1.Application

Vehicle emissions of urea is a heavy duty diesel vehicles to achieve the four essential products. For urea is urea concentration was 32.5% and the solvent urea aqueous solution for ultrapure water, raw materials for urea crystal and ultrapure water. Heavy trucks, buses and other diesel vehicles to achieve the four emissions standards, be about to choose a suitable SCR on tail gas processing system, and the system must use urea solution to deal with nox in the exhaust gas. Therefore, automotive urea solution became heavy trucks and buses to reach the discharge standard of essential products.
