Abstract

The aim of this paper was evaluation the exergetic performance of quintuple effect evaporators units in raw sugar production processes. The energy analysis in the raw sugar production process has been using basic thermodynamic principles to evaluate the performance of the quintuple effect evaporator. However, the energy principle is not enough to find out resource utilization. This study showed the exergy and advance thermodynamics analysis to evaluate quintuple effect evaporator performance for use in the improvement of the energy efficiency of system. The research was on actual processing conditions. The raw sugar production process was evaluated using key indicators to measure the effectiveness, exergy losses, exergetic efficiency of each evaporator and overall effects. The results from analysis by exergy showed that the highest exergy loss was at the first evaporator with 23,100.04 kW, 49 % of exergy input. Whereas the third evaporator had the highest exergetic efficiency with 92.40 %. Furthermore, there is moderate exergy loss at the fourth evaporator. Other effects of exergy destruction of the quintuple effect evaporator were identified. The analysis results can be used for improving energy saving, design, equipment operation and overall sugarcane production process.
