Effect of quenching temperature on the performance of poly(vinylidene fluoride) microporous hollow fiber membranes fabricated via thermally induced phase separation technique on the removal of CO2 from CO2-gas mixture

Stripping of CO2 from different aqueous solvents using PVDF hollow fiber membrane contacting process

“…Thermally induced phase separation (TIPS) method was used for this purpose (Rahbari-Sisakht, M. et al, 2014;Ghasem et al, 2011Ghasem et al, , 2012Ghasem et al, , 2013. The dope solution was prepared and extruded at temperature of 170 C. The spinning conditions are given in Table 2.…”

Absorption of CO 2 from natural gas using different amino acid salt solutions and regeneration using hollow fiber membrane contactors

“…The exact details of fabrication were presented and discussed in great details in our previous studies (Ghasem et al, 2012(Ghasem et al, , 2011Rahim et al, 2014). By using homemade membranes, shell and tube type modules were constructed using Perspex tube as shell (transparent) and hollow fiber membranes as tubes.…”

“…The inner surface contact angle was measured since the liquid was made to flow through the lumen side of membrane in absorption/stripping experiments. The details of contact angle measurement were discussed in details in our previous paper (Ghasem et al, 2012(Ghasem et al, , 2011Rahim et al, 2014). …”

“…1). Hollow fiber gas liquid membrane contactor as CO 2 absorber has been comprehensively studied by several researchers and exciting experimental and theoretical results have been reported (Rangwala, 1996;Kim and Yang, 2000;Atchariyawut et al, 2007;Lin et al, 2008;Mansourizadeh et al, 2010;Marzouk et al, 2010;Ghasem et al, 2012Ghasem et al, , 2013Ghasem et al, , 2011Ze and Sx, 2014;Zhang et al, 2014). Currently, efficient and effective CO 2 stripping from liquid absorbents by using membrane contactor has become the target of many researchers in the field and few experimental results have been reported (Naim et al, 2014;Michael, 2010;Khaisri et al, 2011;Mansourizadeh and Ismail, 2011;Simioni et al, 2011;Mansourizadeh, 2012;Rahbari-Sisakht et al, 2013;Rahim et al, 2014).…”

Structure and properties of PVDF membrane with PES-C addition via thermally induced phase separation process

“…Compared to NIPS method, the thermally induced phase separation (TIPS) method has more advantages as follows: the parameters controlled in TIPS process are fewer and the process can be completed more stably and continuously; membrane porosity and strength are higher. There are many literature concerning about TIPS method [1][2][3][4]. The selection of diluent used in TIPS method is essentially difficult to find blending polymers in TIPS process [17,18].…”
