SUMMARY
The discussion clarifies that Adblue, a solution containing 33% Urea, is utilized in Selective Catalytic Reduction (SCR) systems because ammonia is the required reactant for effective operation. Using 100% Urea is impractical due to its solid state and limited solubility in water, which would hinder the necessary chemical reactions. The solubility of Urea at 20 °C is 107.9 g/100 ml, indicating that a diluted solution is essential for optimal performance in SCR applications.
