This project demonstrated this technique’s potential (NMR) in the correlation and estimation of properties, for the purposes of procedural control. Using this technique, besides increasing the speed at which analytical results are obtained, has been fundamental in determining product properties. That was the case of the identification and characterisation of contaminants, as well as in developing applications for predicting characteristics of gasoline and fuel oil, for the purpose of product validation and procedural control.
Based on the use of this technique, a mathematical model of fuel oil viscosity prediction, already implemented in the fuel oil production control system, was developed at the fuel factory of the Matosinhos refinery.
Another important result of this work consisted in an economic assessment of an investment in an online monitoring equipment of the characteristics of fuel oil, based on this technology. According to the analysis carried out, this monitoring should contribute to the optimisation of the use of fluxes in fuel oil production, with considerable economic savings.
