All of them follow the established pattern of Pinch Analysis of setting targets prior to design. The eight developments are: pressure drop optimization; batch process integration; multiple base case design; water and waste water minimization; distillation column profiles; total site integration; low temperature process design; and emissions targeting. The paper concentrates on the essence not the detail. Case studies are described and scope and impact of practical applications are assessed. For details of methodology, the reader is referred to the relevant references. To complete the overview, the paper provides a comprehensive summary of previous literature. (author)
