Abstract
The crude oil had found in the depth of the earth and pumped out on land or in the seabed. Before being used as fuel or as a raw material in the petrochemical industry, crude oil is refined into different fractions separated into light and heavy fractions, which are then, converted into various products, such as petrol, diesel oil, or jet fuel. Usually, in the crude oil had presence of water which may cause a lot of problems due to transporting, operational problems and equipment corrosion. Therefore, this motivated many researchers to study the stabilization of crude oil emulsion since few years. Thus, the main aim of this study is to prepare of model emulsion which water in oil by prepared the sample first with continuous phase (crude oil) and emulsifier before added the dispersed phase. Then, the characteristic of the water in oil emulsion had study the stabilization via difference surfactants and their concentration for 20%-80% and 50%-50% water and crude oil ratio samples. However, the 20%-80% showed most stable compared to 50%-50%. Moreover, LSWR also had found as most stable as span 83, span 80 and triton x-100. The stable crude oil emulsion also had undergoes mechanism for characterize the affected of viscosity at varied temperature, rpm and concentration for crude oil and the aqueous phase. In this mechanism applied, the characteristic of crude oil and aqueous phase had showed the rose of temperature, rpm or concentration, the decreasing of viscosity. Then, the stable crude oil emulsion had evaluated the performance of de-emulsification via difference chemicals surfactant and their concentration at normal gravitational settling. The approximately 75% of water had separated at 24 to 96 hours had showed optimum and the best separation via Hexylamine. Hence, this study affords an efficient stabilization and separation only by using chemicals surfactants and concentration with the normal gravitational settling.
