Gas hydrate formation in gas pipeline often results in blockage and shutdown of these pipeline to mitigate the problem .Gas hydrate is a crystalline structure formed from water that host a low weight gas molecule. Natural gas hydrate occurs with presence of water, gas, high pressure and low temperature. As gas production moves to deepwater, the problem becomes serious due increase in pressure drastically and sub cooling temperature. As compare to other inhibition methods chemical inhibitors highly favored due to efficiency and economical factor. There are two type chemical inhibitors available. Thermodynamic inhibitor shifts the hydrate equilibrium curve meanwhile low dosage inhibitor retards or slow down hydrate growth over time. However both inhibitors have major drawback that require serious attention. Ionic liquid (IL) have been selected as novel approach to inhibit gas hydrate formation. IL full fills criteria as dual hydrate inhibitor, thermodynamic inhibitor and kinetic inhibitor. For this experiment two of IL [OH-C2MIM]-Cl and [OH-C2MIM]-Br have been tested. The experiment is conducted using High Pressure Micro Differential Scanning Calorimetry (HPìDSC). Both ILs is tested at effective concentrations to for thermodynamic and kinetic inhibition. Experimented ILs shows promising result by shifting hydrate stability curve to lower temperature region and delays the hydrate formation.
