摘要: 以膜渗透理论为基础,建立了中空纤维膜的渗透微分方程,之后以HYSYS为计算平台,结合其Spreadsheet功能,对中空纤维膜分离器调节氢碳比进行了模拟。研究中首先以富甲烷含氢气为原料气,采用建立的数学模型及模拟方法进行膜计算,通过与美国APCI公司(美国气体化工产品公司)提供的普利森(PRISM)膜的分离数据比较,验证了建立的数学模型和模拟方法的正确性。然后考察了原料侧压力、膜面积、渗透侧压力对中空纤维膜分离过程的影响。最后探讨了中空纤维膜分离器调节氢碳比的过程。结果表明,模拟结果与膜组件供应商提供的实际数据具有较好的一致性,原料侧压力、膜面积及渗透侧压力对膜分离过程具有重要影响,且可作为调节气体氢碳比的手段,为工业生产中调氢碳比的工艺设计提供理论指导。

Abstract: This paper is concerned with the HYSYS simulation of hollow fiber membrane for H/C(Hydrogen/Carbon) ratio adjustment, in which, the differential equation of the permeability was set up based on the penetration theory and solved by using the HYSYS. The simulation method was firstly validated by comparing the simulation result of membrane separation for the rich methane gas with the data offered by APCI(Air Products and Chemicals, Inc.). Then, the effect of the feed side pressure, membrane area and permeate side pressure on the membrane separation process was investigated. Subsequently, the hollow fiber membrane for H/C ratio adjustment was clarified. The results demonstrated that simulation results show good agreement with the practical data, the feed side pressure, membrane area and permeate side pressure have great influence on membrane separation process, and provide methods for H/C ratio adjustment, which providing theoretical guidance for the process design for H/C ratio adjustment.

Key words: membrane, membrane separation, H/C ratio adjustment, simulation
