Manufactured by:Prantner GmbH Process Engineering based inReutlingen, GERMANY
The gas scrubbers are created as cross or countercurrent in horizontal or vertical design. In the packed columns, the exhaust air that needs to be purified is directed through the absorber in countercurrent to the washing medium. The mass exchange takes place in the packing materials zone. The packing materials are made of plastic or metal packages that have a large surface with low pressure ...

For the oxidation of air streams containing ammoniac from various processes, Prantner uses a catalytic unit that oxidises ammoniac in a gas-phase to environmentally neutral nitrogen. The amount of Nox produced is very low so that emission standards for nitrogen-oxides can be easily met. The combination of this selective catalyst with our existing recuperative or regenerative catalytic processes ...

Stripping is a physical process for the removal of undesired contaminants in water. Stripping out of the liquid phase works when the pollutant concentration in the gas phases is lower than the equilibrium concentration in the liquid phase system. The equilibrium is described using so-called Henry Constants. The Henry Constant is dependent on the pollutants in the system, the pressure and the ...

Prantner biological filters are used to treat waste gases with low concentrations of pollutants. For the efficient use of a biological filter, the following requirements must be met: The pollutant must be biologically degradable. Concentration of max. 0.5 g/m³. Adequate polarity of the substance (solubility). Easily adsorbed onto a filter ...

The contaminated air is passed over the fixed bed to adsorb the pollutants. The filters are standard equipped with sieve trays to hold the activated carbon. A broad range from small barrel filters to large 40” industry container filters is available. To change the loaded activated carbon, smaller filters are completely replaced. With larger container filters, the coal is renewed by means of ...

Automatic regenerating filters are used especially for concentrations of 0,5 - 20 g/Nm³ with highly chlorinated hydrocarbons such as perchlorethene. Steam regenerating filter units consist of fully automatic 2 or 3 bed activated carbon filters with an integrated control system. The filters are made from stainless steels or special materials such as PVDF or certain types of glass. Other ...

The Prantner solvent condensation allows highly contaminated exhaust air flows to be purified efficiently by cryocondensation. The solvents that are recuperated through the condensation process can often be led back into the production process directly. Thus, the efficiency of the proceeding is increased. The condensation proceeding is also combinable with a post-purification, e.g. with catalytic ...

The Prantner thermal oxidation system (TNV) offers you an extremely efficient air purification technology. Due to its robustness, this systems technology is optimal to be used even with compounds that are complex or afflicted with contaminated substances (e.g. silicon organic compounds). The capacity of the integrated heat exchanger system reduces the operating costs significantly. With regards ...

The contaminated exhaust air stream is passed through a process air fan to the adsorption rotor. In the adsorption sector of the rotor, the pollutants are adsorbed on an incombustible material and purified in compliance with the required threshold values for clean gas. In the desorption sector, the concentrated pollutants are again desorbed with hot gas and purified by means of the downstream ...
Manufactured by:Prantner GmbH Process Engineering based inReutlingen, GERMANY
In the first stage the bonded ammonium becomes free ammoniac under alkaline conditions and is transferred into the gas phase by being stripped with a Prantner packed column desorption unit. The free ammoniac is then treated in a catalytic air treatment system in the second stage.The ammoniac loaded air stream is sucked into the unit using a blower and is pre-heated to reaction temperature using ...

For catalytic deferrisation / demanganisation to a concentration of 8 mg / liter in water Prantner recommends the filter material pyrolusite. Pyrolusite acts as an insoluble catalyst and accelerates the reaction between dissolved oxygen and iron compounds. Pyrolusite acts as a catalyst between oxygen and soluble iron compounds and produces iron hydroxide which precipitates out and is easily ...

Prantner ion exchange systems were developed to remove a whole range of anions and cations from ...
Manufactured by:Prantner GmbH Process Engineering based inReutlingen, GERMANY
The process exhaust air is drawn in through a fan and preheated together with the purified air in a heat exchanger. The exhaust gas stream is brought to the necessary reaction temperature by an electric heater or a gas burner and then oxidized in the catalytic reactor to form carbon dioxide and water. The oxidation takes place in a specially-sized reactor. At higher pollutant concentrations (over ...
