“…A data compilation is also available on the web for pure water (http://webbook.nist.gov/). For DMS and DMDS solubility in water, Iliuta and Larachi [7] provided an extensive review. According to these authors, the solubility data are quite scarce, while the experimental temperatures used differ greatly and cover a wide range.…”

“…The Henry's coefficient can be found in the literature, using the compilation of Sander or specific articles [36][37][38][39][40][41]. When the value cannot be found for a specific compound or in specific conditions, it remains possible to use some thermodynamic models which provide good accuracies [39,[42][43][44][45].…”

Absorption or gas-liquid mass transfer is a fundamental unit operation useful in many fields, particularly gas treatment (wet scrubbing). Absorption of basic or acidic compounds, even hydrophobic, in water can be achieved successfully due to the mass transfer enhancement linked to proton transfer reactions in the liquid film. The absorption rate takes this phenomenon into account through the enhancement factor E, which depends on many parameters: nature (irreversible or reversible), kinetics and stoichiometry of the reaction, reagents and products diffusion coefficients and concentrations. This article gives an overview of the enhancement factor determination for acidic and basic compounds transfer in water. Modeling is performed for three compounds of interest, hydrogen sulfide H 2 S, methyl mercaptan CH 3 SH and ammonia NH 3 , for different scenarii to assess the influence of the pH. The results demonstrate that recombination with HO -and protonation reactions are respectively the two preponderant reactions for respectively acidic and basic compounds. They enable to reach large values of the enhancement factor at appropriated pH and to reduce the mass transfer resistance in the liquid film. Furthermore, the simulations highlight that, in many cases, knowledge of the reaction kinetics is not necessary since the reaction can be considered as instantaneous compared to mass transfer.

“…Due to their partial solubility at lower pHs, the chemical removal of fetid sulfur-containing compounds requires large amounts of sodium hydroxide and water (Iliuta and Larachi 2007). Several studies have reported that, during bio-filtration methods, odorous contaminants are adsorbed from the air into the water present in the organic bed [i.e., bioactive layer (biofilm)] where they can be aerobically degraded to various end-products or incorporated into biomass (McNevin and Barford 2000).…”

There are increasing concerns over the harmful effects of the phosphate industry on human health and quality of life worldwide, including the Tunisian Chemical Group (GCT) in Sfax, which generates various malodorous gas fractions, such as hydrogen sulfide (H 2 S) and fetid mercaptans, causing nuisance to employees and local residents. Accordingly, the present study aimed to investigate the ability of an adapted microbial consortium isolated from the gas-washing wastewaters (GWWs) generated from GCT to degrade hazardous and malodorous mercaptans. A novel mesophilic bacterial strain (SH6), which was noted to display particularly high mercaptan degradation potential, was isolated from the adapted consortium growing on those GWWs and several malodorous mercaptans after enrichment on 1-dodecanethiol. The results from 16 rRNA gene sequencing and identity analysis revealed that the SH6 isolate belonged to Staphylococcus genus, with a high sequence similarity to Staphylococcus capitis (99.7 %). The SH6 strain was able to completely degrade 1-dodecanethiol, used as the sole carbon and energy source, after 72 h of incubation at 37°C and 180 rpm. A decrease in the surface tension of cell-free culture supernatants was observed during the oxidation of dodecanethiol, suggesting the production of surface-active compounds. The stain was also able to grow on other mercaptans, such as 1,8-octanedithiol and 2,3-butanedithiol, which further supports its potential candidacy for application in the bioremediation of mercaptan-contaminated sites. Overall, the findings of the present study indicate that the SH6 strain might offer promising opportunities for the development of more adapted, efficient and cost-effective bio-disodoration strategies.
