... Three plant-based polysaccharides, pectin, k-carrageenan, and guar gum, are investigated as synergists with four kinetic hydrate inhibitors (KHIs), polyvinylpyrrolidone, polyvinylcaprolactam, Luvicap55w, and HIOP. The enhancement in the hydrate inhibition performance is characterized by measuring the increase in the delay/induction time (IT) taken for hydrate nucleation and the reduction in hydrat ...

Abstract:
... A novel conjugation of guar gum with xanthate groups via facile aqueous xanthation reaction has been reported. Density of grafted xanthate on guar gum product (GG-X) is as high as 4.4%, thus GG-X is conceivably characterized and confirmed by various spectrometric, electrochemical, thermogravimetric, and microscopic methods. Complexation of GG-X with numerous borderline and soft metal ions (e.g. Fe ...
