Hydrogen Sulfide (H2S)

Definition - What does Hydrogen Sulfide (H2S) mean?

Hydrogen Sulfide is a flammable, poisonous and colorless gas with the chemical formula H2S. It is toxic at extremely low concentrations and is heavier than air. Hydrogen Sulfide smells like "rotten eggs" and can be harmful to several systems of the body, affecting mostly the nervous and the respiratory systems. It irritates the eyes, nose, throat, and lungs and also causes nausea and headaches. In extreme cases, it can affect the respiratory and the brain, leading to death.

Petropedia explains Hydrogen Sulfide (H2S)

Hydrogen sulfide to an extent, is one of the most vicious and deadly gases in the oil and gas industry. It is formed as a result of the decomposition of organic matter containing Sulfur during the drilling process. Exposure to high concentrations of this gas can lead to loss of consciousness. Due to its flammable properties, hydrogen sulfide can explode easily making oil and gas drilling sites extremely dangerous. It also affects the product value, the environment and damages infrastructure integrity. Managing hydrogen sulfide at every stage of hydrocarbon production, refining, and transportation can prove to be quite a challenging task.
