摘要: Abstract A dividing-wall prefractionator configuration was investigated for a safe and economic retrofit of the conventional sequence using simple distillation columns. In proposed configuration, first column modified to dividing wall as supply prefractionated multi-feeds subsequent column. To investigate effectiveness nine near-ideal feed mixtures were considered analysis. The then compared with several other alternative configurations. efficiently generates multi-feed streams avoiding mismatch remixing effect low modification cost. Moreover, because allows flexible switching between operating mode, is also ensured by reducing operational risks. Several industrial cases studied validate configuration.
