How rigorously plant modeling can advance your urea business
ttempts making such urea models have been limited in scope and usage, due to the rapid rise in complexity, execution time, and difficulties encountered as model size increases to encompass sufficient fidelity and scope to address overall economic impact to the business. Urea plant models however can encapsulate a large amount of process knowledge and companies start realizing significant value from the use of these models in offline and online model based applications. Such applications include real-time optimization, model predictive control, data reconciliation, virtual sensors, process performance monitoring and total plant monitoring systems to name a few. This paper gives an overview on Stamicarbon’s capabilities and products related to urea plant modeling. These models are typically implemented in the ADVANCE and EVOLVE life-cycle of a urea plant. In 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.

How green is the Stamicarbon Urea process
an be solved in two different ways, either with an in–line and/or with an end-of-pipe solution. The combination of the equilibrium reaction and the presence of inerts make an in-line solution not feasible. Therefore end-of-pipe solutions to eliminate ammonia emissions in both urea melt and finishing plants are still needed to obtain a green and environmentally sustainable process. This paper covers the different available end-of-pipe solutions such as absorbers (including emergency absorber), acidic scrubbers and flares. These options have a wide range of operating windows for further optimization and achieving optimum environmental performance. Flaring reduces the ammonia emission by converting the ammonia into carbon dioxide and nitrogen oxides (NOx). Therefore, the environmental impact evaluation - after implementation of the new end-of-pipe solution - needs to be reviewed, especially when applying continuous emission flare because the environmental impact of these new type emissions are not more tolerable than ammonia emission. Stamicarbon believes that a green urea process combines optimum process conditions with a good choice of end-of-pipe solutions. The available alternatives for end-of-pipe solutions target an optimum “Triple P” balance, i.e. the balancing between financial-economical achievements (profit), environmental impact (planet) and public acceptance (people).
