Vacuum Distillation Nozzles

Use of vacuum pressures to lower the boiling temperature of liquids to aid in separation of various components


Vacuum distillation is used by the petroleum and chemical industries to help separate individual components and compounds from bulk process streams. This process plays an important role in the refining process to separate hydrocarbon fractions without high temperatures that could damage the fractions and cause coking. Vacuum is employed to lower the boiling point of the sprayed liquid reducing the temperatures at which the more volatile elements will flash and reducing the energy/heat input required.

Spray nozzles are frequently used used to distribute the process fluids into the vacuum distillation units. Well atomized sprays produced by nozzles increase the exposed surface area of the process fluid and thereby increase the evaporation rate and separation efficiency. When packed columns are utilized in vacuum towers, where the gas side pressure drop must be low, spray nozzles also uniformly wet the packing, over which the gas flows and contacts the liquid.


Selecting a Vacuum Distillation Nozzle:

Important factors to consider: flow rate, spacing, uniformity, clog-resistance

  • Process vessel pressure, temperature, and fluid composition
  • Required material of construction for abrasive or corrosive environments
  • Required coverage
  • Potential for spray media flashing prior to nozzle orifice
  • Available / required flow rates
  • Available pressure drop (∆P) across the nozzle
    • ∆P = supply pressure at nozzle inlet - process pressure outside nozzle
    • Important to note where the process side is under vacuum
  • Our experienced engineers can help determine which nozzle will perform as required with your design details
