Effect of Composite Promoting Agents on Gas Hydrate Formation

Abstract:

An experiment on effects of composite promoting agents composed of surfactants and liquid hydrocarbons on hydrate formation was conducted and hydrate formation temperature, pressure, induction time and rate with different composite promoting agent portfolios were measured. Surfactants used were sodium dodecyl sulfate (SDS), sodium dodecyl benzene sulfonate(SDBS) and 2-octyl sodium dodecyl sulfate(GC20S), and liquid hydrocarbon additives utilized were ring silane e (CP) and methyl cyclohexane (MCH). It appeared that all these combinations of composite promoting agents could promote hydrate formation. Type II and H hydrate formation conditions with composite promoting agents CP+GC20S and MCH+GC20S respectively were the mildest and the induction time was the shortest.
