How does a hydrocyclone work? Solids and water are pumped in under pressure, creating a swirling motion inside the cyclone cylinder which throws the solids to the outside of the cylinder by centrifugal force. The larger particles move downwards under gravity and leave via the bottom outlet with a small quantity of water. A small amount of …
To fix this, increase the density of solids feeding the hydrocyclone, or decrease the size of the apex. The apex will be the fastest wearing part of most units. When the apex wears out, the opening gets larger, therefore allowing more water to go out the underflow. To fix this, replace the apex with a new one.
A rotary hydrocyclone was developed for the treatment of the produced oily water on offshore platforms. The main advantages of this type of equipment consist in: a few second residence time resulting in a dramatic reduction in weight and volume; higher efficiency when comparing with conventional settling tanks or static cyclones; insensitivity to the …

The oil–water mixture passes through the hydrocyclone from bottom to top, most of the water comes out from the water phase outlet, and most of the white oil comes out from the oil phase outlet. Separation performance was investigated with the flow rate at inlet and volume fraction of oil at inlet as variables. Fig. 3.

Deoiling Hydrocyclones. Hydrocyclone based process systems are the most cost-effective solution for produced water treatment clean up. Located directly downstream on the water outlet of the production separator and upstream of the water level control valve, these systems operate in a proportional "pressure ratio" control manner.

For instance, to enhance the oil-water separation in hydrocyclones, Bai et al. [88], [172] utilized an air-liquid mixing pump to produce 15–60 μm air bubbles and provide high probability for oil-bubble interaction. After air bubbles with larger diameter, which could decrease the separation efficiency, were separated using an air-liquid ...
Hydrocyclone is a simple and efficient oil-water separator with no moving parts. It works on the principle of density difference to remove oil droplets from water/wastewater using centrifugal force. A hydrocyclone comprises three main parts – a cylindrical feed, an overflow with a vortex finder, and a conical component with an apex.

Separation methods based on the oil/water density differential (e.g., settling, flotation, hydrocyclone) require an exceedingly long retention time for the removal of emulsified oil, while chemical treatment (e.g., fentone process, coagulation) may not effectively de-stabilize oil-in-water emulsions particularly when the emulsified oil is ...

Hydrocyclone oil water separator is a skid-mounted packaged solution. It is a simple and most powerful oil water separator that does not use consumables or chemicals. In this separator oily water is pumped tangentially into the separator using a high-pressure low shear pump, it forms a powerful vortex and a huge centrifugal force.
Hydrocyclone is used to separate particles from produced water. It can be used in different industries, including oil and gas, water treatment and pharmaceutical (among others). The hydrocyclone can effectively separate particles larger than 10μm, but the efficiency is greatly reduced when the particle size is less than 10μm.
