Development of hydrocyclonic separation is introduced first. The characteristics of the dynamic hydrocyclone are described. The laboratory study and oilfield tests of dynamic hydrocyclones were carried out. Some photos indicating flow phenomena inside the hydrocyclone were taken and analyzed for understanding the effect of some varieties on hydrocyclonic separation. Relations of flowrate, and o...

The hydrocyclone has a very important roll in industrial separation. The consideration of its behavior is very important for design. In this investigation, behavior of water flow and particles trajectory inside a hydrocyclone has been considered by means of numerical and experimental methods, and results have been compared together. To have a numerical simulation, a CFD software was used, and f...

Due to the importance of material classification issue in grinding circuits, the ‎performance of primary and secondary hydrocyclones in grinding circuit of Esfordi ‎phosphate plant was investigated by sampling within 7 days from feed, overflow, and ‎underflow‎ of these hydrocyclones. At first, the d80 of above streams samples were calculated by ‎the screening analysis. The results showed ‎that ...

This paper is devoted and intended to solve the problems of determining the precise separation efficiency and accurate prediction for the solid yield of multi-product cyclones based on existing experimental data. The influence of inlet pressure control on separation performance of multi-product cyclones is investigated. Hydrocyclone separation performance is influenced by many factors such as t...

The procedure usually employed for specifying a set of hydrocyclones used in Newtonian fluidsolid separation processes can be extended to the case of non-Newtonian fluids. The apparent viscosity, μapp, is the link between the two cases, and can be evaluated from the knowledge of the shear stress function, S, and the characteristic rate of shear, λ*. In order to verify the validity of this, expe...

Abstract The treatment of transformer oil wastewater in the accident pond with ozone has no secondary pollution to environment. cavitation technique was used enhance oxygenation process and hydrocyclone separator do pretreatment. After sewage enters hydrocyclone, separation efficiency reached up 60%, which reduces processing load subsequent device. Through 10min cycle a device, concentration im...

The conventional oil recovery system in the Fushun oil shale retorting plant has a low oil recovery rate. A large quantity of fresh water is used in the system, thereby consuming a considerable amount of water and energy, as well as polluting the environment. This study aims to develop a closed process of shale oil recovery from the circulating washing water for the Fushun oil shale retorting p...

Hydrocyclone with guide vanes is one type of swirl flow launching device without energy input. For researching the characteristics that hydrocyclone, distribution sections and their variation along were studied using numerical simulation physical experiment. In addition, field was convenient to be divided into three-dimensional velocities: axial velocity, circumferential radial velocity static ...

Large Eddy Simulations of the flow through a hydrocyclone are used to demonstrate that the Grid Convergence Index (GCI) is a practical method of accounting for numerical uncertainty. The small values of GCI (<7.2%) associated with the tangential velocity predictions suggest that numerical uncertainty due to discretization error does not greatly contribute to the disagreement between simulation ...
