以实验室搭建的双塔变压吸附装置为基础,以Aspen Adsorption为操作平台,通过拟合相关参数,搭建了变压吸附装置富集分离煤矿乏风瓦斯的仿真模型,探究吸附时间与解吸时间对解吸气甲烷浓度的影响。结果表明,仿真模拟能较好地模拟实验情况,可以利用Aspen Adsorption辅助设计变压吸附富集分离煤矿乏风瓦斯,为气体分离提供理论与实际指导意见,节省资源与能源。 Based on the twin-tower pressure swing adsorption unit built in laboratory and using Aspen Adsorption as the operating platform, a simulation model of enrichment and separation of coal-mine gas was established by fitting the relevant parameters. The adsorption time and desorption time Impact on Desorbed Methane Concentration. The results show that the simulation can better simulate the experimental conditions, and the Aspen Adsorption-assisted design of pressure swing adsorption can be used to enrich and separate the gas from the coal mine. This can provide theoretical and practical guidance for gas separation and save resources and energy.
