| 摘 要： | 为提高天然气水合物的生产效率及储气密度,在专门设计的水合物合成实验装置上,进行了纯甲烷水合物的合成实验。实验结果表明:对于纯净甲烷水合物,压力越高,合成速率越大;但当压力大于5 MPa时,压力的提高对生成速率的影响不大。水合物合成前抽真空时间越长,生成的水合物吸收的气体量越大,表明抽真空可以排出水中溶解的气体,提高水合物的储气密度。

| Abstract: | In order to increase the production efficiency and stored gas density of natural gas hydrate,pure methane formation hydrate tests were carried out on a special designed hydrate formation apparatus.The experiment results indicate that,for pure methane hydrates,the formation rate increases with pressure,but the increase of pressure has no obvious effects on the formation rate when the pressure is higher than 5 MPa.The longer vacuuming time before the formation of hydrates results in the larger amount of gas a... |
