A partially demolished factory with dominating cyclonic separators. Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used.
Hydrocyclones are a type of cyclonic separators that separate product phases mainly on basis of differences in gravity with aqueous solutions as the primary feed fluid. As opposed to dry or dust cyclones, which separate solids from gasses, hydrocyclones separate solids or different phase fluids from the bulk fluid.
In civil engineering (specifically hydraulic engineering), a hydrodynamic separator (HDS), also called a swirl separator, is a stormwater management device that uses cyclonic separation to control water pollution. They are designed as flow-through structures with a settling or separation unit to remove sediment and other pollutants.
Cyclone separators are found in all types of power and industrial applications, including pulp and paper plants, cement plants, steel mills, petroleum coke plants, metallurgical plants, saw mills and other kinds of facilities that process dust. [citation needed] Single-cyclone separators create a dual vortex to separate coarse from fine dust.
All venturi scrubbers require an entrainment separator because the high velocity of gas through the scrubber will have a tendency to entrain the droplets with the outlet clean gas stream. Cyclonic, mesh-pad, and blade separators are all used to remove liquid droplets from the flue gas and return the liquid to the scrubber water.
Bomb cyclones form when the conditions at the surface and at the jet stream level are ideal for the storm to intensify. The jet stream is a narrow band of strong winds in the upper atmosphere.
For example, if the fluid being put through the lamella clarifier comes from a heavy industrial plant it may require post-treatment to remove oil and grease especially if the effluent is going to be discharged to the environment. A separation process unit such as a coalescer is often used to physically trigger a separation of the water and the ...
