盐穴储气库溶腔过程盐平衡模拟

Salt Equilibrium Simulation of Leaching Process of Salt Cavity Gas Storage

为满足季节性调峰需求,保障供气安全,利用地下盐穴储气库储存天然气在国际上被广泛采用。盐穴储气库建造过程中水溶造腔是关键的一步,该过程时间跨度长且受地下盐层结构影响明显。采集实际溶腔运行数据,用Aspen对实际溶腔运行数据进行盐平衡模拟,提出了一种工程分析方法,为工程设计及生产运行提供依据。

To meet the demand of seasonal peak shaving and make sure gas supply security, underground salt cavity is widely used as natural gas storage in the world.Leaching step is the key step of cavity construction process which spans a long period and affected by underground salt layer structure.In this paper, Operation data getting from salt leaching running will be simulated for salt equilibrium with aspen plus software, and puts forward a method of engineering analysis providing basis for engineering design and production running.
