Integrated Assessment in BIGCCS
I Systematic benchmarking of CO2 capture processes usingconsistent boundary conditions to
– Identify potential of capture processes– Provide directions for future research such as material development
I Muti-scale modeling of processes for integrated assessment

Single Stage Membrane
I Each membrane stage involves trade-off between product purityand capture rate.
– Played out as a trade-off between driving force (compression work)and membrane area.
I Significant work in literature on “sensitivity” analysis to designsingle stage systems.

Motivation
I Multi-stage systems required for post-combustion capture to95% product purity.
I For multi-stage process the design complexity increases further.I Identifying the “best” configuration for a given membrane is not
straight-forward.

Motivation for new approach
Would it be possible to develop a visual design methodology:I visually compare membranes?I indicates the potential of a membrane for different applications?I multiple stages can be designed using a single figure?I capture cost is incorporated to accurately reflect the area-energy
trade-off?

Summary
I A novel and elegant method for consistent design of membranesystems has been developed.
I The visual method allows for identifying the potential ofmembranes.
I A simple stage-wise method is used to design the process.I CO2 capture cost is incorporated in the design process.
