求助!各位给翻译一下这两段话吧,谢谢了!看的头大了。 ...? Extractive distillation can be performed in continuous operating mode in a sequence of two extractive and regeneration columns or in a single-batch distillation column with at least three batch distillation steps. Differences exist between both operating modes as the batch mode offers more flexibility in terms of achievable product and larger operating parameter ranges.The parameter ranges can be assessed by analyzing liquid composition profiles in the column sections computed from an approximate model, before validation by simulation and experiments. Unusual extractive distillation processes exist: the process with ionic liquid entrainers [19] behaves like any heavy entrainer extractive distillation process. On the other hand, an extractive distillation process with a heterogeneous entrainer brings an additional flexibility both in continuous and in batch operation through reflux policies as in heteroazeotropic distillation [20e22]. 查看更多2个回答 . 4人已关注
