The flooded core solid-liquid hydrocyclone, termed a desander, is used extensively in the oil and gas industry to separate sand and solids from produced water. A desander comprises a standard solid-liquid hydrocyclone with an accumulation chamber connected to the apex. The accumulation chamber prevents formation of an air core. Thus, the ...

Hydrocyclone is a simple, low-cost equipment widely employed for separating aqueous particles by using a swirling flow field [14]. However, the separation cut-off of industrial hydrocyclones is generally above 3 μm [15], much larger than the size of colloidal particles (i.e., 0.001–1 μm) commonly present in water and wastewater.

This work evaluates the performance of commercial hydrocyclone for removing contaminant larger particles (silt fraction) in bentonite clays, which improves its commercial value. A steady-state Eulerian-Eulerian 14-phases CFD model was verified with experimental data. The model was further used to simulate the effect of geometry and operational conditions on the recovery …

In this study, a three-level Box–Behnken factorial design combined with response surface methodology for modeling and optimizing of operation parameters of hydrocyclones, namely feed solid, inlet pressure, vortex diameter and apex diameter, to produce three group bentonite concentrates was developed. In order to produce bentonite concentrates, …

After hydrocyclone separation the CEC increased by 138%, the FSV by 194% and AV by 325% in the bentonites, which in their natural state are not suitable for industrial use.Additionally, this study ...

A decoking hydrocyclone with a cone angle of 15° and an inlet size of 4 × 6 mm is the optimum hydrocyclone and the recovery efficiency of coke powders is stable at more than 90%.

The purpose of the hydrocyclone treatment was the removal of impurities from the raw bentonite sample and was carried out in a laboratory scale Mozley C 750 type hydrocyclone 5 cm in diameter. A detailed description of the experimental setup can be seen in refs. (Özgen et al. 2009; Boylu et al. 2010; Boylu et al. 2012).
