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

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

“…This is because CO 2 solubility decreases rapidly with temperature. These results were proved by several researchers (Michael, 2010;Khaisri et al, 2011;Mansourizadeh and Ismail, 2011;Rahim et al, 2014).…”

“…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). …”

“…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).…”

Carbon dioxide (CO 2 ) handling and carbon capture utilization and sequestration (CCUS) research relevant to natural gas: A collection of published research (2009–2015)

“…Permeation measurements showed a steep decline of performance (i.e., membrane selectivity) as the partial pressure of CO 2 decreased in the gas mix. Rahim et al (2014) described experiments to strip CO 2 from various aqueous solvents using a polyvinylidene fluoride (PVDF) hollow fiber membrane contactor. The experiments revealed that, regardless of the solvent involved, CO 2 stripping flux and efficiency rapidly increase with liquid temperature, pressure and initial CO 2 concentration.…”
