模拟移动床吸附分离技术主要用于分离沸点接近但是被吸附能力不同的混合物,生产高纯度产品。液相模拟移动床每个吸附剂床层均设置物料进、出管线。物料进、出管线的数量和位置,是模拟移动床吸附分离工艺的重要影响因素。通过计算流体力学(CFD)模拟确定了物料进、出管线的数量,以及各股物料在管线中的排列位置和进、出料顺序,并根据计算结果,对工艺进行了优化,确定了生产高纯度产品的液相模拟移动床物料进、出管线冲洗工艺。
Simulated moving bed adsorption separation technology is mainly used to separate the boiling point close to but different adsorption capacity of the mixture to produce high purity products. Liquid simulated moving bed Each adsorbent bed are set into the material into and out of the pipeline. The quantity and position of the material in and out of the pipeline are important influencing factors for the simulation of moving bed adsorption separation process. Through the CFD simulation, the quantity of material in and out of the pipeline, the arrangement position of each material in the pipeline and the discharging order were determined. Based on the calculation results, the process was optimized and the production of high Purity products of liquid phase simulation moving bed material into and out of the pipeline flushing process.
