characteristics of Permeate Side spacers of spiral wound membrane modules
Desalination, 2013Co-Authors: C P Koutsou, A J Karabelas, T B GoudoulasAbstract:Abstract Reliable estimates of the effective lateral permeability (k) of Permeate-Side spacers of spiral wound membrane (SWM) elements are required in order to design them and simulate module and plant performance. Such permeability data are not available at present. A straightforward approach is recommended for determining k of spacers under modest pressure, which involves pressure drop measurements in a spacer-filled channel coupled with separate accurate data on the effect of normal pressure on spacer thickness. Application of this approach to typical spacers from commercial SWM modules shows that k is at the level of 2 to 3.5 × 10− 10 m2, for measured thickness 0.20 to 0.25 mm. The tested spacers exhibit modest compaction under pressure, with a tendency to approach asymptotically a minimum thickness at a pressure smaller than that prevailing in tightly wound membrane envelopes of commercial modules. Recommendations are also outlined regarding R & D directions on the selection of appropriate Permeate spacers in the context of overall optimization of SWM module design and desalination process performance.

a membrane reformer with Permeate Side combustion for co2 capture modeling and design
Energy Procedia, 2011Co-Authors: Jan Wilco Dijkstra, F Francisco Zaragoza J Martin, Jurriaan J Boon, J MeuldijkAbstract:The design of a pre-combustion natural gas fired power plant is presented, which makes use of a membrane assisted reformer with Permeate Side combustion. A detailed reactor model has been made with which the impact of the air distribution pattern is assessed. The results demonstrate that a flat air distribution pattern is sufficient for avoiding hot spots in the reactor. A system assessment shows that the concept is competitive with conventional membrane reformers in terms of system efficiency, and offers a more compact design.
