Sulfur chemistry in bacterial leaching of pyrite.
In the case of pyrite bioleaching by Leptospirillum ferrooxidans, an organism without sulfur-oxidizing capacity, besides the production of tetra- and pentathionate, a considerable accumulation of elemental sulfur occurred. A similar result was obtained for chemical oxidation assays with acidic, sterile iron(III) ion-containing solutions. In the case of Thiobacillus ferrooxidans, only slight amo...
متن کاملSulfur dioxide emissions in Iran and environmental impacts of sulfur recovery plant in Tabriz Oil Refinery
Background: Combustion of fossil fuels contributes to sulfur dioxide (SO2) emissions. To deal with this issue, the government of Iran has appointed the oil refineries to upgrade their installations and produce high quality fuels. Thus, this study investigated the status of SO2 emissions in Iran and the capability of advanced technologies to control SO2 emissions. Methods: The status of SO2 em...
متن کاملSulfur Chemistry in the NCAR CCM 1 Sulfur Chemistry in the NCAR CCM : Description , Evaluation , Features and Sensitivity to
Sulfur chemistry has been incorporated in the NCAR CCM in an internally consistent manner with other parameterizations in the model. The model calculates mixing ratios of DMS, SO 2 , SO 2? 4 , and H 2 O 2 and cloud and rain water pH. Processes that control the mixing ratio of these species include the emissions of DMS and SO 2 , transport of each species (through resolved-scale advection and su...
متن کاملThe Role of Corrosive Sulfur in Transformers and Transformer Oil
Corrosive sulfur and the effect that it has in transformer systems can be significant. The extent of the corrosion damage caused by sulfur, if left unchecked, can be so severe as to cause failure of the apparatus. The problems with corrosive sulfur have been recognized for quite some time. As early as 1948, F.M. Clark and E.L. Raab [1] issued a report on the subject for method development withi...
متن کاملIsotopic insights into microbial sulfur cycling in oil reservoirs
Microbial sulfate reduction in oil reservoirs (biosouring) is often associated with secondary oil production where seawater containing high sulfate concentrations (~28 mM) is injected into a reservoir to maintain pressure and displace oil. The sulfide generated from biosouring can cause corrosion of infrastructure, health exposure risks, and higher production costs. Isotope monitoring is a prom...
