Application of Gas-assisted Solvent Flotation Technique on Oil-field Polymer-bearing Produced water

摘要：

　　The solvent flotation technique adopts organic solvent with low volatility as the second liquid phase, which could dissolve the components including emulsified crude oil, surfactant in the water.The modification of pH value, ion intensity, temperature, speed of air flow, and species of solvent could improve the efficiency of the flotation.The proposed method has been successfully applied to produced water treatment, the pharmaceutical industry sewage disposal and so on.It also has potential usage in sewage disposal of offshore oil field.
