【摘要】 建立了变压吸附制氢均压过程的一维瞬态模型,对均压过程系统的压力和速度进行了计算分析。计算结果显示,系统的压力降呈非对称分布,低压侧的压力降大于高压侧的压力降,部分均压步骤中均压阀的压力降占到系统压力降的40%;均压时低压侧的速度大于高压侧的速度,且均压靠后步骤速度大于均压靠前步骤的速度。更多还原

【Abstract】 The article constituted the model of the pressure equalizing process of PSA-H₂ by 1D transient hydrodynamics,simulated the pressure equalizing process. The simulating result indicated that the pressure drop is asymmetric,the pressure drop is bigger and the velocity is higher in low-pressure side,the pressure drop of the valves accounted for 40% in some pressure equalization process.更多还原
