Abstract of the talk

Global CO2 emission has touched ~40 billion tons of carbon dioxide per year, and despite all the talk about net zero CO2 emission, the rate of CO2 emission is expected to stay at the current level for few more years. While role of solar, wind, hydro/waves, hydrogen etc. (perhaps nuclear as well) is acknowledged, current energy need, and proposed GDP growth of developing countries could not be achieved without ensuring implementation of CCUS. CCUS is essentially a three-step process, i) Capturing or separating the CO2 from its associated gases, ii) Transporting the captured, relatively purer CO2 (from step-i) to the utilization site where part of the CO2 could be processed for its utilization, and iii) Majority of the CO2 which could not be converted (in step-ii) has to be transported and sequestered for geological timescale. Thus, amount of CO2 utilized or sequestrated is directly proportional to the amount of CO2 captured. CO2 capture technology has to become robust, and sustainable with time, this presentation would briefly explain the challenges in adaptation of this technology at larger scale.

About the Memorial Lecture Series

Prof. K. Ganapathy Ayappa Late Prof. Chetput Venkatasubban Seshadri was a distinguished Indian chemical engineer. He started his academic career as an Assistant Professor of IIT Kanpur in 1965 and later became a full professor. Prof. Seshadri was also the Head of the Chemical Engineering Department of IITK. He took on administrative position by serving as the Dean of Students Affairs at IITK. Prof. Seshadri left IITK in 1974 to join Kasturi Paper Food and Chemicals Ltd., Bangalore, where he set up India's first fodder- yeast plant. In 1976, he joined the Shri A. M. M. Murugappa Chettiar Research Center in Chennai as its founder Director. It was at this Research Center he helped develop several appropriate technologies, including Spirulina Algae. For this effort, he was awarded the prestigious Jamnalal Bajaj award for S&T for rural development in1981. Prof. Seshadri earned his Doctorate from Carnegie Mellon University, Pittsburgh & later worked as a Research Associate at Massachusetts Institute of Technology. His friends fondly remember him as someone who could mould ordinary people like a potter into good scientists. Friends, relatives & well-wishers of Late Prof. C. V. Seshadri set up Prof. C. V. Seshadri Memorial Distinguished Lecture Series under his name. The lecture Series is conducted by the Department of Chemical Engineering.
