Pinch Analysis for Energy Optimization in Chahar Mahal Sugar Factory

Pinch technology used as a tool for energy calculation and target design in context of energy optimization. In 2004، After enthalpy-exergy analysis for Chahar mahal beet sugar factory and applying some changes in heat transfer system، the steam consumption per beet decreased by 34% compared previous year. To enhance the efficiency of energy utilization، pinch analysis was employed to get a better insight into the energy situation in 2004. Based on the results obtained، three tubular heat exchangers were added to the heat exchanging system at a position which by exergy analysis was founded tobe the best، The results showed that the steam consumption per unit weight of beet sugar decreased from 54% in 2004 to 46% in 2005.
