“…One possible reason for the higher emissions of VFAs and phenol compounds in the DDGS manures is direct volatilization of these compounds from the surface crust through sublimation. Sublimation can be a significant exposure route for semivolatile compounds in the environment (Sleicher and Hopcraft, 1984; Aronson et al, 2007; Kaiser et al, 2010), especially odors from solid waste (Adams and Witherspoon, 2004). Evidence of sublimation occurring in this study is that gas concentrations of VFAs from pigs fed the CSBM diet were low, with seven of the tanks having “negative” net gas concentrations.…”

This study was conducted to determine the impact of diets containing dried distillers grains with solubles (DDGS) on emissions of odor and odorous compounds from swine manure storage. Twenty-four pigs were fed either a corn-soybean meal (CSBM) diet or a diet containing 35% DDGS over a 42-d feeding trial. Their waste was collected and transferred to individual manure storage containers. Manure from pigs fed diets containing DDGS had significantly lower odorant emissions expressed in animal units for hydrogen sulfide (HS) and ammonia (NH) ( < 0.05) compared with pigs fed the CSBM diet, but emissions of volatile fatty acids and phenolic compounds were significantly higher ( < 0.05) for manures from animals fed the DDGS diet. There was no significant difference for indole compound emissions due to the dietary treatment applied. Emissions of volatile organic compounds (VOCs) from manure accounted for less than 0.1% of carbon consumed for either diet. There were no significant differences in odor emissions for either diet as quantified with human panels or measured as the sum total of the odor activity value. Manure odors from pigs fed the CSBM diet were dominated by HS, whereas animals fed the diet containing DDGS were dominated by VOCs.

“…The dissolved H 2 S is subjected to microbial action, leading to its oxidation to elemental sulphur or sulphates [105]. This BTF technology may be considered as a mature technology which has been shown to present high H 2 S removal efficiencies of ≥99% when employed on bench, pilot, and full-scale operations [106][107][108].…”

The desulphurisation of biogas for hydrogen sulphide (H2S) removal constitutes a significant challenge in the area of biogas research. This is because the retention of H2S in biogas presents negative consequences on human health and equipment durability. The negative impacts are reflective of the potentially fatal and corrosive consequences reported when biogas containing H2S is inhaled and employed as a boiler biofuel, respectively. Recognising the importance of producing H2S-free biogas, this paper explores the current state of research in the area of desulphurisation of biogas. In the present paper, physical–chemical, biological, in-situ, and post-biogas desulphurisation strategies were extensively reviewed as the basis for providing a qualitative comparison of the strategies. Additionally, a review of the costing data combined with an analysis of the inherent data uncertainties due underlying estimation assumptions have also been undertaken to provide a basis for quantitative comparison of the desulphurisation strategies. It is anticipated that the combination of the qualitative and quantitative comparison approaches employed in assessing the desulphurisation strategies reviewed in the present paper will aid in future decisions involving the selection of the preferred biogas desulphurisation strategy to satisfy specific economic and performance-related targets.

Environmental Technologies to Treat Sulphur Pollution: Principles and Engineering

Hydrogen sulfide (H 2 S) and other volatile sulfur compounds (VSCs) are found naturally and also as a by-product of many industries, in particular wastewater treatment, waste management and some food production industries (Bentley & Chasteen, 2004; Fisher et al., 2018b; Rochat et al., 2007). VSCs are probably the most impactful odorants due to their foul smell, low odour threshold, and relative abundance in natural and industrial processes. As a result, there are numerous methodologies to appropriately assess VSCs as an odour. VSC monitoring and assessment is accomplished by a number of approaches that are partially determined by the desired outcomes. For instance, constant monitoring of known VSC emissions is possible through online sensors, such as "e-noses", which are useful for gross VSC emissions but are typically unable to provide detailed analysis. Comparatively, detailed results of VSC concentrations and speciation require a series of steps that evaluate the appropriateness of VSC capture options. From here gas chromatography (GC) separation, followed by subsequent analysis using various chemical detectors, is suitable depending on the VSCs under investigation. VSC sampling and monitoring are challenging due to their low odour thresholds and volatility. These qualities render sampling to be assessed for its capacity to appropriately store the VSCs.
