TTPL offers customized systems optimized to suit the requirement and application based on the parameters of exhaust gases, emission requirements, site conditions availability and cost of input materials etc. TTPL offers DeNOx / NOx Reduction Systems with following processes

1. Selective Catalytic Reduction Process (SCR)

Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, (also referred to as NOx) with the aid of a catalyst into diatomic nitrogen and water. A gaseous reducing agent, typically anhydrous ammonia, aqueous ammonia or urea, is added into a stream of flue or exhaust gas and is adsorbed onto a catalyst. Carbon dioxide is a reaction product when urea is used as the reducing agent. The Overall SCR DeNOx plant has two major components: Urea Preparation System and SCR DeNOx / NOx Reduction System. Urea solution is prepared in Urea System. The flue gas is treated using the urea as solution in SCR DeNOx / NOx Reduction Systems.

2. Selective Non-catalytic Reduction Process (SNCR)

Selective Non-catalytic reduction process is a post-combustion NOx control method that reduces NOx via injection of ammonia or urea based reagent into the furnace. As SNCR requires an elevated temperature, it is sometimes referred to as thermal reduction. The resulting product of the chemical reaction is nitrogen, carbon dioxide, and water.
