This study examines the impact of three amino acids such as proline, methionine and tryptophan on methane (95%)–propane (5%) hydrate formation with the use of different impellers. The concentration of amino acids was 1 wt% at 24.5 bar and 2 °C. Based on experimental outcomes proline behaves as inhibitor and methionine and tryptophan perform as promoters. RT experiments both formed more quickly gas hydrates and indicated higher values in rate of hydrate formation compared to PBTU and PBTD experiments showing that in radial flow bubbles are subjected to higher shear stresses, their size are reduced, so that the contact surface is increased resulting in an improved mass transfer coefficient.
