“…It must be noted that source term is zero everywhere except at the membrane surface [10]. In the membrane feed interface side the source term is negative, whereas it is positive in the permeate interface side.…”

“…Given this situation, the concentration variation in radial direction (or concentration polarisation phenomena) is very weak as discussed elsewhere [9][10][11][12][13]. Therefore, we assume there was negligible concentration variation in the radial direction.…”

“…Literature related to gas separation on this topic is generally limited, whilst the majority of Computational Fluid Dynamic (CFD) investigations have focused on liquid separation [8]. To date, CFD simulation has been carried out for molecular sieve silica [9,10], Pd [11] and polymeric [12] membranes. These studies showed the significant benefit of distributed-parameter simulation in modelling membrane gas separation processes, thus replacing the averaged or ''lumped'' parameter model.…”

The main aim of this work is the presentation of quantitative analysis of silica membrane for hydrogen separation from methanol steam reforming products to produce high purity hydrogen. This study uses a single stage silica membrane in three different flow patterns, namely cocurrent, countercurrent and cross flow, for separation of a typical methanol steam reforming products stream. The modeling results showed that the silica membrane presents noticeable performance to produce high purity hydrogen. In particular, by considering the stage cut, it was found that the hydrogen molar fraction in the permeate side was decreased by increasing the stage cut from 0.1 to 0.65, whereas the carbon monoxide molar fraction increased for all of the flow patterns. In addition, a similar effect was observed for membrane surface area. Moreover, the retentate side pressure effect was positive on the silica membrane performance, although the improvement of silica membrane performance was not considerable for more than a pressure gradient of 3 bar. This analysis indicated that by using single stage silica membrane, 99% hydrogen molar fraction and 0.4% carbon monoxide molar fraction in the permeate side can be achieved for a pressure gradient equal to 3 bar.
