芳烃抽提装置节能优化及效果

Energy-saving Optimization and Effect of Aromatic Hydrocarbon Extraction Unit

通过对芳烃抽提装置的能耗分析,找出影响能耗的主要因素,通过降低再沸器的蒸汽品位、换热网络的进一步优化和后路流程优化等措施,降低蒸汽消耗。优化措施实施后,节能效果良好,对降低装置燃动成本具有重要意义。

By analyzing the energy consumption of aromatics extraction unit,the main factors affecting energy consumption were found out,and the steam consumption was reduced by reducing the steam taste of reboiler,further optimizing the heat exchange network and optimizing the back-end process.After the implementation of the optimization measures,the energy saving effect was good,being of great significance to reduce the burning cost of the device.
