Abstract
The polytetrafluoroethylene (PTFE) hollow fiber membranes were prepared through a cold pressing method including paste extruding, stretching and sintering in this study. Membrane vacuum regeneration technology (MVR) was developed as a novel regeneration technology for regeneration of the absorbent. The membrane structures of the PTFE hollow fiber membranes were investigated. The mixture of N-methyldiethanolamine and piperazine was selected as the absorbent. The PTFE hollow fiber membranes were used for regeneration through vacuum membrane regeneration technology. The CO2 regeneration flux and regeneration ratio increased with the increase of the regeneration temperature and the CO2 loading. The regeneration pressure was negative to the regeneration flux and regeneration ratio. When the flow rate of the rich solution increased, the regeneration ratio decreased and CO2 regeneration flux increased significantly.
