Biogas as substitute fuel
Abstract
In this paper the potential of biogas generation is evaluated through cow manure. The feasibility of implementing the digester is shown using biogas as substitute fuel (LP Gas) and obtain carbon credits. It require a minimum of 200 head of cattle to implement a microturbine system with 30kW power (ISO). Power is evaluated through a simulation with local conditions and it is obtained 21.26 kW. A cogeneration system with efficiency of 45.6% is evaluated. The use of natural gas and biogas produced is compared, showing a difference of 10.5 and 1 year at the time of payback for biogas. 8 different cases were analyzed; with primary and secondary benefits like is electric power production, process heat, carbon credits and sale or consumption of biofertilizer (15.4x10power(-03) USD/kg).
