Abstract
In this work, the experimental investigation was performed on ethane hydrate formation in presence of noninonic surfactants consist of different molecular weight of Copolymer E.O/P.O and Lauryl alcohol ethoxylates. For this purpose, the induction time and kinetic of ethane hydrate formation have been determine at temperature of 277K and initial pressure of 21 bar in varying molecular weight of additives. The best molecular weight for increasing induction time has been identified.
