... by breathing it. The effects depend on how much hydrogen sulfide you breathe and for how long. Exposure to very high concentrations can quickly lead to death (see table1 ). The oil and gas industry and governmental agencies have set acceptable limits for working in areas with H2S exposure...

..., the Electrical Submersible Pumps (ESPs) have been deployed across different oil fields in an Arena of Artificial Fields. It was a proven fact that the typical run life of an ESP can exceed multiple years. However, that fact could be reversed especially in designated fields with high Hydrogen Sulfide (H2S...

... Abstract A chemical treating process is described that reduces dissolved hydrogen sulfide gas in crude oil to a concentration of less than 50 ppm. Such a process system is readily available for field installation with a minimum of surveillance being required. The treating takes place between...
