Abstract
AbstractLaboratory studies were conducted to determine the factors governing flotation-cell performance. It was learned that oil removal is increased by increasing collision and attachment efficiencies and gas/liquid contact time. Collision efficiency is increased by increasing oil-drop size and gas concentration and by decreasing gas-bubble size. Several factors (crude type, pH, temperature, etc.) were found to change attachment efficiency. No correlation between basic system properties and attachment efficiency was found.Some of these important parameters are determined by the cell design, whereas others are characteristics of the feed. Thus, the same type (design) cell will produce different effluent oil concentrations for different feeds. Also, the effluent from a given cell will change when the feed characteristics change.
