摘要:

基于Aspen Plus软件的UNIFAC模型,筛选了4种离子液体;在无限稀释状态下,通过评估4种离子液体对芳烃与非芳烃混合体系的选择性,确定了1⁃乙基⁃3⁃甲基咪唑甲磺酸盐([EMIM][MESO3])离子液体适合作为萃取剂;分别建立环丁砜⁃芳烃抽提模型和[EMIM][MESO3]⁃芳烃抽提模型,采用灵敏度分析和正交实验对两种模型工艺参数进行优化,确定了最佳的工艺参数。结果表明,在分离效果上,[EMIM][MESO3]⁃芳烃抽提工艺优于环丁砜⁃芳烃抽提工艺;在能耗和经济性分析方面,与环丁砜⁃芳烃抽提工艺相比,[EMIM][MESO3]⁃芳烃抽提工艺中冷却器和加热器的能耗分别降低69.58%和46.38%,年度总投资(ΔTIC)、年度运行成本(TOC)和年度总成本(ΔTAC)分别降低30.15%、30.08%和30.13%。

Abstract:

Four ionic liquids were screened using the UNIFAC model in Aspen Plus. At infinite dilution, their selectivities for aromatic/non⁃aromatic mixtures were evaluated, and 1⁃ethyl⁃3⁃methylimidazolium methanesulfonate ([EMIM][MESO3]) was selected as the extractant. A sulfolane⁃based aromatic extraction model and an [EMIM][MESO3]⁃based aromatic extraction model were then established. Sensitivity analysis and orthogonal experiment were used to optimize the process parameters of the two models and determine the optimal operating conditions. The results show that the [EMIM][MESO3]⁃based extraction process provides better separation performance than the sulfolane⁃based process. In terms of energy consumption and economics, compared with the sulfolane⁃based process, the [EMIM][MESO₃]⁃based process reduces cooler and heater energy consumption by 69.58% and 46.38%, respectively. The annual total investment (ΔTIC), annual operating cost (TOC), and annual total cost (ΔTAC) are reduced by 30.15%, 30.08%, and 30.13%, respectively.
