Abstract (Summary)

The produced water is the highest volume liquid waste stream generated in the petroleum industry. There are different techniques for produced water treatment, such as oil-water separation. United States Environmental Protection Agency (USEPA) set the permitted maximum limit for the existing oil and grease in the treated produced water.

Hydrocyclone is one of the most common and effective devices in oil and gas industry for oil-water separation. The separation in hydrocyclone is based on the difference of the density of the oil and water. This treatment system not only can separate oil and water but also system removes all particles. At this stage, the hydrocyclone overflow can convey to flotation units and polishing system.

The Hsieh laboratory model of the hydrocyclone was simulated by Computational Fluid Dynamics (CFD) to study the behavior of flow inside the hydrocyclone and to evaluate the efficiency of the oil-water and solids separation. The comparison of the results of the simulation showed a good agreement with experimental data of Hsieh's model. The separation of oil droplets with different sizes was also investigated. This study also focused on the dimensionless groups at different vertical levels of the hydrocyclone, Gas Chromatography-Mass Spectroscopy and Turner TD-500D units as methods of measuring the concentration of oil in water.
