Ensuring Efficient Pollution Control

Sour gas and sour water are terms used to describe gas and water containing significant amounts of hydrogen sulfide. Sour water and sour gas applications abound at oil refineries and natural gas plants; the “sweetening” of gas and water refers to the processes used to remove hydrogen sulfide and organosulfide compounds. Hydrodesulfurization is a method of sulfur removal employed at refineries and natural gas plants.
