Effects of shear loading rate on tetrahydrofuran Hydrate Adhesion strength for enhanced flow assurance

Clathrate Hydrate-Solid Surface Adhesive Shear Strength Measurements on Carbon Steel Surfaces

“…Hydrophobicity of a surface was shown to be negatively correlated with the adhesive shear strength of the hydrate/solid interface, with most of the work focused on solid surfaces which have been coated with a hydrophobic material, with the objective of reducing the hydrate/solid adhesive shear strength. , Recent literature has explored how substrate characteristics (in particular, stiffness as quantified via elastic modulus) affect the relationship between applied stress rate and the hydrate/substrate adhesion strength. Such work provides further motivation for studying the hydrate/substrate interface via the lens of adhesion measurements. , Push-off experiments conducted on hydrophobic coated glass substrates have showed a nonlinear association between the wettability of the substrate and the hydrate/solid adhesion strength . There is limited literature currently available on the hydrate/surface interface for more wettable surfaces, especially using larger scale experiments.…”
