Emulsion Treatment using Local Demulsifier from Palm Oil

: Conventional demulsifier (chemical) are still used until now in many of oil industries which the formulas are both expensive and harmful for the environment.In this research, the new formula of local demulsifier will be tested with palm oil, lemon, glycerin, and KOH as the materials. Those materials are more friendly for the environment and contain hexane group and octadecenoic acid that are composition in plant that can break the emulsion. Crude oil (20 . 8 ◦ API) is taken from wellhead of the X Field in Riau, Indonesia. Emulsion sample will be treated with formula local demulsifier and tasted in water bath for 3 hours vulnerable with 30 minutes of observation. Bottle test method will be used with the following of 40 ◦ C, 60 ◦ C, and 80 ◦ C as temperature test.The test revealed that the formula demulsifier + lemon (DKL) given the best result than conventional demulsifier within 120 – 180 minutes at 80 ◦ C that separated 39 ml of water with 5 ml of concentration.P-value of temperature is the only less than the significance value ( α =0.05) means that the linear regression model meet the criteria of linearity and the changes that occur are significant.
