A new integrated approach for synthesis, design and operation of separation
schemes is presented. This integrated approach is based on driving forces
that promote the desired separation for different separation techniques. A
set of algorithms needed by the integrated approach for sequencing and desi
gn of distillation columns and for generating hybrid separation schemes are
presented. The main feature of these algorithms is that they provide a 'vi
sual' solution that also appears to be near optimal in terms of energy cons
umption. Several illustrative examples highlighting the application of the
integrated approach are also presented. (C) 2000 Elsevier Science Ltd. All
