Study of the influence of biogas cleaning on the operational features of the biogas engine


Joaquin Reina Herdz

WWTPs are large consumers of energy, as a result of anaerobic digestion of the sludge coming from wastewater treatment is produced biogas, which by its concentration in methane (CH4) can be used as biofuel to produce energy and in this way meet the necessity of the own plant. Currently, the use of biogas generated in the WWTP is affected by the appearance of compounds, such as siloxanes and hydrogen sulfide (H2S) mainly and to a lesser extent by the appearance of hydrocarbons of different types. Another topic of interest in the energy generation from renewable fuels is related to the exhaust gases and the effect that it can have on the environment and people. BTS-MPdry technology for biogas cleaning is a multipurpose plant. This two-stage account: one for moisture reduction via cooling-condensation and the other adsorption on activated carbon (CA). For the development of this work, different types of operation tests were carried out with a view to evaluating, on the one hand, the effectiveness of cleaning technology in terms of the elimination of different harmful components of biogas, including moisture (H2O), hydrogen sulfide (H2S) and siloxanes, on the other hand, its influence on the benefits of the cogeneration system. Based on the result in this study it’s clear that an adequate biogas cleaning is needed to get a good performance of the CHP and in the quality of the exhaust gas emitted to the atmosphere.
