Joint Workshop on Clean Coal Technologies

A two day IIT Delhi-Washington University in St Louis WUStL-IIT Bombay joint workshop in the institute, held deliberations and explored the research in the fields of energy and coal, identify knowledge gaps and potential areas of collaborative research. A proposal was mooted for a joint consortium for clean coal utilization.

During the inaugural session on June 12, brief presentations were made on WUStL and IIT Delhi followed by presentations from the Heads of some departments at IIT Delhi. The session on the first day had broad ranging discussions and presentations on clean coal related research at IIT Delhi and IIT Bombay. There were also deliberations on the technology requirements and various opportunities for collaborations.

The workshop concluded with a consensus to have a consortium with definite targets. The consortium will have a 50 percent pitching from the industry. The fundamental challenges were identified and the experts outlined the way forward.

Technical landscape

The second day of the workshop treaded through technical sessions dotted with beautiful presentations in which experts from the three institutes.

Scott Hume, Principal Technical Leader—EPRI Advanced Generation enlightened the gathering on the most recent supercritical coal deployments in the US, their steam cycle particulars and strategies applied to reduce mercury emissions to meet US requiements.

R R Sonde, Executive Vice President, Thermax Limited spoke on –‘Is Methanol an Option for Securing India’s Energy?’. The talk covered all the aspects on the development needs, speed in bringing activities related to scale up to large scale methanol plants and the need for collaboration.

Jay Turner from the Department of Energy, Environment and Chemical Engineering Washington University in St Louis , USA gave a stimulating presentation on using observational air quality data to assess industrial emission source impacts. D K Sharma, from the Center for Energy Studies at IIT Delhi in his presentation said that further research work was required to make the process of organo-refining of coals cost effective by increasing the recovery of solvents and by the use of solar energy.

Sanjay Mahajani from the Department of Chemical Engineering IIT Bombay summarized the major contributions and significance of experimental and studies done at IIT Bombay.

Shantanu Roy from the Department of Chemical Engineering, IIT Delhi gave an enlightening presentation on –Hydrodynamic Behaviour of Coal and Bottom Ash Mixtures in a Fluidized Bed Gasifier. A three dimensional transient CFD model was set up to predict the dynamic and time-averaged profiles of coal and ash concentrations. The presentation also showed the feasibility of computationally intensive DEM calculations for coal fluidized systems and the benefits that accrue from it.

Suddhasatwa Basu from the Department of Chemical Engineering, IIT Delhi gave a stimulating talk on conversion of carbon dioxide to chemical fuel by electrochemical and photoelectrochemical pathways. His study proposed a way to fix the problem of Global Warming in a sustainable way using sunlight to convert carbon dioxide into useful fuels.
