Based on the conventional hydrocyclone, a new type of cyclone—using guide vanes—is proposed (Zhen-bo et al., 2011), which is a reverse flow separator. Except for this separator, most axial inlet cyclones are straight through cyclones (Shi et al., 2012; Hamza et al., 2020). In these cases, the types of swirlers that produce swirling flow ...

Hydrocyclone performance may be measured differently depending on the application, but in all instances, cyclone performance is influenced by six factors. Hydrocyclones, also simply called "Cyclones", separate particles according to size and/or density using centrifugal force to accelerate the settling rate of solid particles.
hydrocyclone based liquid-liquid separation processes have only been accepted within the last 10 years.
