Advanced Urea On-line Raman Analyzer (AURORA)

Advanced URea On-line Raman Analyzer (AURORA)

Urea plants have never been easy in the control and performance optimization. Large recycle streams and several constrains are hindering the process optimization job.
The performances of the urea synthesis strictly depends on thermodynamic equilibrium which is very sensitive to the operating conditions and especially depends on the compositions in the urea reactor and synthesis equipment.

In most of the plants there is the need of strictly monitoring the synthesis compositions, to utilize such information for understanding the process performances and correcting the process parameters.

AURORA is the new Casale on-line analyzer developed for the urea process control and optimization.
The new on-line analyzer is a “Real Time Performance Meter” which could be also used as smart sensor to enhance the performance of a Model Predictive Control.
