Effect of graphene oxide on demulsification process of heavy crude oil emulsion: article / Muhammad Faizal Sahak, Aqilah Dollah and Nur Hidayati Othman

Chemical demulsification is one of the famous method to separation of oil and water emulsion. The higher price of chemical used in the market industry create a potential study on the graphene oxide as a demulsifier. Recent study on Grapehne oxide show ability to act as efficient demulsifier. The abudance and cheap price can be problem solver to the emulsion problem. The synthesis of graphene oxide created from raw graphite that undergo strong oxidation based on Hummer method. The categorization of sample can be determine by using FTIR and XRD test. The test for the efficiency study of graphene oxide as demulsifier can be divided in two part which is bottle test and Interfacial tension. The demulsification process efficiency of added graphene oxide can yield in the range of 99.87% to 99.98%. The reason can be supported by the interfacial tension reduction with increasing concentration of graphene oxide.
