| Abstract | Economy of India is moving at a pace due to modern industrialization with the availability of natural resources. Mainly, fossil fuels utilization in energy sector, transport sector and in industrial sectors are depleting out than rate of production. To overcome the concern about the use fossil fuels, move on to new path way to alternative energy sources. The utilization of fossil fuel resources in the transportation sector has led to show vital impact on climate change. An alternative biofuel is already available in market, but with advanced biofuels in large commercial scale can be an additive to overwhelm the fossil fuel in this crisis. Mostly, advanced biofuels, are produced using lignocellulose biomass, waste and algae and don’t compete with food crops. Pyrolysis oil a promising alternative fuel has acquired considerable study for its viable resource’s diversification and environmental benefit. And the advanced biofuels routes minimize the greenhouse gas emissions (GHG) by 60 -95 % compared to the fossil fuels. The main objective of this research study is to estimate the potential of rice husk and technical options for pyrolysis of rice husk in Andhra Pradesh. Paddy is grown in both rabi and kharif season with an area of 5.85 and 15.8 lakh hectares respectively in Andhra -Pradesh during 2016-2017. Andhra Pradesh stance 5th in India with a paddy production of 11,980 Kilo tonnes (kT) annually. Rice residues is selected as a potential feedstock to produce bio-oil or pyrolysis oil. Out of these residues rice husk is selected due to its surplus availability 1005 Kilo tonnes (kT) within in Andhra Pradesh. In this study, fast pyrolysis with downdraft circulating fluidized bed reactor at temperature 5000C, residence time 2s using rice husk as feedstock is selected from the reviewed papers. Financial analysis is calculated out for a 3ton pyrolysis plant, with feed input of 2.4 ton/hr, operation hours- 10hrs/day using the required parameters and obtained the annual income of 49.5 Million rupees (₹).Sensitivity analysis is calculated out using the financial analysis of a 3ton plant as base case and obtained the annual output with the variable low and high case parameters. However ,With the 10% variation in high case the percentage change in annual output as compared to base case of a pyrolysis plant is Price of Bio-oil (26%),Feedstock consumption rate (20%), Annual plant operation (hrs)(19.2%), Feedstock price (3.15 ₹/kg)- (5.4%).In similar, 10% variance for low case parameters the percentage change is similar but negative value. Finally, pyrolysis plants are feasible in Andhra Pradesh region with decentralization systems for production of bio-oil using rice husk. But the major challenge is government of India has not drafted out any new pyrolysis policy and the market for bio -oil or pyrolysis oil. |
