Study of Ionic Liquid as Low Dosage Hydrate Inhibitor

This report constitutes of study of ionic liquid as low dosage hydrate inhibitor.
The objectives of this project are to screen, to test the performance and investigate
ionic liquids compatibility as low density hydrate inhibitor candidates. This study
focused on experimental measurement to obtain fundamental thermodynamic
behavior of methane hydrate and the kinetic of formation of methane hydrate
systems. This measurement is essential to analyze the performance of ionic liquid
towards inhibiting hydrate formation. In this work , three concentrations for each
ionic liquid have been studied at I wt%, 0.5 wt% and 0.1 wt%. EMIMCI and
OHC1MIMCJ are two ionic liquids that have been screened and tested in order to
study their performance. This measurement has been measured with Hydreval, which
is one type of PVT equipments. All the data obtained ti·om the experiment were
recorded by data acquisition system. Significant gas consumption reduction has been
observed in the presence of ionic liquids. However, the result shows insignificant
thermodynamic etlect toward hydmte formation for binary system of methane and
water.
