Catalysis provides clean, dry air
A
Beko Technologies product story

Oct 4, 2007
The Bekokat operates independently of the ambient conditions, oil inlet concentration and relative humidity of the compressed air.
Beko Technologies has developed the Bekokat catalysis method for compressed air processing.
It offers oil-free, dry air produced in a single process step after compression.
The system offers the total oxidation of hydrocarbons in compressed air.
In the automotive industry, catalytic convertors are used for petrol and diesel engines.
Contaminants in the waste gas, in particular hydrocarbons, are combusted to carbon dioxide and water vapour.
Bekokat technology makes use of this principle for compressed air.
In the compressed air of oil-lubricated compressors, hydrocarbons are present in the form of lubricants and oils, and further air components in the form of gas, vapour and aerosols.
The Bekokat systems convert these substances into carbon dioxide and water.
A pressure vessel is filled with a granular material.
The entire vessel is heated up to an operating temperature of 150C.
The oil components of the compressed air streaming through the heated vessel are then fully converted into water and carbon dioxide at the surface, in the pores of the granular material of the catalytic convertor.
Subsequently, the purified compressed air is cooled down in a heat exchanger to a temperature of 10 to 15C higher than at the inlet and is available for the application.
The Bekokat operates independently of the ambient conditions, oil inlet concentration and relative humidity of the compressed air.
Fully de-oiled compressed air leaves the vessel.
The air is so clean that it may be used as breathable air.
The condensate accumulated during the cooling down of the compressed air is also absolutely oil-free and can be discharged into the sewage system without processing.
The Bekokat granular material requires replacement only after 20000 hours.
Melanie Muller-Preuss, Bekokat Product Manager said "With Bekokat, we produce oil-free compressed air from oil vapours and aerosols".
"With this, we outperform even the severe requirements on compressed air in accordance with DIN EN8573-1/ISO 8573-1, class 1oil content".
"This also applies to higher inlet temperatures up to 100C and to partial load operation".
"Even the best commercially available filters reach their limits in this case".
"With Bekokat, we open up new markets, for example with regard to compressed air solutions for clean and ultraclean rooms".
