| 摘 要： | 为保障海上终端装卸船海底热油管道安全经济运行,引入了国外始于深海油气田开发的流动保障的概念,建立了海底热油管道的水力、热力模型.为了提高计算的准确性,在建立热力模型时,采用变化的比热容进行计算,考虑了含蜡原油结晶潜热的影响;建立水力模型时,考虑了含蜡原油在管内流动的温降过程是蜡结晶的相变过程,采用了分段计算方法.同时,...

| Abstract: | To protect the safe and economical operation of marine terminal loading and unloading submarine hot oil piplines,the concept of flow assurance is introduced in this paper,and its hydraulic and thermodynamic models are established.When a hydraulic model is being established,the heat capacity varies with the temperature,so the effect of the latent heat of crystallization has to be considered.When a thermodynamic model is established,it uses the sub-calculation method.The latest technologies of flow assurance,... |
