摘要

针对原料油中饱和分与芳香分分离精度低导致糠醛精制工艺抽余油收率低、抽出油质量差的问题，提出基于热力学相图分析的糠醛精制工艺的改进策略。基于虚拟组分法简化润滑油组分为饱和分、芳香分和极性分，采用NRTL模型预测不同温度下的相平衡数据，分析抽提过程液液相平衡关系及操作条件对萃取过程的影响规律，发现温度是影响平衡组成和传质效率的关键因素。基于相图对萃取过程的分析，通过设计多级抽出液回收系统，多温度梯级分离抽出液，解决抽提塔在较低温度下难以操作的问题。结合实际糠醛精制装置进行模拟计算，结果表明设置多级抽出液回收系统，抽提过程溶剂比及冷热公用工程量适当增加，抽余油收率较原工艺提高10%以上，抽出油质量极大改善，显著提升糠醛精制工艺的分离效率。

Abstract

This paper is focused on improving the quality of the extracted oil and the yield of raffinate oil in the furfural process. Retrofit scheme for furfural refining process is proposed

figuring out the low separation efficiency of saturated and aromatic components. Adopting the virtual component method

the lubricating oil components are simplified into saturated

aromatic and polar component. The NRTL model is employed to predict the liquid phase equilibrium data at various temperature. With the analysis of temperature and solvent

the phase equilibrium temperature is the key point to affect the composition of liquid-liquid equilibrium and mass transfer efficiency. Based on the analysis of extraction process by phase diagram

a multi-stage extraction liquid recovery system for separating the extracted oil by temperature reduction step was proposed

resolving the difficulty of operating at lower temperatures. The simulation calculation was carried out in combination with the practical furfural refining unit. The results showed that designing a multi-stage extraction liquid recovery system，the solvent ratio

the heat and cold utility in the extraction process increased slightly. However

the yield of the raffinate oil is increased by more than 10%

and the quality of extracted oil is significantly improved. The separation efficiency in lubricating furfural refining is greatly improved.
