Investigation of the Flow Characteristics of Methane Hydrate Slurries with Low Flow Rates

Energies, 2017
Gas hydrate blockage in pipelines during offshore production becomes a major problem with increasing water depth. In this work, a series of experiments on gas hydrate formation in a flow loop was performed with low flow rates of 0.33, 0.66, and 0.88 m/s;
