Energy, Environmental and Economic Analysis of the Biogas Use in Cogeneration: The Wastewater Treatment Case

摘要

In this paper the authors present energy, environmental and economy evaluation for the biogas use in cogeneration. The case of a wastewater treatment plant is analyzed. For the energy balance, it uses the specific consumption for different technical processes. The reduction of the CO{sub}2 emission is calculated as a result of the biogas use. An economic assessment of the project proves that this solution is feasible. The sensitivity of the results to the biogas engine time availability and to the methane concentration is calculated.
