화학첨가제를 이용한 하이드레이트 형성 억제 효과 분석
Investigation of Inhibition Effect on Hydrate Formation by Chemical Additives
초록
In this study, the phenomena of hydrate formation and inhibition were investigated according to varying the concentrations using methanol and ethylene glycol as chemical additives. The results reveal that the used additives display better inhibition effects compared to pure water by decreasing the formation temperature and the inhibition performance of methanol is superior to that of ethylene glycol. As a conclusion, the plugging phenomena of flowline in natural gas product ion. subsea and frozen field pipelines can be predicted by examining the hydrate formation and inhibition conditions. Specifically, the results of this study can be applied to the selection of the prevention criteria and method of hydrate formation.
