Pratham Arora’s Defense Viva

Pratham Arora, a research scholar from the batch of June 2011 has successfully passed his defense viva on 23 March 2017.

Pratham conducted a techno-economic evaluation of biomass gasification for ammonia production using multi-scale modelling. Ammonia is a bulk chemical produced for agriculture and mining industry. Currently, ammonia is produced using established chemical processes on a large scale, which consume fossil fuels. These fossil fuel powered processes are responsible for greenhouse gas emissions, contributing to the global warming. Pratham’s work highlights the techno-economic advantages of small scale ammonia plants powered by biomass feedstock. The biomass feedstocks studied include wood, straw pellets, and bagasse which are available abundantly from agricultural waste. The use of biomass as potential feedstock can help in neutralizing the carbon footprint of the production. Pratham used Computational Fluid Dynamics (CFD) methods to simulate biomass gasifiers, and proposed a compartment model for ammonia production process. The outputs of the simulation were used to perform Life Cycle Costing and Life Cycle Analysis; which were further optimized by tuning the process parameters.

“The analysis will provide decision makers with consistent and comparable data to objectively judge the viability of the proposed biomass-to-ammonia process. Greening of such industrial processes would lead to sustainable production of bulk commodities as well as reduce the burden of greenhouse gases towards climate change”, says Pratham.

Pratham was jointly guided by Prof. Sanjay Mahajani (IIT Bombay), Prof. Andrew Hoadley (Monash University) and Dr. Greg Rigby (Orica).

‘The presentation was excellent and the efforts were significant. Pratham, you did a good job! Keep it up!’ said Prof. Mahajani.

‘Well done Pratham, your presentation was very clear, even in Melbourne Australia and you responded very well to all the questions. A very successful end to your studies at the IITB-Monash academy ’- Prof. Andrew Hoadley.

Pratham is working in The Enery and Resources Institute, New Delhi.

Congratulations Pratham and wish you all the best!
