芳烃抽提 也称芳烃萃取，用萃取剂从烃类混合物中分离芳烃的液液萃取过程。主要用于从催化重整和烃类裂解汽油中回收轻质芳烃(苯、甲苯、各种二甲苯)，有时也用于从催化裂化柴油回收萘，抽出芳烃以后的非芳烃剩余物称抽余油。轻质芳烃与相近碳原子数的非芳烃沸点相差很小（如苯80.1℃，环己烷80.74℃,2,2,3-三甲基丁烷80.88℃），有时还形成共沸物,因此实际上不能用精馏方法分离。利用芳烃在某些溶剂中溶解度比非芳烃大的特点，采用液液萃取方法可以回收纯度很高的芳烃。常用萃取剂有二乙二醇醚（二甘醇）、三乙二醇醚（三甘醇）、四乙二醇醚（四甘醇）、环丁砜等，也用二甲基亚砜、Ν－甲基吡咯烷酮、N-甲酰基吗啉等（见表）。1952年美国环球油品公司开发以二乙二醇醚为溶剂的尤狄克斯(Udex)法抽提芳烃，在休斯敦投产后，广为应用。 芳烃在重整汽油中含量高，不含烯烃、硫化物等杂质，处理较易。裂解汽油中含较多的二烯烃、烯烃、苯乙烯及少量的含硫、氮、氧的有机物，二烯烃很易聚合，硫化物很难从芳烃中除去。因此，从裂解汽油中抽提芳烃之前，必须进行二段加氢处理，以除去上述杂质。 工艺流程以二乙二醇醚处理催化重整汽油（见图）为例。原料在抽提塔中与溶剂逆流接触进行萃取，温度125～140℃，溶剂对原料比约15:1。抽提塔底物含溶解在溶剂中的芳烃，将后者送入汽提塔（见解吸）与溶剂分离，塔底的溶剂循环去抽提塔，塔顶产物送入芳烃水洗塔洗去残余溶剂后即为纯芳烃混合物。抽提塔顶的非芳烃，送水洗塔洗除残余溶剂。两个水洗塔底均为水与溶剂,去溶剂回收塔,蒸出水后，塔底溶剂去抽提塔循环使用。
