Toward an Efficient Biorefining of Microalgae and Biomass Alike: a Unit Operating View on How to Mimick the Optimisation History of the Crude Oil Refining Industry

One major hindrance to biomass deployment, and one which only benefitted from an unbalanced development, is refining into the different fractions which have a market value. Indeed, most products obtained from oil refining owe to the level of sophistication and optimisation reached by energy-integrated fractioning (mostly, distillation) networks. The separation stage of microalgal and lignocellulosic biomass could be addressed by using a converging approach employing a multipurpose solvent which may be adapted by one single and simple operation to different extractions. Such a single-solvent separation approach would lend itself to scaleup to a solvent-integrated fractionation network that might help mimicking the success story of the oil refining industry.
