Abstract

Abstract: As one of the important methods of hydrate research, experimental study using hydrate flow loops has attracted many researchers both at home and abroad for its simulation of hydrate formation, flow and blockage in pipeline transportation system. The main design parameters and experimental process of 11 hydrate experimental flow loops were introduced, including Archimede flow loop and IFP-Lyre flow loop in France, ExxonMobil flow loop and FAL flow loop of University of Tulsa in America, Hytra flow loop in Australia, NTNU flow loop, SINTEF flow loop and Petreco A/S high-pressure wheel loop in Norway and hydrate experimental flow loop of Guangzhou Energy Institute, CUPB experimental flow loop of Chemical Engineering and CUPB experimental flow loop of Petroleum Storage and Transportation Engineering in China. The research progress and main achievements based on these 11 hydrate experimental flow loops were summarized from four aspects including researches of hydrate formation in flowing system, hydrate slurry flow characteristics, hydrate plugging mechanism & risk control,and hydrate particle agglomeration & particle size distribution, respectively. The design ideas and references were provided for design of experimental flow loops with special functions. The future hydrate research using experimental flow loops should combine the macroscopic experimental data analysis with the microscopic methods,optimize experimental scheme and clarify the experimental objective to obtain the intrinsic mechanism of the relative fundamental research about hydrate.
