Abstract:

The rising cost of energy and environmental concerns has led the Sugar industry to search for reducing energy consumption in operations. In this paper, pinch analysis was applied to a typical Sugar Industry process to target its energy requirements. Hint software was used for the analysis. At the chosen ΔTmin of 10˚C, the industry's minimum cooling and heating utility requirements were studied and determined 46594 kW and 3258 kW, respectively, with a pinch temperature at 113˚C. The company's hot utility requirements before (traditional) and after pinch analysis approach were found to be 45574 KW and 3258 kW, respectively, while the cold utility requirements were 102393 kW and 46594 kW, respectively, which presented an energy-saving potential of 62.9 %.
