This study investigated anionic guar gum derivatives as dual-purpose inhibitors for methane hydrate formation and metal corrosion in oil and gas pipelines. Sulfonated guar gum (SHG), phosphorylated guar gum (PGG), and guar gum grafted acrylamide (GG-g-PAM) were synthesized and evaluated for their kinetic hydrate inhibition and corrosion inhibition properties. The results demonstrated that all anionic guar gums exhibited superior inhibition effects compared to native guar gum and polyvinylpyrrolidone (PVP), with GG-g-PAM achieving the highest ma...
