ERC Emise Redukce Concepty s.r.o.

We have become one of the leading companies in the denitrification field of combustion plants (improved combustion processes with lower emissions) in Czech and Slovak Republic market.

Our company has a wide range of technologies and know-how for comprehensive solution to greening (especially the reduction of nitrogen oxides – NOx in the flue gas) and economization of the combustion plants.

Slide 1

SNCR

Selective non-catalytic reduction

Ammonia (urea or ammonia water) reacts with the harmful nitrogen monoxide (NO) and nitrogen dioxide (NO₂) from the flue gas into harmless nitrogen (N₂) and water.

The reaction temperature is 880 to 10800 °C (max. range 850 - 1100 °C).

Slide 2

SCR

Selective catalytic reduction

Ammonia reacts with the harmful nitrogen monoxide (NO) and nitrogen dioxide (NO₂) from the flue gas into harmless nitrogen (N₂) and water.

The reaction temperature is 200 to 450 °C.

Slide 3

ERC - plus

Selective catalytic + non-catalytic reduction

This variant of DeNO_X technology combines advantages of both (SNCR and SCR) basic DeNO_X technologies.

The ERC - plus process is applied
if strict requirements are made on the secondary ammonia emissions (NH₃ slip) and if NO_X reduction rates are required which cannot be achieved by the pure SNCR process.

More information

We offer two basic option for emission reducing:

• Primary measures – adjustment of the fuel a combustion plant before its combustion
  ⇒ ERC – process additives (additives)- we produce special additives for liquid and solid fuels, which are intended for:

• • improve combustion
  • reducing SO₃, corrosion, deposits on heat transfer surfaces
  • NO_X reduction

• Secondary measures – reducing the concentration of pollutants in the environment, generated during the combustion process
  ⇒ ERC – denitrification system (DeNO_X) – We design and produce products for flue gas denitrification using following methods:
  • SNCR
  • SCR
  • combination of these methods (SNCR-SCR).
