摘要
本文介绍了石油化工科学研究院研制成功的芳烃抽提模拟系统。它包括了对抽提塔、抽提蒸馏-汽提塔、闪蒸罐、油水分离、水洗和溶剂再生塔的计算,其中包含对具有23个化合物(20个烃、二甘醇、三甘醇和水)的非理想多元液-液和汽-液平衡的预测。该系统不但可用于模拟计算我国炼厂现存的四种不同流程的芳烃抽提装置,以改进和优化操作,也可用于对新装置的设计。从本文最后所列二个模拟计算实例看,其结果与工业操作数据具有良好的一致性。
A simulation system for aromatics extraction process has been developed bythe Research Institute of Petroleum Processing.It is capable of handling 23 com-ponents(20 hydrocarbons,diethylene glycol,triethylene glycol and wa(?)er)andpredicting nonideal multicomponent liquid-liquid and vapor-liquid phase equili-bria.lt includes modules for extraction towet,extractive distillation-strippingtower,flash drum,separator,water washer and solvent regenerator.The systemcan be used to sim(?)late the four different types of configuration in existingplants in Chinese refineries for operation improvement and modification and todesign new plants.Two examples are given for testing the simulation systemagainst actual plant data.
