2 March 2015 Dr Praveen Linga’s paper listed among Top 25 in Chemical Engineering Science by Elsevier A PAPER by Dr Praveen Linga, published in 2012, has been listed as a “Top 25 most cited paper” in Chemical Engineering Science as of 24 Feb 2015. This constitutes the top 1 per cent of more than 3500 publications in the Elsevier’s Journal of Chemical Engineering Science. The paper, entitled Enhanced rate of gas hydrate formation in a fixed bed column filled with sand compared to a stirred vessel (Volume 68, pp. 617-623), has 49 citations and is the 22nd most cited paper within the Journal. Related to gas hydrate formation pertaining to energy recovery and carbon capture, Dr Linga’s paper described the performance of two gas/liquid contact modes, evaluated in relation to the rate of gas hydrate formation. One set of experiments was conducted in a bed of silica sand, saturated with water (fixed bed column) while the other experiment was conducted in a stirred vessel for each gas/gas mixture. Both sets of experiments were conducted at a constant temperature. The results show that the rate of hydrate formation in the fixed bed column is significantly greater and thereby resulted in a higher per cent of water conversion to hydrate in lesser reaction time for all the systems studied. Dr Praveen Linga's paper on enhanced kinetics of hydrate formation, has been listed as a top 25 most cited paper. Said Dr Linga, “Silica sand is a naturally available material that has allowed the formation of gas hydrates between them (inter-particle) for millions of years in marine sediments and permafrost regions. Natural gas hydrates are now considered as a huge energy resource (carbon quantity dwarfs all the fossil fuels combined and is significantly higher than Shale gas deposits). The observed ability of enhanced kinetics of hydrate formation in sand due to inter-particle pore space in a laboratory setting spurred detailed investigations to further design and evaluate cheaper/lightweight materials for applying the hydrate technology for CO2 capture which is an ongoing activity in our lab and worldwide.” Related link: Linga Lab: http://cheed.nus.edu.sg/stf/chepl/
