INJECTION WATER TREATMENT
Liquid cyclones have been effectively used for de-oiling
applications for many years. The cyclone is a simple device, which
causes the centripetal separation of materials in a fluid stream. That
fluid stream can be either a liquid or a gas.
On entering the cyclone tangentially, the fluid begins to spin. This
creates a radial force that directs the heavier phase towards the
edges of the cyclone. The heavier phase then passes out of the cyclone
underflow due to the lower pressure at the underflow compared to the
inlet. The less dense phase is concentrated in the centre of the
cyclone before passing out of the cyclone overflow due to the even
lower pressure at the overflow than the underflow.
Unlike the slow setting within a settling or skim tank, the cyclone
separator system yields fast separation and utilises less space.
Separations occur quickly because one 'g' of gravitation force is
replaced by many 'g's of radial force.
