摘要
简介了国内外芳烃分离溶剂抽提的5种方法:Udex法、环丁砜(Sulfolane)法、N-甲基吡咯烷酮(Arosolvan)法、二甲基亚砜(DMSO)IFP法及N-甲酰基吗啉(Formex)法。比较了抽提蒸馏(ED)、重整汽油抽提蒸馏脱苯工艺(SED)和环丁砜工艺技术经济指标。
Five methods in solvent extraction for separating aromatics in China and abroad were introduced, including Udex, Sulfolane, Arosolvan, DMSO and Formex processes. A simply economic analysis in extractive distillation, sulfolane and Co - solvent extractive distillation, and solfolane Crafts was given.
