摘要：
Deepwater oil and gas transportation systems play a crucial role in energy supply, but also face the challenges of hydrate generation and blockage. The study observed hydrate generation and deposition at different subcooling degrees and flow rates by using a high-pressure fully visualized recirculation pipeline. It was found that the subcooling degree has a nonlinear positive correlation with the total amount of hydrate generated. The hydrate formation at 11.7 °C subcooling was 4.5 times higher than that at 9 °C subcooling. According to the hydrate conversion rate analysis, the hydrate growth process under low subcooling conditions directly transitions from the bubble-promoting zone to the termination point of hydrate generation. Combined with the deposition state of the pipe wall and the differential pressure change curves, the risk of blockage at different subcooling levels and flow rates can be assessed. © 2024 Elsevier Ltd
