变压吸附过程数学模型及其应用

Pressure Swing Adsorption Models And Its Applications

从基本假设、吸附平衡、传质模型、控制方程等方面分析了变压吸附过程的数学模型的构成。从传质模型来区分,PSA数学模型主要有平衡模型、线性推动力模型和孔扩散模型。不同的数学模型具有各自的优缺点,适用不同的PSA分离过程。在建模过程中,应该选用既能反映实际过程又能尽量简化的模型。

This paper analyses the aspects of the assumptions, equilibrium relations, mass transfer models, the control equations, and boundary and initial conditions for a PSA mathematical modeL The three different models are classified according to the mass transfer models. It is necessary to choose a proper model for specialized PSA process.
