“…According to the literature, the hydrocyclone has demonstrated great efficiency in the free oil/water separation process [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. This equipment has a high processing capacity, requires little physical space for installation, is simple to operate, and requires low maintenance frequency.…”

“…In this sense, some studies using filtering hydrocyclones have been reported in the literature [ 33 , 34 , 35 , 36 ], in general applied in the mineral sector (solid–liquid separation), and there is little research related to the process of separating water contaminated by oil (liquid–liquid) [ 6 , 7 , 8 , 14 , 30 , 37 , 38 ].…”

This research aims to study the process of separating water contaminated with oil using a hydrocyclone with a porous wall (membrane), containing two tangential inlets and two concentric outlets (concentrate and permeate), at the base of the equipment. For the study, the computational fluid dynamics technique was used in a Eulerian–Eulerian approach to solve the mass and linear momentum conservation equations and the turbulence model. The effects of the concentration polarization layer thickness and membrane rejection coefficient on the permeate flow, hydrodynamic behavior of the fluids inside the hydrocyclone, and equipment performance were evaluated. Results of the velocity, transmembrane pressure and oil concentration profiles along the equipment, and hydrocyclone performance are presented and analyzed. The results confirmed the effect of the membrane rejection coefficient on the equipment performance and the high potential of the hydrocyclone with a porous wall to be used in the oil–water mixture separation.

“…In general, it is difficult to achieve demulsification and dewatering of emulsion efficiently by using a single processing method (Liu and Wang 2016;Jung et al2019;Hamza et al 2020;Qiu et al 2020;Gong et al 2018). The demulsification and dewatering can be well achieved by using various processing methods or by coupling an integrated unit operation, which is also the key direction of future development (Eow and Ghadiri 2002;Vashahi et al 2019;Xu et al 2020;Motin and Bénard 2017).…”

The demulsification and dewatering of the W/O emulsion are widely used in petrochemical industry, oilfield exploitation, and resource and environmental engineering. However, efficiently treating emulsion via traditional single methods. In this study, a new double-field coupling demulsification and dewatering device is proposed, where the conical structure of the device is double spherical tangential type. The numerical model for double-field coupling is established, especially, the population balance model (PBM) is used to simulate the coalescence and breakup of dispersed droplets under the double-field coupling action. And the effects of three conical structures on the internal flow and separation efficiency are analyzed. Results show that the conical structure has a significant effect on the coalescence of droplets, especially the double spherical tangential cone is more conducive for improving the coalescence ability of small droplets and improving the separation efficiency of the device. After optimization, the optimal R value of the double spherical tangential coupling device is 300 mm, and the separation efficiency can be up to 96.32%, which is 6.13% higher than the separation efficiency of the straight double-cone coupling device.

“…Various processes like particle classification 1, product purification 2, water deoiling 3, suspension concentration 4, and solid separation 5 benefit from hydrocyclones. Unlike centrifuges, hydrocyclones have the capability to separate particles in continuous processes 6 while this equipment has no movable part, thus saving maintenance cost.…”

Numerical and Experimental Biomass Separation from Fermentation Process by Minihydrocyclones

Biomass particle separation is challenging in the pharmaceutical industry because of the smallness and lightness of such particles. Centrifugation is applied conventionally for batch separation. However, imposing multiple wash steps in order to eliminate culture residues and the high risk of extrinsic contamination hamper batch techniques. In this research, minihydrocyclones were introduced to provide a better solution for the mentioned limitations in continuous processes. Numerical separation of methylotrophic yeast from fermentation broth was carried out in three hydrocyclones with different lengths, and the most efficient one was examined experimentally. Three various feed flow rates and seven feed concentrations were evaluated. The concentration of biomass suspension in the product was raised to 20 %.
