DEF/NOx reduction
Stamicarbon offers technology concepts to produce 32.5% urea-in-solution - often known as AUS32 or Diesel Exhaust Fluid (DEF) - for NOx reduction in diesel engines. As a licensor of urea technology, Stamicarbon is in an ideal position to develop a state-of-the-art solution not only taking into account the current regulations but also anticipating future developments and requirements.

UAN Design
Stamicarbon’s integrated urea-ammonium nitrate (UAN) Design process allows for a simple design and low investment and operating costs. In an integrated plant, the end product remains in liquid form and can be easily transported and stored in tanks, allowing for the abolishment of expensive prilling or granulation equipment. The design also enables the production of DEF (Diesel Exhaust Fluid)/AdBlue®.

UAS Design
In order to meet the increasing demand for sulfur-based fertilizers, Stamicarbon has developed a flexible modular process for the production of urea ammonium sulfate (UAS). The addition of ammonium sulfate to urea also reduces nutrient loss due to ammonia volatilization. The UAS granulation process includes four main modules: suspension, granulation, evaporation and scrubbing module.
