ＫｒｕｐｐＵｈｄｅ公司正在开发一种用于芳烃回收的萃取蒸馏改良工艺：ＳｕｐｅｒＭｏｒｐｈｙｌａｎｅ，目标是使能耗减少３０％，同时投资费用降低２０％。Ｍｏｒｐｈｙｌａｎｅ工艺是在１９６８年首次工业化的。该工艺采用Ｎ－甲酰吗啉为溶剂且采用双塔体系。第一个塔为萃
Krupp Uhde is developing an extractive distillation upgrading process for aromatics recovery: SuperMorphylane with the goal of reducing energy consumption by 30% while reducing capital costs by 20%. The Morphylane process was first industrialized in 1968. The process uses N-formyl morpholine as a solvent and adopts a two-column system. The first tower for extraction
