CH4/C2H6 gas hydrate interparticle interactions in the presence of anti-agglomerants and salinity

Gas hydrate interparticle cohesive forces are essential to evaluate hydrate interfacial properties and determine the hydrate particle agglomeration behavior. In this study, a technique was developed in a modified high-pressure micromechanical force (HP-MMF) apparatus that enables hydrate anti-agglomerants (AAs) to be evaluated at an interfacial level under deepwater petroleum flowline conditions of high pressure and low temperature in a liquid hydrocarbon-dominated system. The hydrate cohesive force was found to decrease from the baseline (23.5 ± 2.5 mN m−1) to a non-measurable force value (
