Abstract
The utilization of renewable fuels to substitute fossil fuels has been attracting attention due to the mitigation of environmental issues, especially those associated with climate change and global warning. Microalgae are able to produce biodiesel and sequestrate carbon dioxide from atmosphere. This work evaluates the five phases of biodiesel production from Chrorella sp: algae cultivation, oil extraction, transesterification, biodiesel purification, and glycerin separation/methanol recovery. The first law of thermodynamics is applied to establish energy balances, and the analysis includes the distillation columns as well. The results obtained herein are compared with literature data. The high energy demands of the dryers and distillation process are disadvantageous. Understanding the degradation of energy can help improve the biodiesel production process.
