A non-polluting and renewable source of energy is obtained in a biogas plants. Under the process organic waste is converted to useful fuel. It is an excellent way of energy conversion. Automobile grade Bio-CNG can be produced from WASTE STUFF from Rural, Municipality, Fruit & Vegetable Market, and Agricultural Wastes, Food Processing Waste and any other Bio Degradable Waste. The waste is collected using special vehicles designed for transporting the wastes from nearby Farm, municipality and villages, in enclosed containers to prevent air pollution by the SPV. Cattle dung is collected from nearby villages used as inoculants. Biogas plants also produce ENRICHED ORGANIC MANURE.

ENVIRONMENTAL ASPECTS

It leads to energy security via conservation of natural resources (LPG, wood, kerosene, coal, etc.). The ENRICHED ORGANIC MANURE can be used as fertilizers. Liquid slurry is rich in micro & macro nutrients along with NPK and can be directly applied in fields. It leads to soil improvement due to high nitrogen contents. The environmental aspects of the project may be enumerated as;

a.   The project has a low water footprint, as most of the process water is recycled.

b.   The project is zero discharge and provides valuable solid and liquid fertilizers, which recycle all the macro and micronutrients back to the soil.

c.    It reduces global warming by preventing fugitive emissions of methane from organic waste streams.

d.   For all these reasons, the project is entitled to excise and VAT exemption, tax breaks and subsidies.

e.   Bio-CNG Project provides improvement in the environment, sanitation and hygiene by proper management of waste.

f.    It improves ground water quality as anaerobic digestion provides several water quality benefits.

g.   Biogas digesters can destroy more than 90% of disease causing bacteria that can otherwise enter surface water. Thus it reduces risk to human and animal health.

ADVANTAGES AND BENEFITS OF BIO-CNG:-

·       Biogas is eco-friendly fuel. Provides a non-Polluting and renewable source of energy.

·       Has a calorific value of around 6kWh/M³—this is equivalent to half a liter of diesel.

·       Larger biogas plants can generate and feed electricity into mainstream power grids.

·       Efficient way of energy conversion.

·       Saves women and children from drudgery of collection and carrying of firewood, exposure to smoke in the kitchen, and time consumed for cooking and cleaning of utensils.

·       The digested sludge is high quality organic manure, completely natural and free from harmful synthetic chemicals. It can supplement or even replace chemical fertilizers.

·       Leads to improvement in the environment, sanitation and hygiene.

·       Provides a source for decentralized power generation.

·       Leads to employment generation in the rural areas.

·       Any biodegradable matter can be used as substrate.

·       Anaerobic digestion inactivates pathogens and parasites, and is quite effective in reducing the incidence of water borne diseases.

·       Environmental benefits on a global scale: Biogas plant significantly lowers the Greenhouse effects on the earth’s atmosphere. The plant lowers methane emissions by entrapping and using it as fuel.

·       The project combines and synergizes state of art foreign technical knowhow and equipment with cost effective frugal engineering and balance of plant from INDIA.

Contrary to Solar Photo Voltaic technology that converts Solar Energy into Electricity, the present technology uses concentrated solar heat to generate steam and run a conventional ‘Rankin Cycle’ based power plant, important features of the technology are enumerated as follows.

Process Diagram: -Parabolic Trough CSP Collection, Heat Storage System Coupled with Super Critical ORC evaporator Turbo-machinery

Description: - The process of power generation is completed in two distinct cycles, first one is the Heat Collection Cycle, and other is the Power Cycle. Thus the process is known to be Binary Cycle Power Plant.

Heat Collection Cycle: - Concentrated Solar Heat is concentrated through the PTC/ LFR Fresnel solar field, and thus a suitable Heat Transfer Fluid (HTF) which is heated to high temperature and stored in adequate Heat Storage Tanks. The Heat Collection Cycle operates 8 Hr/Day.

Power Cycle: - In the evaporating heat exchangers the working fluid is evaporated and super-heated up to its super critical parameters of pressure and temperature. The said working fluid is then used to turn the Rankin Cycle based Power Plant, thus the Electricity is generated. The Power Cycle runs 24X7 therefore the regular power is made available, to achieve up to 100% PLF. 

Main Components

CSP CollectorIn present CSP system Solar irradiation is concentrated 180 times by means of the Linier Fresnel Solar Concentrators, on a receiver tube, which is situated in the common focal line of a Solar Collector Module (SCM) Trough adequate arrangement of reflector mirrors. Therefore the said vacuum receiver tube attains high temperature, and the heat is thus picked up by a suitable Thermic Oil (HTF), flowing inside the receiver tubes, and channelized there-from to the Heat Bank of the Plant to be stored at about 360-400°C) of the Heat Storage System.

Heat StorageMetallic pressure vessels are used to store heat in appropriate storage media the design capacity of the storage system is adequate enough to ensure overnight operation of the plant on full swing.  

Power Plant The Power Plant is a conventional Rankin Cycle Power Plant, in which the steam is generated in the appropriate boiler heat exchangers by utilization of the solar heat which is further used to run the Turbine and so connected Electric Generator.

Transformer and Switch Yard The Electric Power is step up and synchronized to tune with the Grid and the generated power is fed into grid line to be channelized to the point of consumption.
