Abstract

The operation of a continuous countercurrent adsorption system is modelled and optimized. The objective is to maximize the recovery of the less strongly adsorbed species in the raffinate for a specified purity of the product. The optimization is carried out for a system with linear and non-linear isotherms. The optimization results indicate that the optimum values of parameters are significantly different for linear and non-linear isotherms. An optimal choice of operating variables corresponding to a compromise between recovery and purity is also suggested.

连续逆流吸附系统的优化
对连续逆流吸附系统的运行进行了模拟和优化。目的是在指定纯度的产品中,最大限度地回收萃余液中吸附较弱的物质。对具有线性和非线性等温线的系统进行了优化。优化结果表明,在线性等温线和非线性等温线条件下,各参数的最优值存在显著差异。同时提出了在回收率和纯度之间折衷的操作变量的最佳选择。
