Demulsification optimization process on separation of water with heavy oil

Abstract

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