Gas system cascade analysis framework for optimal design of biogas system

The main objective of this research is to develop a new framework called Gas System Cascade Analysis (GASCA) based on Time-Based Pinch Analysis (TBPA) principle. In additional, there are 4 sub-objectives in this study which is to determine the optimal capacity (energy equivalent) of anaerobic digest...
