Demulsification optimization process on separation of water with heavy oil

A large amount of impurities in the oil when it is produced makes price decrease. Therefore, necessary to demulsify stable emulsion which not separated from oil, so that impurity level becomes low. For this reason, required add a demulsifier increase water separation higher. Demulsifier highly influenced by temperature, salt content, mixture, and time. In study result yields highest d NaCl 60%+PEG 1000 (20%), with heating system temperature at 70oC for 1440 minutes. The as much 96%.
