Hollow fiber membrane contactor for hydrogen sulfide odor control

Abstract: Hollow fiber membrane modules are extensively used as gas–liquid contactors for acid gas removal from waste gas streams. Hydrogen sulfide is an important indoor and outdoor contaminant, but, given its toxicity, a limited number of experimental results have been reported for this compound. Moreover, chemical absorption has been exclusively investigated. In this study, hydrogen sulfide odor control by absorption in water thanks to a hollow fiber contactor has been studied both experimentally and theoretically. T… Show more

“…Due to the dilute concentration of H 2 S in air, conventional contactor columns have been operated using only water as the absorption solvent. The application of membrane contactors for the absorption of low H 2 S concentrations from air using water as the solvent has also been well described by Boucif et al [5].…”

“…Many works in the literature have focused on gas/liquid mass transfer occurring within HFMC, especially for CO 2 capture (Rangwala, 1996;De Montigny et al, 2006;Li and Chen, 2005;Mavroudi et al, 2006), hydrogen sulfide odor control (Boucif et al, 2008), or removal of volatile organic compounds from water/wastewater (Malek et al, 1997;Mahmud et al, 2000Mahmud et al, , 2004. Experimental works are often coupled with numerical simulations as the hydrodynamics of the liquid within narrow tubes is well-known (Gong et al, 2006;Zhang et al, 2006;Al-Marzouqi et al, 2007;Yan et al, 2007).…”

“…On the other hand, a further application considers the removal of H 2 S from air using demineralized water (pH 7) for odor control [38]. Porous polypropylene hollow fiber modules with different geometrical parameters were used in this application obtaining 89% of removal for inlet concentrations of 100 ppmv when the gas stream was circulated through the lumen and the water through the shell of the membrane contactor.…”
