Diesel Exhaust Gas Scrubber

Product Description

During diesel engine operation, number of harmful pollutants are produced in various quantities in the combustion chambers of diesel engines. Diesel engine exhaust contains harmful pollutants such as Hydrocarbons (HC) – (Aliphatic, Polyaromatic and Aldehyde) ,  Carbon Monoxide (CO) ,  Nitrogen Oxides (NOx) – (Nitric Oxide and Nitrogen Dioxide) ,  Sulfur Oxides (Sox),  Particulate Matter (PM) – (Carbon and Soluble Organic Fraction) .

APZEM uses catalytic technology to control the pollutants in exhaust emissions and it makes the air risk-free to breathe. This catalytic technology eliminates the harmful emissions by collecting diesel particles and burning off harmful pollutants.

The oxidation of harmful pollutants from Diesel engines

  • Carbon Monoxide : 2CO + O → 2CO2
  • Hydrocarbons         : HC + O2      →   H2O
  • Aldehydes               : HCHO + O2  →  CO2 + H2O
  • Particulate Matter: C (soot) + O → CO

For controlling NOX, selective catalytic reduction (SCR) technique is involved in emission reduction. In this technique, the exhaust emission is mixed with ammonia before passing through a layer of special catalyst at a temperature between 300 and 400°C, where by NOX is reduced to N2 and H2O. the reactions is as follows:

  • 4NO + 4NH3 + O2 → 4N2 + 6H2O
  • 6NO2 + 8NH3 → 7N2 + 12H2O
