Gas hydrates are recognized as a significant concern to the oil and gas flow assurance, as it generates pipelines blockages. In this research three alterative amino acids such as: glutamine, cysteine and isoleucine investigated if they work as kinetic inhibitors on methane-propane gas hydrate creation. The outcomes indicated that cysteine worked as inhibitor while isoleucine and glutamine worked as promoters (glutamine>isoleucine) for both hydrate formation and induction time. Experiments with glutamine and isoleucine have the highest value of hydrate productivity while the lowest value of hydrate productivity belongs to experiments with cysteine. From hydrodynamic behavior, radial flow experiments indicated better gas liquid contact compared to mixed flow experiments.
