Integration of energy saving and emission reduction of an acetone-benzol dewaxing device
摘要
Abstract
Energy integration can not only improve energy efficiency, but also reduce water consumption and CO2 emissions. In this paper, the most practical process integration method - pinch technology-was used to optimize the existing heat exchanger network of an acetone-benzol dewaxing device. The unreasonable heat exchange and minimum utility consumption were identified. It was calculated that the energy-saving potential was about 4228.3 kW. The final retrofit scheme was based on the re-matching of several streams. The retrofit scheme for the heat exchanger network can save 1456.4 kW of heating utility and 524.2 kW of cold utility. The economic analysis of the optimized network showed that the energy cost can be reduced by 2.785 million RMB/yr, waste water productions can be reduced by 3000 tons/yr and the amount of CO2 emission can be reduced by 9078.2 tons/yr. According to the above analysis, optimizing the heat exchanger network can lead to remarkable water saving and CO2 emissions reduction. This study demonstrated that systematic analysis and optimization of an existing acetone-benzol dewaxing device could provide a practical way to improve energy utilization efficiency and reduce resource consumption.关键词
