Industrial processes requires the evaluation and the monitoring of some water properties like Electrical Conductivity (EC) and Langelier Saturation Index LSI), which are of interest for the estimation of water quality. Analytical representation of water properties can be useful in Process Modelling and Simulation of industrial systems. The use of common simulation softwares allows to test industrial processes under conditions that cannot be easily or safely tested; nevertheless estimation of Electrical conductivity and Langelier Saturation Index is usually not possible or requires particular software licenses. Application of unconventional techniques can fix the problem. In particular for Aspen Plus commercial software the availability of customizable calculator blocks allows the user to represent specific features. The paper presents the unconventional method developed to calculate EC and LSI values in Aspen Plus modelling FORTRAN based calculator blocks starting from literature information.
