Brief Explanation of Biogas Purification & Bottling Plant Working:
The world at present is caught between twin crises caused by the alarming increase in petroleum fuel consumption and the rapid degradation of the environment due to the combustion of fossil fuels. Internal combustion engines, which have become an integral part of present day life style, are the worst victims of this emerging energy-environment problem. Under such circumstances, it has become essential to evolve some alternative renewable clean fuels as substitute to the petroleum fuels. Several of such fuels such as Compressed Natural Gas (CNG), Biogas, Liquefied Petroleum Gas, Producer Gas, Biodiesel, Ethanol, Methanol, Hydrogen and Dimethyl Ether (DME) etc are being investigated for long term application.
At present the Indian economy is improving at a much faster rate. It is also well-known that the Indian economy is dependent on a complex energy mix. Transport sector has also got a giant share in the country’s total energy consumption. In the existing scenario, coal and petroleum products occupy the central place in the country’s overall energy mix. Apart from the starvation of fossil fuels, it is the rapid rate of environmental degradation caused due to combustion of petroleum-based fuels that needs immediate attention.
Biogas is an important alternative source of energy and main sources of Biogas production are animal dung, human excreta, poultry waste, kitchen & mandi waste, agriculture waste, municipal solid and liquid waste, waste water and various industrial waste such as pulp and paper mill waste, sugar mill waste, leather industry waste etc. From the above sources, total biogas production potential in India is 130 x 109 m3/year. It is estimated that total Biogas production potential in India can replace 52 x 109 liter/year of petroleum fuel/annum. There is large scope of developing decentralized biogas refineries and setting up biogas enrichment and bottling system as commercially viable biogas filling stations in India. These will reduce CO2 and methane emission in the environment. Basis of Design
The Biogas-Fertilizer Plant (or Bio-refinery Plant) is designed to produce Enriched Biogas/Bio-CNG/CBG (CH4 > 90%, H2S < 50 PPM, H2O (Moisture) < 0.02 gm/m3 and CO2 + N2 + O2 + other gases < 5%) and Bio-Fertilizer from Cow/Cattle Dung.
•Cattle dung – 10 MT (Ten Metric Ton i.e. Ten
Thousand kg i.e. 10 Ton)/day
•Normal Water and Recycled Water from the Plant – 10
•Biogas – 400 cum/day
•Bio-Fertilizer – 3.5 MT/day
•Bio-Fertilizer-Liquid (maximum 5 MT) is to be generated as per demand. It can be also used as a bio- pesticide.
