Determination Of H2s And Total Sulfur In Natural Gas

Hydrogen Sulfide (H2S) is a chemical compound comprised of one Sulfur Atom and two Hydrogen Atoms. It is a colorless, extremely poisonous gas that reeks of rotten eggs. Hydrogen Sulfide is highly corrosive and renders some steels brittle, leading to sulfide stress cracking. Hydrogen Sulfide is formed when bacteria breaks down organic matter in the absence of oxygen and therefore is often found in crude oil and natural gas deposits. Due to the toxic and corrosive properties of Hydrogen Sulfide and its natural presence in natural gas, it is imperative to measure and control of the concentration levels of this compound within natural gas pipelines. This paper will address the properties, purpose of measurement and measurement methods for H2S and discuss how these methods can be adapted to the measurement of Total Sulfurs as well as H2S in natural gas streams
