Condensate & Mixing Eductors

Principle of Operation of Condensate & Mixing Eductors

Fig. 242 Condensate and Mixing Eductors are designed to mix two liquids intimately in various proportions in operations where the pressure liquid is the greater proportion of the mixture. Typical applications include removal of condensate, mixing gasoline with acid, blending and proportioning chemical solutions, and diluting acids and alkali. In operation, the pressure liquid issues from the nozzle at high velocity and entrains the suction liquid. The extreme turbulence in the throat of the eductor mixes the two liquids, blending and emulsifying thoroughly and completely.

Figure 242 Condensate and Mixing Eductor is highly efficient and has a removable throat for abrasive services.

The Fig. 242 Condensate and Mixing Eductor is the most efficient of all the eductors because it is specially designed to the customer’s conditions.  The removable throat makes this eductor good for abrasive services since only the throat would need to be replaced in the event of excessive wear.

  • Introducing anti-knock agents and coloring additives into gasoline.
  • Removal of condensate in power industry.
  • Mixing hydrocarbons with caustic in power generation.
  • Blending chemical solutions.

This shows a typical proportioning system using a Fig. 242 Eductor. Rate of flow is measured by a Rotameter and is controlled by a valve in the line. A valve in the pressure line and orifice of the eductor nozzle control the flow of the pressure liquid. Fluids are thoroughly mixed in the desired proportions and are then discharged.
