“…It has been reported that the addition of elemental S to manure samples rich in organic carbon (e.g., poultry manure) during the preparation of sulpho-compost results in the release of H 2 S, especially under anaerobic conditions (Mahimairaja et al 1994). Hydrogen sulphide is a colourless gas with a characteristic "rotten egg" smell and a low detection threshold of 5 ppb (Busca & Pistarino 2003). The safety of workers handling stored manures should be seriously considered and protected, as H 2 S could be emitted at high concentrations when manure is taken from anaerobic storage and applied onto fields.…”

“…Some of the compounds (e.g., methane and nitrous oxide) emitted to the atmosphere are deleterious to the ozone layer and are implicated in the greenhouse effect (Clemens & Ahlgrimm 2001). These compounds may also pose environmental and health hazards due to their odorous nature and possible toxicity at high concentrations (Busca & Pistarino 2003). The most environmentally significant odorous compounds emitted from livestock manure include hydrogen sulphide (H 2 S) and ammonia (NH 3 ), because of their high concentrations and their low odour thresholds (O'Neill & Phillips 1992).…”

Winter management practices involving the use of stand-off pads to reduce problems due to cows grazing on wet soils may require storage of cow manure for extended periods prior to field application. Gaseous losses of nitrogen (N) and sulphur (S) from stored cow manure can be considerable, and these gases are offensive and undesirable. Laboratory incubation studies were conducted to measure gaseous loss of ammonia (NH 3 ) and hydrogen sulphide (H 2 S) from stored cow manure under aerobic and anaerobic conditions. The potential of adding a range of natural materials, including soil, untreated pine bark, sawdust and wood savings, to the manure to reduce these gaseous emissions was investigated. Aerobic incubation of manure resulted in a higher emission of NH 3 than anaerobic incubation, while anaerobic incubation resulted in higher emissions of H 2 S. The effectiveness of natural materials in reducing losses of NH 3 was investigated under anaerobic conditions, and pine bark was found to be the most effective. However, all materials reduced NH 3 to some degree. Therefore, the addition of natural materials, such as pine bark and soil, as amendments to cow manure during storage offers potential for reducing emissions of NH 3 and H 2 S.

“…Absorption or gas-liquid mass transfer is widely used in environmental engineering for pollutant removal [1][2][3][4]. This unit operation involves pollutant transfer from the gas phase to a liquid phase and is performed in a gas-liquid contactor dedicated to provide a large interfacial area [5].…”

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.

“…Several techniques for the removal of these sulfur compounds are available and described in the literature, see for example Busca and Pistarino (2003) [2] and Normandin, Belley, Aucoin and Gagnon (2005) [3]. Among several approaches proposed to abate or at least reduce these airborne pollutants, the utilization of ferric chelate complex of trans-1,2-cyclohexanediaminetetraacetic acid (CDTA) for the oxidative scrubbing of hydrogen sulfide and methyl mercaptan in Kraft mill streams is beneficial from the standpoints of iron protection against precipitation and oxygen-mediated regenerative oxidation of the ferrous chelate CDTA.…”

Total reduced sulfurs (TRS) include hydrogen sulfide (H 2 S), methyl mercaptan (methanethiol, CH 3 SH), dimethyl sulfide (CH 3 SCH 3 ) and dimethyl disulfide (CH 3 S 2 CH 3 ) and are referred to as noncondensible gases. They are part of a well-known environmental problem afflicting pulp mills exploiting the Kraft pulp mill process. These sulfur compounds are formed in the Kraft pulping process and come in contact with different waters and liquors, contributing to the odor problems of Kraft mills. Because of their toxic and corrosive characters, they must be removed down to very low concentration levels. The olfactory threshold of TRS for human beings is four orders of magnitudes below the regulated emission level which is approximately 5-10 ppm in Canada and the US, giving rise to strict regulations in order to reduce their emissions from specific sulfate pulp process equipments. Among several approaches proposed to remove or at least reduce these airborne pollutants, the utilization of ferric chelate complex of trans-1,2-cyclohexane diaminetetraacetic acid (CDTA) for the oxidative scrubbing of hydrogen sulfide and methyl mercaptan in Kraft mill streams is beneficial from the standpoints of iron protection against precipitation and oxygen-mediated regenerative oxidation of the ferrous chelate CDTA. The remaining (unreactive) two sulfur-bearing compounds, dimethyl sulfide and dimethyl disulfide undergo only physical absorption in such solutions. The physical solubility of these four compounds in aqueous CDTA-Fe(III) alkaline solutions is therefore a crucial parameter for designing the complete scrubbing-absorption process. The aim of this review is to highlight several aspects related to the solubility of TRS compounds in Fe-chelate aqueous solutions (experimental methods, solubility dependence on temperature, chelate concentration, and solution pH).
