喷雾制取天然气水合物过程的特性

考虑到水的雾化可以有效提高气-水接触面积,有助于提高水合物生产速率,设计和建造了一个半间歇式雾流强化水合物实验装置,用于探索和揭示喷雾强化天然气水合物制备过程的基本特性,包括制备水合物的形态特征,形成过程中参数的变化规律,以及系统初始压力和初始水温度对形成过程诱导时间的影响.实验结果证明,在半间歇式反应器中,喷雾强化方式可以制取天然气水合物,并能有效地缩短水合物形成的诱导时间.水合物的制备过程中,喷雾的启动会引起系统内部压力有短暂的升高.

Performance of natural gas hydrate production process in a batch reactor with water spraying

Considering the water spraying can effectively increase the contact area between gas and water and promote the hydrate production rate,a batch reactor with water spraying was built in order to experimentally investigate the forming performance of natural gas hydrate,the system's state parameters' variation and its effect on induced time of initial pressure and water temperature.The results show that the natural gas hydrates can be produced in this way,and water spraying can effectively reduce the induced time of hydrate formation.During the reaction process,the beginning of water spraying can cause the system pressure to increase temporarily.
