Techno-economic analysis of ash removal in algal biomass
Large-scale microalgae cultivation for biodiesel production is expected to be performed utilizing open air growth infrastructure which will inherently introduce ash into the system. High ash content biomass represents a significant challenge for the production of biofuel as it increases processing capital and operational costs. This study directly assesses the economic viability of pretreatment processes focused on the removal of ash from biomass grown with an algal turf scrubber (ATS) unit. An engineering process model of biofuel production was developed based on an ATS growth architecture ...
