Emissions of SOx and NOx from flue gases require treatment before release into the atmosphere according to the current legislation. Physical-chemical treatments used so far are expensive and generate effluents that require further processing. This project faces the challenge of developing a comprehensive treatment process for SOx and NOx from flue gases by economical, robust and environmentally friendly biological methods that also take into account the reuse of energy and resources in process development as well as residues valorization. The proposed process is based on a multistage process including selective absorption of SOx and Nox and biological reduction-oxidation processes based on sulfate-reducing microorganisms (SRB) and sulfide-oxidizing microorganisms (SOB)that allow the recovery of elemental sulfur.
The project includes the participation of different groups in the sub-projects that provide multidisciplinary to the project. Besides the coordinator GENOCOV group from the Department of Chemical, Biological and Environmental Engineering (UAB) also involves the GAB group of the Institute of Microelectronics of Barcelona (IMB-CNM) CSIC, the GSB group of the Department of Analytical Chemistry of the UAB and the group TRAGASOL, Department of Mining Engineering and Natural Resources of the UPC.
