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.”
