Mechanism and control factors of hydrate plugging in multiphase liquid-rich pipeline flow systems: a

Frontiers in Energy   Pages 747-773 doi: 10.1007/s11708-022-0830-z

Abstract: pipelines owing to the low-temperature and high-pressure environment, although requiring the cooperation of flowrate, water content, gas-liquid ratio, and other specific factors.In addition, it summarized the influences of fluid flow and water content on the risk of hydrate blockageIn general, flow rate was implicated in the regulation of blockage risk through its characteristic toaffect sedimentation tendencies and flow patterns.
