چکیده

This study focused on their usefulness as a nano demulsifier. KIT-1 was characterized via FT-IR, XRD, SEM and Nonyl phenol ethoxylates (n = 6, 12 and 20 denoted as NPE-6, NPE-12 and NPE-20 respectively) surfactants were used with commercial demulsifier. The result showed that composition of KIT-1 and nonyl phenol ethoxylates (NPEs) in crude oil emulsion greatly improve the demulsification efficiency of the original demulsifier. It was found that the best demulsifier composition for breakdown of crude oil emulsion was the one based (NPE-12) and KIT-1. The results clearly showed that the sample with the best water separation performance would raise demulsification efficiency to a value of 95%.
