Definition - What does Hydrogen Sulphide mean?
Hydrogen Sulphide, also known as Sour Gas is a flammable and colorless gas which is toxic at extremely low concentrations. It is heavier than air. Hydrogen Sulphide 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; it also causes nausea and headaches. In extreme cases, it can affect the respiratory center located in the brain, leading to death.
Petropedia explains Hydrogen Sulphide
Hydrogen Sulphide to an extent, is one of the most vicious and deadly hazards in the oil and gas industry. It is formed as a result of the decomposition of organic matter containing Sulphur during the drilling process. Exposure to high concentrations of this gas can lead to loss of consciousness. Due to its flammable properties, Hydrogen Sulphide 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 Sulphide at every stage of hydrocarbon production, refining, and transportation can prove to be quite a challenging task.
