The modeling results showed that silica membranes have a high potential for high purity (more than 99.9%) hydrogen production. The lowest amounts of compressor duty and the required total membrane area were considered as the objective functions to select the optimal design and amount of hydrogen purification.  A comparison of our simulation results of the different multistage membrane schemes showed the CRC configuration was more efficient than the other configurations. The modeling results show that that increasing the retentate side pressure from 2 to 5 bar reduced the total silica membrane area for the CRC scheme by almost 13 times (30.67 and 2.37 cm2 silica membrane area for a retentate side pressure of 2 and 5 bar, respectively).}, keywords = {Silica membrane,Hydrogen Separation,Modeling,multistage membrane schemes}, url = {https://hfe.irost.ir/article_838.html}, eprint = {https://hfe.irost.ir/article_838_369fcd2a673a50e1e5abcdf0230a54a6.pdf} }
