1. Determinação experimental e modelagem de temperatura de ebulição e pH de sistemas binarios contendo compostos presentes em sucos de frutas / Experimental determination and modeling of boiling pont pH of binary systems containing fruit juice compunds
The vapor-liquid equilibrium of binary aqueous solutions of D-glucose and D-fructose, present in fruit juices, was evaluated by experimental boiling point measurements in a rotary evaporator with total reflux of the vapor phase from 20 kPa to atmospheric pressure (93.6 kPa) and concentration from 10 to 60 % by mass. The experimental data were correlated with

2. Avaliação experimental e modelagem da elevação do ponto de ebulição do leite adicionado de sacarose / Experimental evaluation and modeling of boiling point rise of milk added of sucrose
This work presents the experimental evaluation and the modeling of boiling point rise of milk added of sucrose. Samples of pasteurized milk with sucrose concentrations varying of (0 to 30) %, fat content varying in the range of (1.3 to 6.9) % and operational pressure varying among (50 to 750) mmHg were used. Dürhing and Antoine models were used for modeling

3. ELEVATION ON BOINLING POINT OF COFFE EXTRACT
The rise in boiling point of coffee extract was experimentally measured at soluble solids concentrations in the range of 9.2 to 52.4ºBrix and pressures between 5.8 × 10³ and 9.4 × 10(4) Pa (abs.). Different approaches to representing experimental data, including the Dühring's rule, the Antoine equation and empirical models proposed in the literature wer

4. Pinch analysis of evaporation systems
Evaporation systems are separation processes widely used in chemical industries. Some guidelines can be found in the literature for the process integration of multiple effect evaporators. In the published methodologies some aspects are neglected as boiling point rise, effect of pressure on latent heat of water, sensible heat of liquid streams, heat of mixing
