“…5 Membrane separation is a hot topic of research; however, there is still a distance to industrial application due to the poor selectivity and unsatisfactory working life of available membranes. 6,7 PSA is also a young separation technology since it did not appear in industry Correspondence concerning this article should be addressed to L. Zhou at zhouli@tju.edu.cn. until the 1970s.…”

A PSA cycle complemented with CO 2 displacement was studied for enriching coalbed methane (CBM). The column was first pressurized to the adsorption pressure with feed gas, and then N 2 was produced at column top in step 2. The feed gas switched to CO 2 at the end of step 2, and the adsorbed CH 4 was displaced and pushed to column top by CO 2 becoming the second column-top product in step 3. The CO 2 stream was shut off before it broke through the sorption bed. Then bed regeneration followed. A series of CH 4 /N 2 mixtures containing 17.62 to 51.33% CH 4 was used for feed gas. It was experimentally shown that the product concentration was higher than 90%, and methane recovery was higher than 98% even for the feed of low-methane concentration. Displacement at ambient pressure was shown more efficient than the displacement at adsorption pressure for the enrichment.

Membrane Separation Polymer Ionic liquidIntegrated system a b s t r a c t Many types of membranes are available to enrich hydrogen. Nevertheless, there are some with special potential for biohydrogen purification such as the non-porous, polymeric and ionic liquid based membranes. The attractiveness of these membranes comes from the fact that they can be employed nearly under the conditions where biohydrogen formation taking place. Therefore, they appear as promising candidates to be coupled with hydrogen producing bioreactors and hence giving the chance for in situ biohydrogen concentration.It is known that the feasibility and efficiency of membrane technology e beside material selection and module design e significantly depend on the separation circumstances.Thus, the operation of membranes is a key issue and the most important factors to be considered for gas purification are the composition of gas to be separated, the pressure and temperature applied. The scope of this study is to give a comprehensive overview on the recent applications of non-porous, polymeric and ionic liquid supported membranes for biohydrogen recovery, placing emphasis on the operational conditions affecting membrane's behavior and performance. Furthermore, a novel concept for integrated biohydrogen production and purification using gas separation membranes is demonstrated and discussed.

“…After the NG is dried and sent to Scrubber for heavy hydrocarbon removal, it is directed to nitrogen removal unit (NRU) to separate excess nitrogen. There are different methods to remove nitrogen from NG [22][23][24]. For NRU units in the simulation, it is assumed that 75% of nitrogen from NRU-feed is removed to fuel gas stream coming out of the NRU, and 1.3% of methane from the feed is lost in the fuel gas stream.…”
