MANTILLA GONZALEZ, Juan Miguel; DUQUE DAZA, Carlos Alberto  and  GALEANO URUENA, Carlos Humberto. Preliminary design and economical study of a biogas production-plant using cow manure. Ing. Investig. [online]. 2007, vol.27, n.3, pp.133-142. ISSN 0120-5609.

This article presents considerations and results from designing a large-scale biogas production-plant using cow manure. The so designed plant capacity allowed processing the dung from 1,300 cows, producing 500 kW of electrical energy from operating a generator which works on a mixture of diesel and biogas fuel. The design included sizing the cowsheds, the manure-collecting systems, transporting the dung, the digester, the effluent tank and the biogas treatment system. An economic study was also done, concluding that project was viable and the importance of the cost of diesel evolving for determining return on investment time.

Keywords : biogas; biogas production-plant; cow manure; economical evaluation; plug flow digester.
