Abstract
Abstract Gas hydrates are acquainted as a significant topic to the oil and gas flow assurance, as it creates pipelines occlusions. The formation of gas hydrates can create many functional issues such as: stop of production, high preservation expenditures, environmental dangers and even loss of human beings. In this work five different amino acids such as: leucine, methionine, phenylalanine, glycine and asparagine examined if they work as kinetic inhibitors on mixture gas hydrate formation. The outcomes indicated that phenylalanine, asparagine and glycine (phenylalanine>asparagine>glycine) behaved as inhibitors following the rank from most powerful to less one while leucine and methionine behaved as promoters (leucine>methionine) for both hydrate formation and induction time.
