On-Line Sensor for Measuring Gas Velocities in Laboratory-Scale ...

Gas velocity (Jg) measurements conducted close to the froth-pulp interface over the cross-section of a flotation cell reveal how efficiently the incoming air is being dispersed throughout the volume of the cell. Furthermore, measurements of Jg at deepest locations in the cell provide valuable information about air recirculation and dispersion conditions in the bulk volume of the cell.

A flotation cell is the primary unit operation used to recover fine oil droplets from produced water systems. Both mechanical induced gas flotation (IGF) and hydraulic dissolved gas flotation (DGF) cells have been used for residual oil removal from produced water since the late 1960's (Sport 1970; Bassett 1971).

1 Froth Flotation - Fundamental Principles

Once the particles are rendered hydrophobic, they must be brought in contact with gas bubbles so that the bubbles can attach to the surface. If the bubbles and surfaces never come in contact, then no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5.

Pulp and froth phases in gas processing - PACE

Gas hold-up is the volume of the gas in the pulp zone of a flotation cell. The volume of gas reduces the pulp volume and therefore decreases the residence time available for flotation. The gas hold-up depends on the amount of air added to the flotation cell and is a strong function of pulp viscosity.
