抽提能耗流程优化研究

Study on process optimization of extraction energy consumption

通过对芳烃抽提装置工艺进行优化改造,将液-液抽提改造为抽提蒸馏,减少了蒸汽用量,提高了整体经济效益。

By optimizing the process of aromatics extraction unit,liquid extraction was transformed into extraction distillation,which reduced the amount of steam and improved the overall economic benefit.
