CO2 removal from flue gas emitted by coal fired power plants is an important objective for process sustainability. However, solvent regeneration in state-of-the-art absorption processes results in power plant efficiency losses of 7 to 15 % (Neveux et al., 2013). Process intensification, combining different and innovative technologies for gas separation, can result in highly efficient processes capable of reducing the energy penalty caused by CO2 capture. Current approaches for conceptual process design (CPD) however rarely consider emerging technologies like membrane contactors or hybrid process configurations. We present a multi-stage approach to overcome this drawback, which bases on process decomposition in different levels, combined with an efficient screening of promising materials and process design variants by means of shortcut methods. The approach follows the idea of an iterative refinement, in which the modeling accuracy increases while the number of process variants decreases.
