Corrosion behavior of api 5l x70 carbon steels in hydrogen sulfide environments
(2021-01-01)
As we all know, corrosion of pipelines by hydrogen sulfide is the most worrying factor in the production and transport of oil and gas. In this work the corrosion behavior of API 5L X70MS and X70MO low carbon steels in ...
A THERMODINAMIC CORROSION STUDY OF CARBON STEELS IN HYDROGEN SULFIDE - EXPLORING CHEMICAL EQUILIBRIUM CONCEPTS
(Soc Brasileira Quimica, 2018-05-01)
This study addresses an inherent problem to the oil and natural gas exploration and production industry, the corrosion of pipes and tanks by H2S. H2S with water emulsified in the oil or H2S with the water vapor mixed in ...

Hemeproteins as targets for sulfide species
(Mary Ann Liebert, 2020-01-02)
The binding of sulfide to ferric hemeproteins has been described in more than 40 systems, including native proteins, mutants, and model systems. Mechanisms of sulfide binding to ferric hemeproteins have been examined by a ...
A comparative study on the anti-inflammatory effects of single oral doses of naproxen and its hydrogen sulfide (H2S)-releasing derivative ATB-346 in rats with carrageenan-induced synovitis
(Medical Gas Research 2013, 3:24London, 2013)
Abstract
Background
Non-steroidal antiinflammatory drugs (NSAIDs) are the most commonly prescribed agents for arthritic patients, although gastric effects limit their long-term use. Considering ...
Minibioreactor-gas collector for determining bacteria-produced hydrogen sulfide
(Pontificia Universidad Católica de Valparaíso, 2003)
Experimental (electrochemistry) and theoretical (ab initio and density functional theory) studies of hydrogen and sulfide adsorption on palladium (100) surface.
(Soc Brasileira QuimicaSao PauloBrasil, 2001)
Experimental (electrochemistry) and theoretical (ab initio and density functional theory) studies of hydrogen and sulfide adsorption on palladium (100) surface.
(Soc Brasileira Quimica, 2001-07-01)
The adsorption of H And S2- species on Pd (100) has been studied with ab initio, density-functional calculations and electrochemical methods. A cluster of five Pd atoms with a frozen geometry described the surface. The ...
Active potassium niobates and titanoniobates as catalysts for organic sulfide remediation
(Elsevier Science, 2016-02)
Pure (KNbO3) and titanium-substituted (KTi0.1Nb0.9O3 and KTi0.2Nb0.8O3) potassium niobates with perovskite crystalline structures were prepared, characterized and tested as catalysts in the selective oxidation of ...
