“…Hydrocyclone operates by fluid entering the cyclone tangentially via the inlet opening into the cylindrical section creating a swirling flow (vortex); the swirling flow generates a high centrifugal force required to separate the oil; therefore, higher density fluid (water) centrifuge to the wall of the cyclone whereas the lesser density fluid (oil) migrates towards the core of the cyclone. Hydrocyclone generally separate oil droplet size of 15µm and above from produced water, particles less than 15µm are difficult to separate using hydrocyclone as the separation efficiency of hydrocyclone decrease with particle size [3] Geometry and operating parameters have been used by many researchers in the optimization of hydrocyclone separation efficiency. Noroozi [4] used helical inlet to increase separation efficiency by 10% while increased inlet diameter as well was found to have also increased the separation efficiency of hydrocyclone [5] [6].…”

Hydrocyclone separate oil droplet size of 15µm and above from oil-water emulsion, particles less than 15µm are difficult to separate using hydrocyclone. The aim of this paper is to improve the separation efficiency of oil particles size of less than 10 µm in hydrocyclone. This paper evaluates the use of ferromagnetic particles for improving separation efficiency of droplet size less than 10μm in liquid-liquid hydrocyclone. Eulerian-Lagrangian model was used in conjunction with the Reynolds Stress Model (RSM) for turbulence and Magneto Hydrodynamic model (MHD) account for ferromagnetic particle conductivity. It was observed that use of magnetic particles increases separation efficiency by approximately 30% and 22% for 0.018% and 0.18% feed concentration respectively for particle size between 1-10µm and 32% increment was observed for particle size between 11-15µm. The increment is attributed greatly to the increase in density of oil as a result of doping micro-sized magnetic particles with oil-emulsion. Finally, it was seen that increasing magnetic field strength from 0.5 Telsa to 1.5 Telsa increases separation efficiency in the range of 1-4% and the use of magnetic particles increase the velocities of the fluid.

“…The first is called tangential or reversed flow cyclone and the other is axial cyclone (Nieuwstadt and Dirkzwager, 1995). In tangential flow cyclones, the flow is put into to the separator tangentially, which was first proposed in 1891 for the gas-liquid separation (Bai et al, 2011). The hydrocyclone and gas-liquid cylindrical cyclone (GLCC) are common tangential flow cyclones.…”

Gas-liquid separation technology is widely used in various fields of industrial production. In this research, a new kind of gas-liquid separator was proposed for the separation of gas-liquid mixture under different flow patterns. An inclined experimental system with an angle of 60 degrees from the vertical was established to test the new designed gas-liquid separator using of water and air as the working fluid. The experiment was conducted with the water flow rates covering 2.85-4.17 m 3 /h and the gas volume fraction covering 5-90%. Experiment results show that the separator can enable high efficient separation of gas-liquid mixtures under different patterns, especially under unstable flow patterns. The liquid level inside the separator is an important factor affecting the performance of the separator. On the basis of this, the critical liquid level of the separator was proposed for the practical application of the separator. This study fills the gap in the field of gas-liquid separation and provides a method for the separation of gas-liquid mixtures under different flow patterns.
