通过实验研究了冰点以下天然气水合物的生成反应中压力、温度及冰粒大小等的影响,并研究了过冷和过压在水合物生成中的作用。研究结果表明,压力越高,温度越低,冰粒越小越有利于水合物的生成,并且过冷及过压程度和过压时间均促进水合物的生成。文中还得出衡量反应进行程度的天然气水合物含气率随反应进行时间的关系曲线。
The effects of pressure, temperature and ice particle size on the formation reaction of natural gas hydrate below freezing point were studied experimentally, and the effects of supercooling and overpressure on hydrate formation were also studied. The results show that the higher the pressure is, the lower the temperature is, the smaller ice particles are more conducive to the formation of hydrates, and the overcooling and overpressure and the overpressure time all promote the hydrate formation. In the paper, we also get the curve of the gas content of natural gas hydrate measured with the reaction time.
