel size, velocity, pressure, temperature, and fluid composition
  • Available installation ports and required clearance diameters
    • In general process piping applications, a minimum of 3-5 pipe diameters of straight length upstream and 5-10 pipe diameters of straight length downstream are recommended to ensure spray dispersion
  • Required materials of construction for corrosive environments
  • Ease of maintenance/replacement
    • Retractable lances allow for quill/lance removal while leaving the process online
  • Required inhibitor flow rate
  • Available pressure drop (∆P) across the nozzle
    • ∆P = supply pressure at nozzle inlet - process pressure outside nozzle
  • Availability of steam, compressed air, nitrogen, or other carrier/atomization gases
  • Our experienced engineers can help determine which nozzle will perform as required with your design details
