Post Mixing Optimization and Solutions


This is a continuation of the Process Intensifier - Optimization with CFD: Part 1 paper.

Using the power numbers and the usual power number correlation, the amount of power required by the impellers for each unit is:

Table 2: Power consumptions in HP (kW) at N=1750 RPM and water. The size of the motor is estimated in horsepower.

The power draw of the Process Intensifiers with axial impellers is about an order of magnitude less than the two designs with radial impellers. The size of the motor is an indicator of the cost of each unit. A 0.5 HP unit will be less costly than a 10 HP unit. Just the same, it is amazing that any of these small units can agitate up to 1.584 Million Gallons (6 Million Liters) per day (at 1100 GPM (250 m3/hr)).
