In-depth study on the solubility of elemental sulfur in sour gas mixtures based on the Chrastil's association model

Petroleum, 2016
Accurately predicting the solubility of elemental sulfur in sour gas mixtures is a primary task. As a current and widely-used model on the solubility of elemental sulfur in sour gas mixtures, Chrastil's association model has a big error in the process of

Acquisition of elemental sulfur by sulfur‐oxidising Sulfolobales

Environmental Microbiology
Abstract Elemental sulfur (S 8 0 )‐oxidising Sulfolobales (Archaea) dominate high‐temperature acidic hot springs (>80°C, pH <4). However, genomic analyses of S 8 0 ‐oxidising members of the

Iron and sulfur utilisation patterns in chemolithotrophic cultures [PDF]

, 2012
In this study, the growth and behaviour of chemolithotrophic organisms in the presence of both ferrous and tetrathionate ions was investigated. Given the impact of chemolithotrophic metabolic activity upon the chemistry and leaching of mineral sulfide ...

Characterization of lacustrine iron sulfide particles with proton-induced X-ray emission. [PDF]

, 1992
Black particles, collected by filtration (1.2~pm pore size) from the anoxic waters of a soft-water lake, were examined by a scanning proton microprobe which permitted quantitative elemental analysis by proton-induced X-ray emission (PIXE) and Rutherford ...

Sulfur, fresh cassava root and urea independently enhanced gas production, ruminal characteristics and in vitro degradability

BMC Veterinary Research, 2021
Background Total fresh cassava root (FCR) production was 275 million tonnes in 2018 which equals 61.1 % of the total production, and Thailand produced 10.7 % FCR of the total production. FCR is one of the main energy source for ruminant.

Recovery of Sulfur from the Residues of the Chemical Method for the Purification of Sulfur from the Farsch Mine in the Al-Mishraq Mine

Iraqi Journal of Industrial Research, 2023
This research aims to recover sulfur from sulfur residues of the chemical method for purifying mine sulfur in the Al-Mishraq mine by studying and using thermal and air-thermal treatment with a temperature range of 130-190 oC and an increase of 10 ...

Elemental sulfur aerosol-forming mechanism [PDF]

Proceedings of the National Academy of Sciences, 2017
SignificanceThe elemental sulfur aerosols are an important constituent in the atmospheres of Earth, Mars, and Venus. There is now evidence suggesting that these aerosols have also played a role in the evolution of early life on Earth. Traditionally, the photolysis of sulfur gases by UV light is thought to be the main mechanism for the formation of ...

Persistence of elemental sulfur spray residue on grapes during ripening and vinification [PDF]

, 2015
Elemental sulfur is an effective and economic method to control powdery mildew on grapes, but too much sulfur residues can impact fermentation. This paper discusses a novel way to measure sulfur in the field and winery to help grape growers determine ...
