METHOD OPTIMIZATION OF SEPARATE SECTIONS IN SUGAR PRODUCTION

method of thermoeconomic optimization separate section a typical sugar plant. was developed. Since the main part exergy losses is due to heat transfer at finite temperature difference, value drop in each s chosen as an independent variable with corresponding search for their minimum costs. The existence local fact that increasing increases amount energy costs (because increase) and decreases capital related surface sectione decreases), and, consequently, sum will have minimum. this unimodality cost function performed by Gauss-Seidel - sequentially comparing obtained step iteration previous ones if less, move on next iteration. If found becomes greater than step, which be optimal. Then total are calculated. As example application developed searching optimum optimums annual expenses first degree were found. exceeds existing evaporation system 2.6 maintaining such increased allows you reduce 3800 USD. It should noted values rigid link technological chain require mutual agreement, because flows coming from sections simultaneously included next, therefore level processes must change, thereby changing In addition, it taking change parameters within technology also cause leave system.
