Insights into induction time and agglomeration of methane hydrate formation in diesel oil dominated dispersed systems
Induction time and agglomeration of methane hydrate formation in dispersed systems play an important role in exploitation of natural gas hydrate, prevention of gas hydrate plug, and application of hydrate based technologies. In this work, an autoclave with particle video microscope (PVM) probe was u...
