Developments And Challenges In Urea-Scr Aftertreatment System: Review

Abstract

Due to their efficiency and reliability, diesel engines are regarded as the most effective power generators in the manufacturing and haulage industries. However, they are plagued by the negative effects of exhaust emissions, particularly oxides of nitrogen (NOx), which are subject to increasingly strict emission rules, prompting the search for alternative technologies. Urea-SCR is a sophisticated energetic emissions reduction technique that uses a catalyst and urea-water solution (UWS) to convert nitrogen oxides (NOx) into harmless byproducts. Current study deals with the various factors effecting Urea-SCR system implementations, along with advantages, and future challenges.
