Intensification of G/L absorption in microstructured falling film. Application to the treatment of chlorinated VOC’s – part I: Comparison between structured and microstructured packings in absorption devices

Jet electro-absorbers for the treatment of gaseous perchloroethylene wastes

“…These pollutants are motivating the search of systems capable to remove them efficiently, but proposed technologies were focused on the treatment in one media, gaseous media [9,10] or liquid media [11,12] and low attention has paid to the removal of unexpected VOCs generated in liquid streams because of the selected removal treatment or simple vaporization. This objective includes the development of treatment technologies capable to face the removal of pollutants with high vapor pressure contained in the gaseous streams [13].…”

A review on an electrochemically assisted-scrubbing process for environmental harmful pollutant's destruction

“…For H 2 S absorption, the co current flow was more effective than oxygen absorption, and was explained by the rate constant measurement [92]. In an advanced level, a micro falling film column was introduced for the effective absorption of gases into a liquid [93,94]. The VOCs removal efficiency of this column is quite good and a very low flow rate is sufficient to achieve high of VOC absorption.…”

Volatile organic compounds absorption in a structured packing fed with waste oils: Experimental and modeling assessments

“…Several authors studied at the laboratory scale different synthetic NAPLs for VOC absorption, especially silicone oils (Chiang et al, 2012;Darracq et al, 2010bDarracq et al, , 2010aDumont et al, 2012;Guillerm et al, 2015;Patel et al, 2016;Tatin et al, 2015), phtalates such as di-2-ethylhexylphtalate (DEHP) (Bourgois et al, 2008(Bourgois et al, , 2006, adipates such as di-2ethylhexyladipate (DEHA) (Hadjoudj et al, 2004;Mhiri et al, 2011;Monnier et al, 2010;Monnier and Falk, 2011;Vuong et al, 2009) or even ionic liquids (Camper et al, 2006;Ferguson and Scovazzo, 2007;Guihéneuf et al, 2014;Morgan et al, 2005;Quijano et al, 2011;Rodriguez Castillo et al, 2019;. To reduce the CAPEX related to synthetic NAPLs, cheaper waste oils such as mineral oils, composed of long chained alkanes (fresh and waste lubricant, biodiesel, cutting oil), have been also considered for VOC absorption (Bay et al, 2006;Lalanne et al, 2008;Ozturk and Yilmaz, 2006).…”
