Fluid dynamics of the water-oil separator system with water flow rate variations and oil 1, 2, 3 l/min

Abstract

Separation of immiscible liquids is a very useful technology that can be applied to various industrial and environmental problems, for example accidental oil spills at sea, offshore oil platforms and underwater oil fields, and waste oil spills. The multiphase separator was the first grounded equipment used to separate production liquids into gas, oil and water. Water-oil separator is a device used to separate water and oil. This study aims to apply the separation of water and oil, and analyzing fluid dynamics in a horizontal type water-oil separator system with two bulkheads. In this study, a test was conducted on a water-oil separator where the water and oil flows were separated with variations in the water flow rate: 1, 2, and 3 l/min, and the oil flow rate was constant at 1,2,3 l/min. The oil used is diesel fuel type Pertamina Dex which has a density of 820 Kg/m3 and a dynamic viscosity of 0.00164 Pa S. The test shows that the flow of water and oil has an effect on the efficiency of the separation of oil and water, the more the flow rate of water increases. and the flow rate of oil, the efficiency of oil and water separation tends to decrease, where the highest efficiency value is found in the flowrate of water 1 l/min and the flow rate of oil 3 l/min with a value of 94.1%, while the lowest efficiency value is found in the flow rate of water 3 l/min and flow rate of oil 3 l/min with a value of 90,2%.
