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.
Installation of a hydrodynamic separator along an Arizona highway. 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.
In this case the degasser may also act as a surge drum to ensure a steady flow of water to the treatment plant. Alternatively, it can be located downstream of produced water hydrocyclones. [4] In either case the degasser provides sufficient residence time to allow dissolved or entrained gases to be released from the produced water stream.
Produced water is a term used in the oil industry or geothermal industry to describe water that is produced as a byproduct during the extraction of oil and natural gas, [1] or used as a medium for heat extraction.
When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets of liquid from a gaseous stream.
When the water cut becomes high, or when a workover is considered, the economics will be evaluated [1] and may favor the installation of DOWS technology so that the waste water does not need to be treated at the surface. In those cases, the economics may favor injection of the produced water into a different permeable zone accessible to the ...
Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters. Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry .
Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment.
