Exhaust gas cleaning
Harmful components in exhaust gasses like nitrogen oxides(NOx), carbon monoxide(CO) and incompletely burned hydrocarbons(mainly ethylene, C2H4) are converted in two steps(SCR and OXI) into harmless components like Nitrogen(N2), carbon dioxide (CO2) and water (H2O).
If besides heat and electrical power CO2 can be used as well, the production can be increased up to 20-30%.
