Rethinking ethanol separation in continuous spirit production from a process intensification perspective

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Continuous neutral‐alcohol and food‐grade ethanol production is an energy‐intensive process in which distillation and rectification alone account for 50–85% of total plant energy use. While significant advances in separation technology have emerged over the past two decades, the spirits industry continues to rely predominantly on multi‐effect ...
