Design and Simulation Analysis of Dewatering Hydrocyclones
In this paper, the objective was set to achieve 80% solid recovery in the underflow with a 45% solid concentration from a feed of 20% solid concentration according to dewatering purpose. This target was set to comparable to the plant requirement. The simulation was done for a 100TPH throughput hydrocyclone.However, simultaneous three-phase separation, which single conventional hydrocyclone cannot meet requirements, was required for degassing and desliming in oil recovery process, desliming and deoiling in oily water treatment, dewatering and desliming in drilling fluid recycling.

Thus, Ma et al. [17] designed a hydrocyclone of 100 mm in diameter for retaining the coke powder generated in refineries, which allowed attaining 99% efficiency in the recovery of 100 μm particles. The review by Yang et al.

The application of a hydrocyclone to recycle NGH and desand during NGH exploitation is a novel idea. The flow field and performance of this hydrocyclone is in the frontier of the research in this field and is unclear so far. This research aimed to reveal the flow field characteristics and performance of NGH downhole hydrocyclones. In this 26.3.2.3 Inline Cyclonic Separator. The hydrocyclone-based separator is a compact liquid-liquid separator. The unit consists of one or more axial flow cyclones with fixed swirl elements, as shown in Figure 26-19. The mixed oil-water flow enters the pipe spool via the inlet nozzle and moves into the inlet compartment.Hydrocyclone an overview ScienceDirect Topics

Design of novel hydrocyclone for improving fine particle
Hydrocyclone is a unit operation used for separating particles or droplets from liquid dispersion media. Because the feed suspension flows into a hydrocyclone rotationally, large particles are collected into the underflow due to the centrifugal effect generated by fluid rotational flow.

Hydrocyclone an overview ScienceDirect Topics
A hydrocyclone is a high-throughput gravity separation device used for separating slurry particles based on particle weight. For example, particles of similar size but different specific gravity, or particles of different size but identical specific gravity. Cyclones are also commonly used for dewatering of slurries given that they are much faster throughput recovery e ciency and sand removal e ciency with di erent inlet velocities by computational fluid simulations (CFD)-FLUENT software. The results show that the short circuit flow contributed to the hydrocyclone performance can be improved by increasing the inlet velocity.

Higher kaolin recovery with a water-injection cyclone
For a higher kaolin recovery, the underflow is usually further treated using a washing cyclone. This paper presents a new development in fine sand washing using water injection in the conical section of the classifying cyclone. The hydrocyclone control system is based on optical monitoring of the underflow. This monitoring makes the entireOn the other hand, due to the lowest solids recovery achieved by the mini-hydrocyclone VF3.2 S1.5, more fine particles report to the overflow, turning the underflow into a stream with a coarser PSD.
