Effect of ®ber variation on the performance of cross- ̄ow hollow ®ber gas separation modules
نویسندگان
چکیده
A quantitative analysis of the effects of variable ®ber properties on the performance of a cross̄ow hollow ®ber gas separation module is presented. The effects of variations in size, permeance, and selectivity are considered. Fiber variability is detrimental to performance. The recovery and ̄ow rate of an enriched retentate stream decrease as variability increases. Some ®bers may actually stop producing product as purity increases. Additionally, performance is poorer if the permeate from all ®bers is not well mixed. The results of this work can be used to determine quality control guidelines for ®ber manufacture and evaluate process enhancements. # 1999 Elsevier Science B.V. All rights reserved.

Extraction of Zn, Mn and Co from Zn-Mn-Co-Cd-Ni containing solution using D2EHPA, CYANEX® 272 and CYANEX® 302
Effects of pH, D2EHPA, Cyanex® 302 and Cyanex® 272 on extractions of zinc, manganese and cobalt from a Zn-Mn-Co-Cd-Ni containing solution was comprehensively investigated at the room temperature. The addition of Cyanex® 302 indicated a left-shifting-effect on the extraction curve of zinc, a right-shifting-effect on the extraction curve of manganese and no effect on the extraction of cobalt. The...

This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...
متن کاملIs condensation the cause of plasma leakage in microporous hollow ®ber membrane oxygenators
Extracorporeal membrane oxygenators are comprised of large bundles of microporous hollow ®ber membranes (HFMs) across which oxygen and carbon dioxide are transferred to and from blood. Long term use of extracorporeal oxygenators is limited by plasma leakage through the pores of the HFM walls, requiring replacement of the oxygenator. Condensation of water vapor on the pore walls is thought to be...
متن کاملEffect of fiber variation on the performance of countercurrent hollow fiber gas separation modules
A theoretical and experimental study of the effects of variable fiber properties on countercurrent hollow fiber gas separation module performance is presented. Variations in ID, slow gas permeance, and selectivity are considered. Variability in any of these properties is detrimental to performance. The drop in performance increases as either property variation or product purity increase, but pe...
