Microalgae has come into limelight recently as a promising method of carbon capture conversion and utilization (CCU). Certain microalgae species, which utilize CO2 as a direct feedstock, can be used to produce biodiesel (FAME) through transesterification of lipids. Despite their inherent advantages as a 3rd generation biofuel, there is currently no means to effectively evaluate their sustainability and economic viability. Process design of the microalgae biorefinery is necessary to conduct life cycle analyses (LCA) and Techno-economic analyses (TEA), but this is challenging due to the presence of numerous technology options well as the complexity of the process from feed to fuel. In this study, the microalgae biorefinery process was designed using a superstructure-model with 10 stages. Key process parameters have been identified through a formulation of a database and their uncertainties were approximated with a min/max range. Lastly, black-box modelling of the biorefinery was conducted using the process parameters to yield mass and energy balances for upcoming LCA and TEA studies. |
