管道中天然气水合物的预测

摘要

管道中天然气水合物的预测是为了找到天然气水合物生成条件，以便及早的发现水合物的生成，防止水合物聚集堵塞管道，造成不必要的经济损失与安全事故。介绍了图解法、相平衡常数法、热力学统计法、预测模型，并重点介绍了预测模型如VDW-P型天然气水合物预测模型、Chen-Guo预测模型、含抑制剂体系的水合物预测模型等，以期为今后的研究提供参考。%The prediction of gas hydrate in pipeline is to find gas hydrate formation conditions, which is helpful to earlier find hydrate formation to prevent hydrate from gathering to block pipeline which would cause unnecessary economic losses and safety accident. In this paper, graphical method, phase equilibrium constant method, thermodynamics and statistical method were introduced as well as prediction model, such as VDW-P-type gas hydrate prediction model, Chen-Guo predictive model, hydrate prediction model containing inhibitor system.
