Abstract

The formation of gas hydrates blocks oil and gas transportation in pipelines, nevertheless sufficient comprehension of gas hydrate behavior is the key to its prolepsis. Thus this study reports the impact of three amino acids such as asparagine, threonine and aspartic acid on methane (95%) - propane (5%) hydrate formation. Based on experimental outcomes all three amino acids performed as inhibitors, aspartic acid > asparagine > threonine following the rank from most powerful kinetic inhibitor to less one. RT experiments both formed more quickly gas hydrates and had higher values in rate of hydrate formation compared to PBTU experiments indicating better gas liquid contact in radial flow experiments compared to mixed flow ones.
