As the world's leading UREA authority we are committed to the long-term success of this industry - and that means sharing our insight and knowledge.
s that are out of specification, intermediates and by-products, all of which normally end up as waste. These waste streams are either dumped in landfills, incinerated, or otherwise wasted, putting a burden on the environment and resulting in a negative economic impact for fertilizer producers.
the LAUNCH phase, grass root plants can apply the models to optimize consumption and emission figures. It allows urea producers to stay competitive with production improvements, monitoring and detection, staff training and full lifecycle support. Further, feedback will be given on the EVOLVE OPTIMIZER™ project at OCI in the Netherlands. This has been in operation since 2012.
who have a thorough knowledge of the dynamic behavior of the process and the spectrum of algorithms which can be implemented in the process control system. The optimization process itself consists of several steps, like setting up a controller performance monitoring system, determining the root cause of poorly performing control loops, fixing potential hardware problems, and tuning the controllers with the proper algorithm and parameters. These well-tuned basic control loops can also act as a solid backbone for model-based advanced process control software like the Stamicarbon EVOLVE OPTIMIZER™, which offers extensive possibilities for stable plant operation and further enhanced economic benefits.
