Finding cost effective retrofits for heat exchanger networks remains a challenge. Whilst it is often straightforward to find retrofit changes to an existing network that can improve energy performance, in practice such changes are most often uneconomic. This paper will present an approach to...

Improving energy recovery with retrofitting heat exchanger network has been widely studied in academic and industrial communities. Distinct from most of existing works on HEN retrofit neglecting exchanger geometry, this paper presents a novel optimization method for dealing with the main...

The importance of exploiting degrees of freedom within a crude oil distillation process for improving energy performance has been a feature of process integration from the earliest days. Combining process changes with changes to the heat recovery system leads to far better results, compared with...
