Industrial Exhaust Gas Treatment

Industrial exhaust gas can contain various organic compounds, e. g. chemical by-products, solvents or odours. These volatile organic compounds (VOCs) or hydrocarbons (HC) are emitted during various industrial processes and need to be eliminated. Some applications also require a decomposition of nitrogen compounds such as NO_X, N₂O and NH₃.
The economic advantage of low operating costs and less stress on equipment materials of construction, compared to alternative technologies, makes catalytic technology the smart choice for many plants.
Our flexibility in manufacturing allows us to customise the catalyst according to the specific demands of various applications and equipment design.
Typical Application: Petrochemicals, Refineries, Fertilizers, Pharmaceuticals, Chemical Industries.

EnviCat® VOC

Many industrial processes emit volatile organic compounds (VOC) especially that involved in the use and manufacture of solvents, the production of specialty chemicals, and fertilizer manufacture.
Compared to alternative technologies catalytic oxidation technology offers the following advantages:

• Low temperature operation
• High Conversion Efficiency >99%
• Less severe Material Of Construction
• Lower Capital Cost
• Lower fuel consumption
• Lower Operating Cost
• Requires less space

We offer EnviCat® catalysts in various sizes and shapes:

• EnviCat® VOC for the catalytic oxidation of volatile organic compounds
• EnviCat® CO for the catalytic oxidation of carbon monoxide

Our speciality is the development of custom made catalysts according to individual requirements.
EnviCat® NO_X SERIES
Selective Catalytic Reduction (SCR) is a robust and cost effective technology for reduction of NOx from exhaust gases. The NOx reacts with NH3 and is reduced to nitrogen and water even in the presence of oxygen. SCR is widely accepted as the best available control technology.

Performance Benefits

• Well-proven catalytic technology for a highly effective removal of NOx exhausts
• Available as honeycombs or pellets
• Operation temperature range from 190° C up to 600° C
• Active for »Fast« and »Standard« SCR also in the presence of oxygen and humidity

The EnviCat® NOx series have been developed for plants operating between 1 to 10 bar and in a high oxygen environment.

N₂O Reduction:
N₂O has a life of 120 years and its global warming potential (GWP) is 280 times more than CO₂. EnviCat® N₂O catalysts are offered for reduction of N₂O in nitric acid plants

SELECTIVE CATALYTIC OXIDATION OF NH₃ (SCO) CATALYST:
SCO catalysts selectively oxidize Ammonia to Nitrogen with low NOx formation

Performance Benefits

• Significant advantage compared to noble metal catalysts where N₂O and NOx are the main products.
• Well-proven catalyst technology to achieve high levels of NH₃ conversion with only low formation of N₂O or NOx.
