The hydrocyclone designed has provided total efficiency of E T = 93% with a small flow ratio of R F = 7% which implied reduced total efficiency being E′ T ≅ E T = 93%. It can be noted that for an inlet stream with 40% oil-in-water concentration, the overflow and underflow oil concentrations are 89% and 4% respectively, which shows the high ...

The hydrocyclone was numerically simulated by varying the length of the oil collection pipe. Other geometric parameters remained changed when changing L. The inlet flow rate was 0.5 m/s, and the inlet oil volume fraction was 10 %. The lengths of the oil collecting pipe to be simulated were 150, 170, 190, 210, and 230 mm, respectively. ...

To summarise, a hydrocyclone separates particles using the generated centrifugal forces. This centrifugal force is generated because the liquid enters the cyclone tangentially at high speed and is accelerated by a conical middle section. This helps to create a liquid vortex in the cyclone. The smaller the diameter of the cyclone, the greater ...

Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone.

The gas moves toward the center of the hydrocyclone with the oil and exits the unit through the reject port. A small amount of gas can improve performance, but too much gas disrupts the smooth flow of the oil core and bottlenecks the flow of oil out of the reject, Walsh said. Important trade-offs must be considered when designing a …

The hydrocyclone was operated with an air-core at varying underflow. Kelsall found that the tangential velocity increased from the hydrocyclone wall towards the center, reached a maximum value and then rapidly decreased (Fig. 9). The maximum value was located at a radius that was similar to that of the hydrocyclone wall.
