Abstract (Summary)

Production stream in petroleum engineering is typically a mixture of oil, water, gas, and solid particles. The oil and gas industry, as the largest industry in the world, has been producing billions of gallons of produced wastewater every year.

Hydrocyclone, as a centrifugal separator for the produced water, has been widely used in oil and mineral industries because of their compactness and low operation cost. High costs of production of hydrocarbons, besides the environmental aspects of discharging wastewater, magnify the importance of research and development in wastewater treatment field.

Due to the complexity of the flow in hydrocyclones, there is no certain design of the most efficient hydrocyclone that assures high oil-water separation efficiency. Beside the field operational conditions, the dimensional ratios of hydrocyclone components play a significant role in their performance and separating efficiency.

Because of its effects on the split ratio of flow between outlets and tangential velocity, vortex finder configuration has an important role in increasing the separation efficiency. In this research, for the first time, the effect of using cone-shaped vortex finder has been investigated. Multiphase flow, liquid-liquid and solid-liquid separation were simulated using Computational Fluid Dynamics (CFD) and found that model 3 among 4 models, works the best.
