Abstract

The generation of electricity using organic residue from animal production farms is not very well known in Brazil. Therefore, the objective of this study was to evaluate the technical feasibility of using a 30 kVA monophase generator engine set in order to generate electricity by the combustion of purified biogas. It was used three physicochemical processes for removing hydrogen sulphide, which were wet filtration (0.1 m3 H2O + 20 kg of CaO and 10 kg of charcoal); dry filtering (50 kg flat wire annealed No. 06 and 10 kg of charcoal) and filtering in series (wet filtering followed by dry filtering), fillings the filters with the same proportions. Performance of the generator engine set was evaluated as a function of operating time. Based on the results, it could be concluded that on average the filtering systems reduced emission of SO2 and CH4 of the generator engine set and maintained emission of H2S. The wet filtering with calcium hydroxide resulted in the highest theoretical and observed yields for the generator engine set set, which were 29% and 12%, respectively.
