Hydro cyclone units are applied in order to separate coarse and fine solid particles from liquids . These type of separators are particularly capable of separating sand, starch, and other finely distributed materials. With hydro cyclones it is possible to separate fine particles online during the process. Hydro cyclone units are used to separate, classify, and to thicken suspensions. Also, these units are used to purify ores and minerals. Also, in fibre technique and paper industry they are applied in purification processes to separate dirt. Hydro cyclones are frequently run in parallel mode. The lay out and design of hydro cyclones are performed empirically similar to the duct cyclones. In the lower flow region of a hydro cyclone an air swirl forms during the separation process, which is not substantially influencing the cyclone flow. Because of the large dimension of the cyclone, wall friction has much more influence on the flow.

The gas cyclone belongs to the mostly applied technical separators, because it has applicationwise some fundamental advantages. One of them is certainly the fact that its construction does not show any movable components. For the large variety of different kinds of dispersed (particulate) phases (for example dust particles, metal chips, wooden waste, liquid droplets) and different gas conditions (pressure, temperature) the lay out and computation of a cyclone is still a complex task. Suvis has specialised in the development and lay out of cyclone separators and can offer professional solutions and consulting in the area of gas cyclones. Many years of experience gained through numerous cyclone development projects results in optimal solutions for our customers. A cyclone separator applies centrifugal forces and represents an effective apparatus for separating gas, liquid or solid particles from a continuous phase in chemical, process or environmental engineering.

The Suvis GmbH also deals with the application of modern numerical methods for the lay out and optimisation of various separator types like cyclones. A typical application of these computation methods is the computer aided investigation of particle separation from gases in cyclones. The prediction of the separation efficiency allows the reliable optimisation of conventional cyclones and the development of completely novel high efficiency cyclones. With that, very often expensive filter units, wet cleaner, or costly electro filters can be replaced or completed. When applying numerical methods (CFD simulations) to cyclones one encounters the problem of strong curvature of the stream lines because of the resulting strong swirl flow and the abrupt change of flow direction towards the outlet tube. This means that the assumption of isotropic turbulence is not useful anymore.

The jet - plus filter’s MEFM models are designed to purify air from dust. The dust is kept and air is discharged to the atmosphere through the outlet.It works in the pressurized (0.5 bar) and vacuum system

Our inline filter is intended for pipeline installation. It is small, compact and low cost. It is easy to replace under practical conditions and can be subsequently retrofitted with no problems. They are also suitable for a variety of applications in different sizes and materials.

Gas Filters WITT gas filters allow the reliable filtration of the finest dirt particles in gases. Depending on the respective version, the gas filters can filter out particles from 3 to 40 micron and extend the service life of downstream equipment. The WITT gas filters provide high flow rates and multiple connections. WITT gas filters can be used for many technical gases. The gas filters – with or without condensation outlet – are designed for installation in pipelines or at outlet points. Gas filters can be changed while installed.

There are various types of cylindrical and semicylindrical natural gas filters and they have various type of filters starting from filter paper to nonwoven synthetic media upon customer needs.

The air from the Granulators and the Coolers contains urea dust that is entrapped in Hamon’s scrubbers. In these industrially proven impact type scrubbers, efficiencies are very high and dust concentrations lower than 20 mg/Nm3 can be achieved at the stack outlet. The total amount of urea collected by these scrubbers is recycled, for reconcentration, to the process.The same process is used to capture NH3 from the gases at the outlet of the Fertilizer Industry.

ReACT™ (Regenerative Activated Coke Technology) is an advanced multipollutant technology that achieves simultaneous capture of SOx, NOx and mercury in one vessel.The process was first developed in the 1970s in Germany, was subsequently advanced and commercialized in Japan where ReACT™ has been implemented at three large scale coal-fired power plants and at several steel mill and refinery applications:The 321-MW Wisconsin Public Service Weston Power Plant, Unit 3 is equipped with a ReACT™ system engineered and supplied by Hamon Research-Cottrell.Hamon Research Cottrell offers ReACT™ under a license agreement from J-Power Entech.

Besides primary measures, Selective Catalytic Reduction (SCR) is the most effective method for controlling nitrogen oxide emissions (NOx) from combustion sources. It is a commercially proven flue gas treatment technology that has been demonstrated to remove over 98 percent of the NOx contained in combustion system exhaust gas. The catalyst is at the heart of the SCR process. It creates a surface for reacting the NOx and ammonia, and allows for the reaction to occur within typical flue gas temperature ranges.Hamon uses a similar technology to reduce also VOC or CO content.Thorough knowledge in the design of all types of heat recovery systems including heat exchangers made of glass or fluoroplastic tubes to de-saturate the flue gas downstream a wet scrubbing system allows for minimum energy consumption when the flue gas needs to be heated.

Hamon Research-Cottrell provides process and equipment expertise, drawn from more than fifteen years of experience with the patented Urea to Ammonia U2A® technology, starting from bench and pilot scale, through systems for small gas turbine SCR and the largest utility scale SCR systems for coal and gas fired boilers.Hamon Research-Cottrell’s U2A® system provides several benefits:Urea as feedstock eliminates the hazards associated with the transport, transfer and storage of toxic anhydrous or aqueous ammonia.Compared with using 19% aqueous ammonia, energy use is reduced.Process control response provides ammonia on demand, easily following load conditions.Hamon Research-Cottrell offers U2A® on a worldwide basis and has installations in Europe and the Middle East in addition to a large installed base in the United States.

Selective Non-Catalytic Reduction is a post-combustion technology that is designed to control nitrogen oxides (NOx) emissions from boilers by the injection of ammonia or urea reagents into the flue gas.Hamon Research-Cottrell is licensed by Exxon Mobil for the application of ammonia based Thermal DeNox™ (TDN).

Gas Detection Systems use Interference Bandpass Filters to identify the emission of a type of gas. Different gases emit at a specific wavelength which makes it identifiable when using a relevant Interference Bandpass Filter. These wavelengths are: Carbon Monoxide (CO) @ 4.73μm Nitric Oxide (NO) @ 5.24μm Nitrogen Dioxide (NO₂) @ 6.17μm Sulphur Dioxide (SO₂) @ 7.42μm Hydrogen Chloride (HCl) @ 3.55μm Carbon Dioxide (CO₂) @ 10.7μm Knight Optical provide a wide range of interference bandpass filters that can be used with gas detection. The Interference Bandpass Filters would be need to transmit in the infrared region. These would be a customised item, which we are very experienced in. We provide narrow, standard, broadband and extra broadband filters with a high optical density of 4 as standard, however this can be customised for you. For more information read PDF
