Abstract: Although many studies have been conducted to investigate the hydrates formation and slurry flow during the transportation, studies on the hydrates slurry pressure drop properties using spiral flow in a loop are still almost blank. In the current work, a series of experiments about hydrate formation process and pressure drop properties were conducted in a spiral flow loop. The experiments in this work were conducted in a spiral flow loop, the loop is 97 ms, and the internal diameter is 25 mms. The experimental results showed that characteristics of hydrate formation process in a spiral loop, and the twist rate of twist tape had an influence on hydrate slurry pressure. Finally, the pressure drop model of hydrate slurry in a spiral flow loop was established, and the relative error were within 10%. This work helped to understand the effects of spiral flow on the gas hydrate formation process and slurry pressure drop, and provide an insight into the mechanism of how spiral flow affect gas transportation.
