“…But asymmetric and composite membranes are extensively applied in industries which provide good mechanical strength via a thin separation layer (Sridhar et al, 2007). Further, the asymmetric structure of membranes has better removal effect than that of the symmetric structure (Albrecht et al, 2005;Chen et al, 2011).…”

With the aggravation of the unprecedented greenhouse effect, the reduction of greenhouse gases which mainly consist of CO 2 has caught high attention by global scholars. The membrane absorption of CO 2 from the flue gas seems a promising alternative to conventional absorption methods like chemical absorption. In this article, the principles of the membrane absorption process were discussed. The research development and current status of CO 2 capture in flue gas using a hollow fiber membrane contactor were reviewed. The affecting factors included the membrane structure and material, module connection form, gas and liquid flow pattern and absorbent. Also, these factors that affected the separation performance of mass transfer processes, as well as the mass transfer coefficients and models for CO 2 absorption were critically discussed in the tube side, shell side and membrane. Also, an experiment system for CO 2 absorption in a membrane contactor was dipicted. The modeling works were validated with experimental results. Additionally, the deficiencies of present development in membrane gas absorption of acid gases and recommendations for future pilot-scale applications were proposed.

“…Typical membranes applied in membrane distillation generally possess microfiltration properties with a pore size of 0.1 -1 mm and provide a membrane thickness of 10-300 mm (Albrecht et al 2005). The mean pore diameter of the M-2 membrane was 0.96 mm, which was the largest in the three fibers.…”

Fabrication of polyvinylidene fluoride (PVDF) hydrophobic asymmetric hollow fiber membranes was studied by introducing inorganic salt LiCl and water soluble polymer polyethylene glycol (PEG) 1500, using N,N-dimethylacetamide (DMAc) as solvent and tap water as the coagulation medium. The membranes properties also were tested and characterized. It is found that the nonsolvent additive can increase membranes porosity, ether LiCl or PEG 1500. Because of the addition of PEG 1500, the PVDF membranes obtained a rough topography on the membrane surface and the contact angle of the PVDF membranes increased to 113.508 compared to 89.828 of the PVDF membranes spun without an additive. During direct contact membrane distillation (DCMD) of 0.6 M sodium chloride solution, the PVDF membranes spun with PEG 1500 as a non-solvent additive achieved higher water permeation flux compared to the membranes spun from PVDF/DMAc and PVDF/DMAC/LiCl dopes, but the latter two membranes exhibited higher salt rejection rate.
