Biogas as Renewable Energy from Organic Waste
In the next few years the energy crisis is the deficiency of fuel for the daily requirements of millions of people. Biogas is an important renewable source of energy, a source of improved organic fertilizer, a mechanism for wastage management and is a progressive technology. The main objective of biogas is to upgrade the sustainable production of renewable energy. Biogas plants are suitable to the technical abilities and economic potential of farmers. Biogas technology is extremely significant to the ecological and economic demands of the future.
A biogas plant produces energy and fertilizer. It improves hygiene and protects the environment.
The biogas plant must be a symbol of social advancement. The biogas plant must be technically progressive.The efficiency of biogas plant can be improved if properly designed. Unsatisfactory performance of biogas units occurs mostly due to planning mistakes. The effects of these mistakes may be seen immediately or after several years. Therefore careful planning is important to avoid irreversible stages. As biogas production is expensive, it should not be a temporary set up. The design of biogas plant must not be primal.
Therefore determining siting criteria is the initial step in biogas plant. The process begins with the estimation of quantitative and qualitative energy requirements of the customer. Then the biogas generating potential is calculated for the given biomass production and compared to the energy demand. Energy demand and the gas generating potential can not be determined in planning phase. Sizing of plant (digester, gasholder, etc) is the next step in the planning process.
A graphical user interface with software was developed for designing modified PAU Janta model biogas plant MATLAB R2015a. The input is given as size of biogas plant and retention time and output is shown as dimensions of different components such as mixing tank, digester, dome and outlet tank. The computed dimensions were compared with the manual calculation and results were matching as indicated by t-test at 95% confidence level. The main aim is to develop an android application which shows dimensions of the biogas plant on giving input as size of biogas plant and the retention time.
