Abstract
The de-emulsification of oil/water emulsion by means of electrocoagulation (EC) was investigated. The effects of operating parameters have been studied such as, initial oil concentrations, current densities, electrolyte concentrations (NaCl), gap between anode and cathode and the stirring rate. The best conditions among studied parameters are: Initial oil concentrations 250 ppm, current density 130A/m2, NaCl concentration 6g/l, gap 1.5cm and stirring rate 300 rpm. It was found that the Al electrode is preferred than Fe electrode at the same conditions. Double pair electrodes (Al-SS/Al-SS) give better results than single pair electrode (Al-SS). The effect of electromagnetic field had improved oil removal and energy consumption, where the percentage removal increases to 99.2% for Al-SS/Al-SS and 97% for Fe-SS/Fe-SS and reduces the energy consumption by 25% and 34.6% respectively.
