EWK Environmental Engineering has been manufacturing systems for the purification of air and waste gases for years.The SCR (selective catalytic reduction) methods successfullyused for the reduction of pollutants in Process exhaust air Combustion gases The burning of biological fuels, (wood, straw, biogas etc.) as well as fossil fuels (heating oil, natural gas, heavy oil, coal) and industrial waste (solvent, sewage sludge, explosive, refuse and industrial residue etc.) generates large amounts of the following substances even in the most advanced furnaces: Nitric oxide NOx Carbon monoxide CO Hydrocarbons CmHn Dioxin / Furan PCDD / PCDF With the SCR catalyser technology these air pollutants can be precipitated to a large degree and converted to N2, CO2, H2O. Modular construction The EWK reactors consist of modules set in stainless steel casings with insulation. This permits an individual assembly depending upon the kind of pollutant and pollutant concentration. Individual adaption to local requirements. Compact and economical construction.SCR catalyzer technology is characterized by: simple operation low maintenance effort long lifetime high operating safety low operating costs easy upgrading of existing systemsAdvantages of the SCR-technology with the reaction medium urea Urea is non-toxic, transportation and storage hold no risks NOx conversion rates of over 98% are possible no or negligible reaction by-products low ammonia slip
Fabric filters are an alternative to dry type electrostatic precipitators and are suitable primarily for dry dust. Adressing individual operating conditions:
Although scrubbers are among the simplest dust arrester, they can be used in a multitude of applications. They do not only serve as dust removers, but are also used ...
The use of techniques, which separate the emissions absorbed by the liquid is necessary for wet waste and process gas purification systems.
Whether pre-purification, ...
Dry type electrostatic precipitators today are considered the most economical system for solving dust collecting problems, as any dry dust generated can be disposed ...
By integrating water/water or water/air heat-exchangers into the absorbent cycle of the scrubber it is possible to transfer large amounts of usable heat energy from ...
