Diesel Engine Emission Control

Commercial vehicles, heavy-duty trucks, logistics fleets, city buses and coaches are the core AdBlue/DEF applications. SCR systems inject urea solution to reduce NOx to nitrogen and water, meeting China IV–VI and Euro IV–VI standards.

LV BAI JIA DEF supports the full range of SCR-equipped diesel vehicles for compliant fleet operation.

Agricultural and Off-Road Machinery

Tractors, combine harvesters and other agricultural equipment, alongside excavators, bulldozers and mining trucks, all rely on urea solution for NOx control to meet emission standards.

Lvyan Chemical products cover off-road mobile machinery urea needs.

Industrial Boilers and Power Plants

Coal, oil and gas power plants and industrial boilers produce large amounts of NOx during combustion. Injecting urea solution into the SCR system effectively cuts NOx emissions and meets increasingly strict environmental regulations.

Industrial denitrification urea products are widely used by power utilities and industrial boiler customers.

Comparison

Why urea beats aqueous ammonia

Production & Use
UreaSolid granules or solution — easy metering, no high-pressure ammonia system
AmmoniaRequires dedicated synthesis, storage and injection equipment
Storage & Transport
UreaAmbient storage, safe transport, no toxic leak risk
AmmoniaLiquid ammonia is hazardous — requires pressurized tanks and special carriers
Sales Price
UreaLower total cost of use with less maintenance
AmmoniaHigh equipment investment and safety/operation costs
Technical Difficulty
UreaMature process, minimal retrofit, easy to deploy
AmmoniaComplex system design, strict operator qualification required
Product Stability
UreaStable properties, low volatility, consistent batches
AmmoniaProne to volatilization and leakage, demanding storage conditions
