The　batch　extractive　distillation　(BED)　process　has　the　advantages　of　both　batch　and　extractive　distillation.　It　is　one　of　the　most　promising　means　for　the　separation　of　azeotropic　and　close-boiling　point　systems.　However,　so　far　this　process　has　not　been　applied　in　industry　due　to　its　over-complexity.　A　new　shortcut　model　was　proposed　to　simulate　the　operation　of　the　batch　extractive　distillation　operations.　This　algorithm　is　based　on　the　assumption　that　the　batch　extractive　distillation　column　can　be　considered　as　a　continuous　extractive　distillation　column　with　changing　feed　at　any　time.　Namely,　the　whole　batch　process　is　simulated　as　a　succession　of　a　finite　number　of　steady　states　of　short　duration,　in　which　holdup　is　considered　as　constant　mole.　For　each　period　of　time　the　batch　extractive　distillation　process　is　solved　through　the　algorithm　for　continuous　extractive　distillation.　Finally,　the　practical　implementation　of　the　shortcut　model　is　discussed　and　data　from　the　laboratory　and　literature　are　presented.　It　is　found　that　this　model　has　better　adaptability,　more　satisfactory　accuracy　and　less　calculative　load　than　previous　rigorous　model.　Hence　the　algorithm　for　simulating　BED　is　verified.
