The framework provides a simple and intuitive understanding of why different types of divided wall columns save energy when they are compared with corresponding conventional distillation sequences. Furthermore, analytical expressions are derived to quantify the potential energy saving of divided wall columns based on remixing. The method is illustrated with some real mixture examples often seen in the literature. ? 2010 American Chemical Society.[SDGs]SDG7Analytical expressions; Distillation sequences; Intuitive understanding; Save energy; Distillation; Energy conservation; Potential energy; Distillation columnsjournal article10.1021/ie901907e2-s2.0-79952803159https://www.scopus.com/inward/record.uri?eid=2-s2.0-79952803159&doi=10.1021%2fie901907e&partnerID=40&md5=dcfdce14e686e7f4fae0189ddf1cf29d
