separation method for hydrocyclone

US5667686A - Hydrocyclone for liquid - liquid separation ...

A liquid--liquid separating hydrocyclone that utilizes gradual taper angles to reduce energy loss, helical precession, and velocity differentials and, thereby, increase the efficiency and capacity of the hydrocyclone. A separation portion of the hydrocyclone tapers to the underflow outlet orifice and no cylindrical portion is used at the underflow end.

Separation of yeast from alcoholic fermentation in small ...

Mar 05, 2012  This separation process is a challenge because the yeast is small and low density. Thus, the hydrocyclone is an interesting alternative because it uses the same principle of centrifugal separation, requires low maintenance and can be readily sterilized. This work aimed to study the separation process of yeast from fermentation using hydrocyclones.

Hydrocyclones - an overview ScienceDirect Topics

Hydrocyclones, otherwise known as centrifugal cleaners, vortex cleaners, or centricleaners, came into widespread use in the paper industry in the 1950s.Prior to this, hydrocyclones were commonly used in the mining industry for separations. A hydrocyclone consists of a cylindrical-conical vessel with the inlet flow introduced tangentially at the top (Figure 8).
