| Abstract | ||
| Emulsion breaking is one of complex process used in many practical applications such as the petroleum industry, painting and waste-water treatment in environmental technology. Chemical demulsification is the most widely resolved method of treating water-in-crude oil emulsions and involves the addition of chemical reagents to destroy the protective action of emulsifying agents and allow accelerating the emulsion breaking process. Our experimental results showed that, the addition of glycols chemicals as a cosolvents like ethylene glycol methyl ether (EGME), monoethylene glycol (MEG), polyethylene glycol (PEG-1500), in combination with commercial demulsifier RP-6000 will enhancing the process of emulsion demulsification. The demulsification experiments were carried out at controlled temperature 65oC and screened by bottle test using about 100 ppm demulsifier doses. The maximum amount of water separated after 120 min found to be 87.7% for (75/25) (RP6000/PEG1500) .Where, the water separations for (75/25) (RP6000/MEG) and (75/25) (RP6000/EGME) for demulsifier were 71% and 65.2% respectively. | ||
