Page 8 © Copyright Cal Gavin 5/ INHEAT Consortium Aim of the funded project bringing together existing knowledge of exchanger design, (component tubes, enhanced surfaces, fouling mitigation experience etc. extend current knowledge, where possible, to fill in the technology gaps facilitating a broad applicability of the resulting technology combinations. The results of the project will allow engineers to provide realistic upgrade capability with enhanced heat exchangers for existing process plants.
