“…Hydrogen sulfide (H 2 S) is the main sulfur pollutant in fuel gasses, where gases 39 exceeding 4 ppm of H 2 S are considered as sour gas. 1 Besides H 2 S, volatile organic sulfur 40 compounds (VOSC's) can be present in sour gasses, which next to their negative 41 environmental effects, are also known for their toxic and corrosive effects and obnoxious 42 smell. 2 43 Treatment of sour gas streams can be achieved by applying biological desulfurization 44 processes.…”

Bioremoval of H2S from gas streams became popular in recent years because of high process efficiency and low operational costs. To expand the scope of these processes to gas streams containing volatile organic sulfur compounds, like thiols, it is necessary to provide new insights into their impact on overall biodesulfurization process. Published data on the effect of thiols on biodesulfurization processes are scarce. In this study, we investigated the effect of methanethiol on the selectivity for sulfur production in a bioreactor integrated with a gas absorber. This is the first time that the inhibition of biological sulfur formation by methanethiol is investigated. In our reactor system, inhibition of sulfur production started to occur at a methanethiol loading rate of 0.3 mmol L(-1) d(-1). The experimental results were also described by a mathematical model that includes recent findings on the mode of biomass inhibition by methanethiol. We also found that the negative effect of methanethiol can be mitigated by lowering the salinity of the bioreactor medium. Furthermore, we developed a novel approach to measure the biological activity by sulfide measurements using UV-spectrophotometry. On the basis of this measurement method, it is possible to accurately estimate the unknown kinetic parameters in the mathematical model.

“…The main advantage of ANN over existing approaches is the capability of learning and generalizing data, fault tolerance and inherent contextual information processing in addition to fast computation potential. Such characteristics make them perfect candidates for applications where the complexity of the data or task demands high computational costs (Adib et al, 2013b;Haghbakhsh et al, 2013).…”

“…Thus, urgent solutions are needed to deal with high content of H 2 S. H 2 S removal is the most common way to deal with the acid gas reservoirs (Zhang and Wood, 2015). Additionally, some absorption methods were proposed for H 2 S removal (Abdulrahman and Sebastine, 2013;Adib et al, 2013;Al-Lagtah et al, 2015;Banat et al, 2014). This is also the reason why more than 50% acid gas removal technologies apply the aqueous solutions of alkanolamines.…”

To meet with the energy strategy, some natural gas reservoirs in Ordos Basin are planned to use as gas storages. However, most of the gas reservoirs have high content of H 2 S. If they were operated without parameters optimization, it would put reservoir engineers as well as the environment at rick. Thus, optimization of injection and production parameters of these sour gas storages is urgently needed.In the paper, using numerical method, the movement mechanism of H 2 S is studied. With the sensitivity analysis, the effects of some critical factors on H 2 S mole fraction in produced gas are investigated including ultimate recovery factor, injection rate, production rate, and injection-production rate ratio. Based on the results of the sensitivity analysis, optimal injection-production parameters are selected for a gas storage S24 in Ordos Basin.The results show that the H 2 S mole fraction in produced gas decreases as the injection-production cycle number increases. When the cycle number reaches 5, the H 2 S mole fraction is relatively stable. Additionally, the H 2 S mole fraction in produced gas hinges heavily on ultimate recovery factor, injection rate, production rate, and the injection-production rate ratio. The decrease amplitude of H 2 S mole fraction increases as ultimate recovery factor, injection rate, and injection-production rate ratio increase; it decreases as the production rate increases. Numerical results show that after 4 cycles of the operation with the optimal parameters, the produced natural gas from S24 gas storage can reach the quality standard II of commercial natural gas, which is safe for humans and environment.This study provides us with key technical references for operation of the sour gas storages to ease the contradiction between energy supply and demand. 2OTC-26686-MS
