Abstract

ABSTRACT ​ Crude oil is generally mixed with water at the time of production. The resulting water must be separated from the oil and properly resolved. The oil andwater mixture at the time of production is known as an emulsion. In addressing the problem of emulsions requires the additionof a chemical compound, commonly referred to as demulsifier to be able to separate water and oil. This research aims to make the formulation of demulsifier locally based on olive oil.this olive oil will be processed into a surfactant compound because it has a very high saturated fat content. The manufacture of this demulsifier using saponification methid is to heat the olive oil and add the KOH dissolved in aquades, as well as the added glycerin to taste. Then, the process of testing demulsification with a sample of the emulsion of crude oil that has been prepared using the bottle test method. Testing is conduced for 180 minutes and observation is made every 30 minutes using the waterbath. Local demulsifier made from olive oil materials is expected to overcomewater emulsion in oil better and environmentally friendly than commercial demulsifier. From the test result of several temperature conditions, different concentration and time obtained the best test results by demulsifier in the separation of water at a tempersture of 80℃ and concentrations of 5 ml. in sample 1 demulsifier surfactant (DS1) and the demulsifier surfactant (DSL1) added lemon separates the water by as much as 40 ml And 48 ml, sample 2 demulsifer surfactant (DS2) and the demulsifier surfactant (DSL2) added lemon separates as much as 38 ml and 43 ml, meanwhile, the commercial demulsifer separates the water by 39 ml.It can be concluded that the demulsifer made from olive oil can separate water effectively compared to the commercial demulsifier.
