Amino Acid Ionic Liquid As Gas Hydrate Mitigation In Subsea Pipelines: A Review
As the oil and gas industry embarks into developments which are moving deeper subsea environments to fulfill the world’s appetite of continuous energy growth. This leads to a major safety issue which is the formation of gas hydrate as they have the tendency of plugging and clogging the pipeline. The dangers associated with hydrate plugs are severe, and hydrate inhibition strategies represents huge economical costs for the operators. Most hydrates experiences found in the literature, and the corresponding prevention, concern subsea pipelines. This review paper explains on the methods for hydrate mitigation in pipelines. A qualitative research method is used which is suitable when exploring a new phenomenon. Different technologies were chosen to review which include: chemical inhibition (KHIs, THIs and LDHIs), direct heating, depressurization and water removal for ensuring the flow assurance in long pipelines. This paper reviews the mechanism, benefits and set-backs of the gas hydrate inhibitors used in natural gas flow assurance. Considering the factors, it has been known that chemical inhibition is widely used and it’s cost effective. This paper also introduces to the possible use of amino acid ionic liquid (AAIL) as gas hydrate inhibitor. According to the properties of AAIL, it is considered as “fully green” solvent.
