Sour Gas (H₂S) Sweetening

Hydrogen sulfide (H₂S) is a colorless, flammable, corrosive and highly poisonous gas. It results from the decomposition of organic matter and smells like rotten eggs.

It is one of the most common impurities in natural gas; present in 15% to 25% of wells in the US and approximately 30% worldwide.

Humans can smell the rotten egg odor of hydrogen sulfide at a concentration of one part per million (ppm). Natural gas containing over 4 ppm is commonly referred to as “sour gas” and is considered too corrosive for pipelines to carry.

ANR’s patented natural gas sweetening process has proven effective in concentrations of as high as 3,000 ppm. Plus, unlike conventional chemical treatments it generates no environmentally hazardous by products.
