Abstract

Citrus production is one of the main agro-industrial activities in Tucuman, Argentina, with a value in 2017 estimated at US$1,178 millions. Production of lemon juice concentrate requires the use of evaporation systems which are critical for the water and energy usage in all process industries. Precise knowledge of process variables is therefore extremely important for evaluation of the efficiency, economic parameters, etc. of the whole plant. In this work, data reconciliation and gross error detection were performed on data collected from the lemon juice concentration unit of an industrial plant located in Tucuman, Argentina. From reconciled data, the overall heat transfer coefficients of the four-effect evaporation line were calculated. In addition, a mathematical model was developed to predict the overall heat transfer coefficients. The parameters of the model were fitted to the experimental data and to the reconciled plant.
