Technical and economic analysis of a large-scale biogas plant

In this thesis, a selected biogas plant has been analyzed in terms of technical and economical. Primarily, as plant inputs, quantities of biogas and methane obtained from cattle manure have been calculated in the scope of technical analysis. Subsequently, by compiling project datas, some information about plant units and mechanical equipments have been determined. Technical analysis of plant was completed by calculating quantity of electricity, heat and fermented manure as output. To determine the model of waste management of plant; annual net profit have been calculated regarding first investment cost, revenue and expenses. The plant has been analyzed by methods of net present value, internal rate of return and payback period. Payback period of plant has been calculated as 6,2 years. Net present value of plant has been calculated positive and internal rate of return is bigger than discount rate. Therefore, construction of project has been found profitable.
