Abstract
The burning of natural gas and coal for electricity and heat is a great source of greenhouse gas emissions (GHG). If we do not take action now, climate change will have severe and irreversible impacts across the world. Among all of the technologies currently employed to reduce this impact, biological methods are get attention of several researchers. One of these methods is the mitigation of emissions such as CO2 and NOx using microalgae. Flue-gas emissions from fossil-fuel combustion in Power Plants can be used for microalgae cultivation, which produces a biomass with high added value and a source of animal feed, pigments, antioxidants and biofuels. However, there are many challenges to make the process feasible, e.g., development microalgae production systems and control of conditions for growth of algae. Considering the technical and financial difficulties to obtain accurate information about of microalgal growth during large-scale treatment, this research proposed an automatic monitoring process in real time, providing a more efficient process control. A prototype system is actually in developing stage for follow up the growth of microalgae in photobioreactors based on quantitative data analysis, considering planning issues and good laboratory practices. In this way, this research presents the way to embed the experience of the laboratory procedure of the monitoring of microalgae to an automated prototype applied in the field, with contributions focused on the gain of knowledge and intelligence to the process.
