“…Hydrocyclones perform solid-liquid or liquid-liquid separation using a centrifugal sedimentation as a basic principle of separation [2]. In contrast to centrifugation which uses the same principle of separation, hydrocyclones have no moving parts, thus reducing the costs of acquisition, maintenance, and operation because they are considered as simple and easy constructions [3].…”

“…Among these studies, changes in hydrocyclones are reported in order to meet the individual needs of each industrial process. These modifications can be done by creating nonconventional equipment, either by changing the hydrocyclone geometry or by adding another unit operation to the process of hydrocycloning, or by any other change that differs from the hydrocyclone model first proposed [2,[8][9][10][11][12][13].…”

Hydrocyclones are designed for solid-liquid separation widely used in industry due to their advantages including high separation efficiency. Depending on the purpose desired by the user, it is possible to enhance the performance of the hydrocyclone through the combined use of other unit operations with the hydrocycloning such as filtration. The incorporation effect of a porous cylinder on a hydrocyclone with optimized geometry was studied experimentally. According to the main results, the filtering cylindrical hydrocyclone showed significant average reductions in energy consumption compared to conventional hydrocyclones of the same geometry. Minor differences in terms of total efficiency of the filtering equipment were observed compared to the conventional one.

： Downhole oil-water separator is the most important component of downhole oil-water separation system. Its structure has great effects on oil concentration of underflow (OCU) thus requiring further optimization. This work aims to propose an optimization method for the structural optimization of downhole oil-water separator that consists of two series de-oiling hydrocyclones. Firstly, the significant factors influencing OCU are identified by two-level Plackett-Burman Design (PBD) with twelve factors. Then the central levels of the five significant factors identified from PBD are determined by steepest ascent design. Secondly, response surface methodology (RSM) is used to establish the second order model between the OCU and five significant factors for the implementation of particle swarm optimization (PSO). Finally, the optimal structural parameters are obtained by PSO algorithm. Computational fluid dynamics (CFD) is employed to calculate the OCU for each particular case and analyze the separation performance variations before and after optimization. The simulation results show that compared with the original geometry and the best geometry in CCF design, the OCU of the optimized decreases. And the separation performance of the optimized geometry is remarkably improved for the oil droplets whose particle sizes are smaller than 35.78μm. Furthermore, laboratory experiments have been conducted to validate the proposed optimization method. The experimental results confirm that the OCU also reduces following the proposed optimization method. It can be summarized that PSO algorithm combined with PBD, steepest ascent design and RSM can be an effective method for the structural optimization of the downhole oil-water separator.

“…The experimental variables include the operation parameters and structure parameters of the hydrocyclone with feed solid, inlet pressure, diameter of the apex, and diameter of the vortex. Simultaneously, the method can be also used to arrange the experiment combined with the other technology in optimization [17]. Clearly, the experimental design method has good effectiveness to the optimization for the small number of tests and lesser test time and costs; however, due to the large amount of the impact factors, especially the structure factors involved in the hydrocyclone, only a few key factors can be selected and be optimized, and, also due to the amount of experimental works and because it costs too much, the DOE method is restricted.…”

To achieve efficient separation of calcium hydroxide and impurities in carbide slag by using hydrocyclone, the physical granularity property of carbide slag, hydrocyclone operation parameters for slurry concentration, and the slurry velocity inlet are designed to be optimized. The optimization methods are combined with the Design of Experiment (DOE) method and the Computational Fluid Dynamics (CFD) method. Based on Design Expert software, the central composite design (CCD) with three factors and five levels amounting to five groups of 20 test responses was constructed, and the experiments were performed by numerical simulation software FLUENT. Through the analysis of variance deduced from numerical simulation experiment results, the regression equations of pressure drop, overflow concentration, purity, and separation efficiencies of two solid phases were, respectively, obtained. The influences of factors were analyzed by the responses, respectively. Finally, optimized results were obtained by the multiobjective optimization method through the Design Expert software. Based on the optimized conditions, the validation test by numerical simulation and separation experiment were separately proceeded. The results proved that the combined method could be efficiently used in studying the hydrocyclone and it has a good performance in application engineering.
