Development work primarily at Southampton University, Thew (1986) has, however, succeeded in disproving this. By elongating the cone and using narrow angles as small as 1° to 2° the shear zone is minimized relative to the non shear inner zone and finely dispersed oil in water can be separated down to a few tens of ppm.

IMPROVING HYDROCYCLONE GEOMETRY FOR OIL/WATER .

Hydrocyclones use centrifugal fields to promote the separation of a disperse phase from a continuous phase. Hydrocyclones have advantages in comparison with others separation devices due to their low cost of manufacturing, installation, maintenance, and simple operation. The purpose of this work was to develop a hydrocyclone for water treatment of refinery streams with an oil mass fraction of 1%.

Dewatering Hydrocyclones

Dewatering Hydrocyclones

Dewatering hydrocyclones vary in size as they are required to perform a number of different tasks, and the appliion is more complex than standard deoilers due to the wide varying water:oil ratio. Feasible appliions can generally be classified as either water continuous (7090% water cut) or oil continuous (1030% water cut).

DeOiler: simple oil water separation

A tangential feed of oily water enters each cyclone through a unique involute inlet, where the solution begins to spin. As the mixture flows through each cyclone, it accelerates, increasing the centrifugal force and sending the lighter oil to the hydrocyclone's centre for removal through the overflow.
