Phenomena Based Methodology for Process Synthesis Incorporating Process Intensification

Process intensification (PI) has the potential to improve existing as well as conceptual processes, in order to achieve a more sustainable production. PI can be achieved at different levels, that is the unit operations, functional, and/or phenomena level. The highest impact is expected by looking at processes at the lowest level of aggregation which is the phenomena level.

In this paper, a phenomena based synthesis/design methodology incorporating process intensification is presented. Using this methodology, a systematic identification of necessary and desirable (integrated) phenomena as well as generation and screening of phenomena based flowsheet options are presented using a decomposition based solution approach.

The developed methodology as well as necessary tools and supporting methods are highlighted through a case study involving the production of isopropyl acetate.
