Schematic diagram of a typical hydrocyclone. Over the past two decades, the mini hydrocyclone (MHC, the main diameter Dc is less than 35 mm), also named micro or miniature hydrocyclone, gradually appeared and has gained more and more attention in the separation of fine or ultra-fine particles
Hydrocyclone G with an SC of 2.5 wt % provided the best classification performance (C f = 0.89 and C c = 0.99). With the increase in feed SC, the general separation performance of all hydrocyclones decreased, but the arc inlet hydrocyclones still exhibited relatively better performance than the tangential ones. If a higher feed SC is …

Multotec hydrocyclones are used around the world in mining and processing minerals, manufacturing, aggregates, food processing, wastewater management and other industries.
In a hydrocyclone, a slurry enters through a tangential inlet, giving rise to a vortex in the stationary body. The particles and fluid are accelerated centrifugally and separation occurs in the radial direction. Denser materials migrate to the outer wall of the hydrocyclone chamber, while less dense materials move toward the inner axis. ...
The dynamics of hydrocyclones is complex, because it is a multiphase flow problem that involves interaction between a discrete phase and multiple continuum phases. The performance of hydrocyclones is evaluated by using Computational Fluid Dynamics (CFD), and it is characterized by the pressure drop, split water ratio, and particle …
The hydrocyclone consists of a conical shaped vessel, joined to a cylindrical section, which has a tangential feed inlet. There are two axial product outlets, the spigot is situated at the apex of the conical part and the vortex finder is located at the upper end of the cylindrical section and contains a tube extending into the hydrocyclone,
hydrocyclone technology has been shown to provide extremely high throughput operation using an entirely passive design without the need for precise control over inlet flow rates to maintain high separation efficiency. For example, a commercial hydrocyclone with 125 mm chamber diameter operating at inlet pressures up to 124 kPa, corresponding to ...

A hydrocyclone with an oil collecting pipe was proposed to realize the rapid and efficient pre-separation of the produced fluid on the offshore platform. The effects of column diameter ratio, water phase outlet diameter, oil collector length, inlet flow velocity, inlet oil volume fraction and other parameters on the separation performance of ...
generated inside a hydrocyclone due to the tangential entry in-creases with decreasing cyclone diameter. The performance of an industrial hydrocyclone is generally controlled by using suit-able spigot diameters keeping other variables unchanged. Any change in spigot diameter will, therefore, change the pressure drop.
The hydrocyclone liner has a tangential inlet which creates a swirl within its core. This high velocity swirl action imparts massive centrifugal forces to separate the oil from the water, sending the two luids to their respective discharge ports. By utilising centrifugal pressure as the means of separation, the hydrocyclone
Abstract. This chapter gives a brief synopsis of hydrocyclones in theory and in practice, including basic design, characterization of performance, models, scale-up and …
The vast majority of current research on hydrocyclone field centrifugal separation focuses on low concentration fluids having volume fraction less than 3%. For high-concentration fluids having volume fractions greater than 10%, which are often encountered in engineering, the law governing particle motion and the classification …

The gas moves toward the center of the hydrocyclone with the oil and exits the unit through the reject port. A small amount of gas can improve performance, but too much gas disrupts the smooth flow of the oil core and bottlenecks the flow of oil out of the reject, Walsh said. Important trade-offs must be considered when designing a …
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.
The volume fraction of air in the hydrocyclone's core approaches one. The majority of the air fed into the hydrocyclone escapes through the overflow. As a result, air bubble …
Since the flow enters at the periphery and top of the hydrocyclone and leaves through the top and the bottom of the vessel at its center, there is a three-dimensional fluid motion, called vortex motion, with tangential, axial and radial velocities.The vortex motion produces a low-pressure zone in the center of the device that sucks air …

The results showed that the hydrocyclone preferably separates the particles that are >1 μm in the first 60 min. Later, the particles in the submicron range were increasingly discharged in the underflow. A simulation for the classification in a batch hydrocyclone with a closed circuit and underflow box is presented.

Hydrocyclone separator flow pattern complexity, changing hydrocyclone air core patterns, and unsteady flow have been discussed in previous studies. Large-eddy simulation (LES) has been used to simulate cyclone swirls [19,20,21]. LES is a dynamic simulation, and under the same structure and size, LES requires finer grid than any other …
Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the …
