The paper explores the dangers for careful process design using new materials and processes that may arise because of the state of understanding of the properties of those materials. Evolution of the sciences of molecular modelling and of thermophysical property theory is explored and it is clear that both have a considerable amount to contribute to careful process design in the future. However, it is equally argued that the evolution of the experimental database upon which th e design of conventional processes has been based may not be evolving in such a favourable direction. By means of examples it is shown that what was the basis for the past success of thermophysical property provision, is being undermined by modern scientific behaviour and that there is ample evidence that when new materials are encountered the system that has been in place to validate data is simply lacking its full force.The consequences of this lack of rigour in property provision for the databases on novel, perhaps especially biological processes, needs careful consideration. |
