A methane production feasibility model for central anaerobic digesters


, : A methane production feasibility model for central anaerobic digesters. Resource Recovery & Conservation 5(4): 319-332

A mathematical model was developed for prediction of the practicability of building and operating large centrally located anaerobic digesters for producing methane gas from animal manure. The assumptions were that the manure would be collected from the feedlots and that the product gas would be supplied to an existing pipeline. The model takes account of the farm locations and calculates transportation costs for various numbers of digesters. Digester sizes for each distribution are computed and installation and operating costs are found. Revenue is then determined on the basis of methane production and fertilizer value recovery. The utility of the model is shown through an application study of farms in southwestern Ontario [Canada] where many relatively small feedlots exist. The results indicate a gas production cost of roughly $0.18/m3 ($5.00/106 ft3).
