"Bottom-up for innovation."
Unit operation-based process design may not identify innovative equipment and energy system design. In this work, we depart from unit operation to phenomena building blocks. Combination of these building blocks generates equipment and process flowsheets.
Based on
the structured representation using
building blocks, and superstructure
optimization, we established
a unified framework for process
synthesis, integration, and
intensification and exploited the block structure to iteratively refine and discover novel designs. This also led to a computational
platform to automatically collects problem data, implements optimization, and
generates process configurations.

This is an ongoing project due to other research and funding priorities. Building block-based process synthesis and intensification involves isomorphic solutions. On top of developing symmetry-breaking constraints, we are working toward the elucidation on the symmetry structure's relationship between the expression graph of a symmetric optimization formulation and the expression graph of its relaxation. Based on this structure relationship, we intend to exploit the symmetry structure within
spatial branch-and-bound.
