Application

... Hydro cyclones (Hydraulic cyclone) are widely used as filter separators in many fields such as the mineral, petroleum, food and Agriculture industries and etc. The specific features of hydro cyclones such as low maintenance costs, easy operation and installation, and no moving parts, make them appropriate for separation processes. Some of the applications of hydro cyclones in petroleum industries are liquid-liquid (Deoiling), gas-liquid (Degassing), solid-gas (cyclones), solid-liquid and solid-gas-liquid (Desanding and Desilting) separators. Each of these applications and based on the existed process conditions have their special design. Hydro cyclone and multi-hydro cyclones have the same theory and practice, but with this difference that multi-hydro cyclones provide better efficiency by using smaller and more hydro cyclones.

Theory

...

The hydro cyclone (or cyclone) is a piece of equipment which utilizes fluid pressure energy to create rotational fluid motion. This rotational motion causes relative movement of materials suspended in the fluid thus permitting separation of these materials, one from another or from the fluid. The rotation is produced by tangential injection of the fluid into a vessel. Hydro cyclone are often including several parts which are: inlet (it could be simple, helical, Single-entry and multiple-entry and …), main body (cylinder-cylinder, cylinder-cone and cylinder-cone-cone which the angle of cone acc. to required spec is selected), and vortex finder (cylindrical part for overflow).

Mechanism

... The mechanism of hydro cyclone is based on the principle of centrifugal force causing the separation of heavy phase from light phase by the differences in density and particle size. As the fluid is injected to hydro cyclone tangentially, it moves downward and near the wall but gradually and because of pressure loss, light phase is driven to center and upward to exit from overflow; heavy phase maintains its downward and near wall moving to exit from under flow.

What we do

Saban Sanat Sepahan by using updated world sciences and related software, has the ability of designing, engineering and manufacturing of hydrocyclone in different applications. The related experts after receiving the required conditions and spec, design the suitable equipment by Saban designer program and validate its performance by using simulations software.
