AVOIDING THE HANG-UPS WITH UREA: Specialized coating allows Neptech's heated sampling lines and filter housings to avoid issues with urea corrosion, improving sampling accuracy in testing applications

摘要

There is no question that the application of selective catalytic reduction (SCR) systems using aqueous urea to reduce emissions from diesel engines has been one of the great success stories of the last 10 years. The technology has been adapted to diesels of nearly all sizes and has become the key NO_x reduction strategy for most mobile and stationary applications.
