Kinetics of (TBAF + CO2) semi-clathrate hydrate formation in the presence and absence of SDS

Abstract In this communication, the impacts of adding SDS (sodium dodecyl sulfate), TBAF (tetra-n-butylammonium fluoride) and the mixture of SDS + TBAF on the main kinetic parameters of CO2 hydrate formation (induction time, the quantity and rate of gas uptake, and storage capacity) were investigate...
