VYAPAR Model
Biogas produced in anaerobic digester consists of Moisture, Carbon dioxide, Hydrogen sulphide (Impurities) and Methane gas. Due to the presence of impurities Biogas becomes a very low calorific value fuel and hence finds a very limited application even though it is cheap and easily available. Biogas need to be purified to remove the above impurities. The upgraded biogas is an economical, renewable and an eco-friendly fuel.
Versatile Yet Advanced Profit, Avail & Revenue generating model provides commercially viable BioCBG (Bio-Compressed Biogas) and BioManure.
VYAPAR model is a commercial model with payback of 4-5 years and RoI of upto 16%. For this model variety of biodegradable waste material like, cow dung, press mud, baggase, agricultural residue, poultry droppings, industrial waste, food waste etc. can be efficiently utilized.
On the basis of on–field experience, survey of the existing BioCNG unit, feedback of the operation team of various plants, suggestions of the plant owner, reviewing the policies of Govt. of India, KOSHISH has developed an innovative and cost effective model to minimise the capital and operational cost of the unit. While developing the above model experts consider:
1. Innovative designing of digester and gas holder as per available feed material and geography of the region.
2. Upto 30% less electricity consumption that other plant models due to usage of minimum machinery.
3. No recurring material costs in upgradation unit.
4. Less than 5% methane loss during upgradation in comparison to other models (such as PSA) where losses are upto 30%.
5. Innovative solutions to handle the digested manure with minimum handling and storage capacity.
Since, there can’t be a general model for BioCNG unit. Size, type and design of the plant vary case to case. Some of the factors considered while detail designing of the plant:
1. Geographical conditions of the region including soil structure and ground water table.
2. Climatic conditions as rate of biogas production is highly dependent on the atmospheric temperature region.
3. Type and quantity of the available waste, as production of the biogas is subjected to the type of raw material used and its quantity.
4. Availability of market and well-connected road network of BioCNG and BioManure.
