When using measured values in a process model, you have to be aware that the measured values are never consistent. Since measurements are always subject to errors, the values will not always satisfy the model equations. Basic principles, like conservation of mass and energy, will not always be satisfied.
Process engineers often attempt to solve those kinds of problems by identifying “reliable” values and disregarding others. However, this approach is not satisfying since it is time consuming and not repeatable.
Using IPSEpro-PSValidate you can use well-defined, standard numerical methods that enable you to use all of the measured data values available and exploit redundancies in that data you to improve your results.
The PSValidate data validation software uses statistical methods to eliminate redundancies and to obtain more accurate data. It enables you to:
