油水体系内水合物的生成:温度、压力和搅拌速率影响
Hydrate formation in oil-water systems: investigations of the influences of temperature, pressure and rotation rate
摘要
Abstract
Hydrate formation in pipelines poses a great threat to pipeline flow assurance. To investigate the characteristics of hydrate formation in oil-water systems, a high-pressure cell equipped with visual windows was used where a series of hydrate formation experiments were performed from natural gas +diesel oil + water systems at different temperatures, pressures and rotation rates. According to the temperature and pressure profiles in test experiments, the processes of hydrate formation under two kinds of experimental procedures were analyzed first. Then, based on the experimental phenomena observed through the visual windows, the influences of temperature, pressure and rotation rate on the places of hydrate formation and distribution, hydrate morphologies and hydrate morphological evolvements were investigated. Hydrate agglomeration, hydrate deposition and hydrate film growth on the wall were observed in the experiments. In addition, the influences of temperature, pressure and rotation rate on the kinetic parameters of hydrate formation such as induction time, hydrate film growth rate and gas consumption rate were also studied. The results and conclusions in this paper can provide theoretical supports for the development of hydrate management strategies in oil and gas pipelines.关键词
