EFFECT ON FOAM FRACTION DUE TO THE PRESENCE OF PARTICLES

In this section we present a sequence of short movies showing the performance of the bubble column reactor when no particles, hydrophobic particles and hydrophilic particles are used under the following conditions:

When particles are present, the following parameters apply:

Movie Menu:

Case 1: Foam in the bubble column reactor without particles

Case 2: Foam supression with hydrophilic particles

Case 3: Foam supression with hydrophobic particles

EFFECT ON FOAM FRACTION DUE TO THE FOLLOWING PARAMETERS:

Hydrophobic Particles Compared to Hydrophilic Particles

Particle Size

Volume Fraction

SUMMARY

The following figure compares the performance of the bubble column reactor when no particles, hydrophilic particles, and hydrophobic particles are used:

Hydrophobic particles are more effective in destroying foam than the hydrophilic particles.

We believe that hydrophobic particles suppress foam in the same way as hydrophilic particles, but in addition act to collapse the foam at the interface between the foam and bubbly mixture.
