Gas Cyclone and Hydrocyclone . There are two main designs of cyclone separator, these are the gas cyclone and hydrocyclone. Gas cyclones are used to remove entrained particles from a gas stream. Typical Gas Cyclone Installation. Hydrocyclones are used for separating fluids of different densities.
At low flow rates, the fluid spins at a lower velocity and the overall efficiency declines. At high flow rates, turbulence inside the hydrocyclone reduces efficiency. As a result, hydrocyclones work most efficiently at an intermediate flow rate, he said. Hydrocyclones can be installed downhole and have worked well in some reservoir performance ...
How does a hydrocyclone work? The hydrocyclone uses the pressure of the incoming fluid to generate a centrifugal force and flow pattern that can separate particles from a liquid medium. These particles must have a sufficiently different density to the liquid medium for separation to occur. The flow pattern in a hydrocyclone is cyclonic.

Generally, the most efficient …
The desalting process is similar to the dehydration stage in electrostatic coalescer. The difference is the injection of less saline diluent water and the use of a mixing valve for crude / diluent water contact. Desalting is a process whereby fresh water is mixed with the crude oil.
to optimise your process and plant. ... The result is that smaller diameter hydrocyclones can be used, or hydrocyclones can operate at lower pressures thereby saving on pumping energy. Slurry turbulence at the entry point into the cyclone is reduced as well as vortex finder wear, that can result in particle short-circuiting to the overflow ...
Hydrocyclones, otherwise referred to as cyclones, are mechanical separation devices that utilize centripetal or centrifugal forces within a vortex in order to sort particles present within a liquid suspension.

Looking into mineral process plant? Miner. Eng., 5 (1992), pp. 867-881.
The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation. ... A hydrocyclone can work upside ...
underflow. The result is a process with typically a 2-3 second retention time. This process provides a simple but effective separator with no moving parts. Because of the very high centrifugal forces inside the hydrocyclone separator vertical or horizontal installation orientation has no effect on separation performance. Solid-Liquid
Hydrocyclone separators are suited for small system applications, side-stream applications and individual equipment protection. They are used in the oil and gas, process, geothermal and mining industry. The hydrocyclone separator can also be used as pre-separator for flow streams that contains high levels of sand or other large organic debris.
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.
Cyclone separators or simply cyclones are separation devices (dry scrubbers) that use the principle of inertia to remove particulate matter from flue gases. Cyclone separators is one of many air pollution control devices known as precleaners since they generally remove larger pieces of particulate matter. This prevents finer filtration methods from having to deal with …

The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds of times greater …

Hydrocyclone separators are used worldwide in the mining and mineral processing industries for classification, de-sliming and de-watering applications. Their main purpose is to separate a stream of particles into different size fractions. However, they are also effective in applications where a fine slime fraction requires removal or where solids need to be dewatered as much as possible.
