Sour Gas
Subject: Chemistry | Topics:

Sour gas is propane or any additional gas containing quite a lot of hydrogen sulfide (H2S). Natural gas is usually thought to be sour if there are more than 5. 7 milligrams associated with H2S per cubic meter of propane, which is equivalent to approximately 4 ppm by volume under normal temperature and strain. However, this tolerance varies by state, state, or possibly agency or application.
