Title

Comparison of Carbon Dioxide Absorption of PVDF and PVDF-CTFE Hollow Fiber Membranes

Pages

  177-188

Abstract

 Polyvinylidene fluoride (PVDF) and poly(vinylidene fluoride--chlorotrifluoroethylene) (PVDF-CTFE) Hollow fiber membranes were fabricated via a wet phase-inversion method and the fabricated membranes were used for CO2 absorption with 1 M monoethanolamine solution in a Gas-liquid membrane contactor system. Both types of Hollow fiber membranes have a sponge-like structure close to the inner surface of the membrane and a finger-like structure close to the outer surface of the membrane but, the sponge-like structure of PVDF-CTFE membrane is thicker than PVDF membrane. The overall porosity of PVDF and PVDF-CTFE membranes were measured as 75. 49 % and 69. 51%, respectively. The critical Entry Pressure of water (CEPw) of PVDF-CTFE membrane is 9. 5 bar and CEPw of PVDF membrane is 7 bar. The contact angle of water with PVDF-CTFE Hollow fiber membrane surface is higher than PVDF membrane, which indicates higher hydrophobicity of this membrane. The maximum CO2 absorption flux of 7. 20×10-3 (mol m-2 s-1) and 4. 4×10-3 (mol m-2 s-1) at the liquid phase flow rate of 300 (ml min-1) was achieved for PVDF and PVDF-CTFE Hollow fiber membranes, respectively. The results of the long-term CO2 absorption experiment showed that the CO2 absorption flux of PVDF membrane decreased by about 85% and reached 6. 6×10-3 (mol m-2 s-1), 20 h after the beginning of the process. The CO2 absorption flux of PVDF-CTFE membrane decreased by about 15% and reached 8. 8×10-3 (mol/m2. s), 70 h after the beginning of the process.
