摘要
天然气的水合物形成温度不仅和压力有关,而且不同组分的天然气在等压下形成水合物的温度也不同,因此有必要对天然气中各主要组分与水合物形成温度之间的关系进行研究,有效地确定水合物抑制剂的用量,有利于水合物的防治工作。文章研究了乙烷、丙烷、丁烷和戊烷与天然气水合物形成温度的关系,得到了丙烷和丁烷对水合物的影响最大,而乙烷和戊烷对水合物的影响较小的结论,从而为根据天然气不同的气质组分进行水合物的防治提供了科学的依据。
Formation temperature of gas hydrate is dependent on pressure.And gas with different component may form hydrate with different temperature under isostatic pressure.Therefore,it's necessary to study the relationship between main component and formation temperature and to determine the dosage of hydrate inhibitor,at last to help controlling gas hydrate.This paper studies the relationship between formation temperature and ethane,propane,butane as well as pentane.The result illustrates that the effect of propane and butane on hydrate is the biggest whereas the effect of ethane and pentane on hydrate is smaller.Meanwhile,the paper also provides a scientific basis for studying the hydrate control based on different gas component.
