摘要
使用SIFSIX-3-Ni(MOF)作为吸附剂,应用Aspen adsorption软件建立双床6步工艺流程模型,对CHF3/N2混合气体变压吸附(PSA)提纯CHF3的过程进行了研究.分析了吸附压力、进料流量、吸附时间、均压时间、降压时间以及真空度等主要工艺参数对φ(CHF3)和回收率的影响,通过工艺模拟,当吸附压力1.5 bar,进料流量0.6 m3·h-1,吸附时间165 s,均压时间22 s,逆放时间95 s,真空度0.1 bar条件时,φ(CHF3)达到99％以上,回收率达到90％以上.
Abstract
The adsorption column was filled with SIFSIX-3-Ni(MOF)as the adsorbent.The purification process of CHF3 from CHF3/N2 mixture by pressure swing adsorption(PSA)was simulated by a two-bed six-step model using Aspen adsorption.The effects of adsorption pressure,feed flow rate,adsorption time,pressure equalization time,blow down time and vacuum degree on the purity and recovery of CHF3 were studied.The optimum process simulation conditions have been achieved when the adsorption pres-sure,feed flow rate,adsorption time,pressure equalization time,blow down time and vacuum degree are 1.5 bar,0.6 m3·h-1,165 s,22 s,95 s,0.1 bar,respectively.Under this condition,the purity of CHF3 is above 99％and the recovery is above 90％.
