Experimental Investigation on Low-Doses of Guar Gum As An Eco-Friendly Kinetic Inhibitor For Carbon Dioxide Gas Hydrate

The kinetic of co2 hydrate formation in the presence of a natural edible polymer named guar gum was investigated in this work# regarding the industrial condition and affordability, the aim was to test guar gum at very low concentrations# 0#0125wt%, 0#025wt%, 0#05wt%, and 0#1wt% were the chosen concentrations# at 0#05wt% which was the best-resulted concentration, the inhibition rate of the co2 hydrate formation was increased by 287% and the induction time by 453%# in other words, guar gum at 0#05wt% increased the induction time from 52 min to 288 min and the total time of gas uptake from 4#7 hr to 18#2 hr# therefore, based on the obtained results, guar gum can be a promising khi at a very low concentration#
