基于平衡理论，建立了一个模拟多组分、非线性平衡的逆流吸附分离过程的简单模型。通过与分子筛上吸附分离芳烃C8的详细模型的比较，验证了该模型的可靠性。基于该模型，开发了一种简单而准确的优化分离装置的设计方法，在此过程中，吸附剂和脱附剂的用量最小，而萃取物和残液的富集度最大。重点放在脱附剂的作用和流体的物理状态的影响，即蒸气或液体的操作。
A simple model, based on equilibrium theory, for simulating countercurrent adsorption separation processed involving multiple components and nonlinear equilibrium has been developed. The reliability of this model has been tested by comparison with a detailed model in the context of the separation process for the aromatic fraction C8by adsorption on zeolites. Based on this model, a simple and accurate procedure has been developed for designing optimal separation units, where adsorbent and desorbent requirements are minimized while enrichments of both extract and the raffinate are maximized. The emphasis has been placed on the role of the desorbent and the effect of the physical state of the fluid, i.e. vapor or liquid phase operation.
