Removal of oil from polymer-produced water by using flotation process ...
The objective of this study is to optimise the flotation process that separates crude oil and water from anionic polymer (GLP-100) via response surface methodology. Hence, a model was developed to describe the efficiency of oil removal under the influence of GLP-100 concentration, gas flowrate, and duration of flotation. Confirmatory experiments were performed to validate the model at a ...

New Eriez StackCell improves flotation cost and performance
Conventional flotation It is commonly appreciated that the flotation separation process depends on at least two sequential steps. In the first step, ore particles and bubbles collide efficiently to form aggregates. The second step occurs as these bubble-particle aggregates gently float to the top of the unit and join the froth phase.

The Use of the Jameson Cell to Improve Flotation Circuit Design
The Jameson Cell is a high intensity flotation cell in which pulp and air are brought together in a co-current descending flow in a vertical tube called the downcomer. The pulp is introduced into the downcomer through a slurry lens orifice to produce a high velocity jet that generates violent mixing and fine bubble size.
