Filtration and Separation In Sulfur Recovery - Chemical ...
Apr 01, 2013 (Page 1) Sulfur is a major contaminant in the oil and gas industry that exists in various forms and requires separation from both water and process streams. In the many plants that make up the sulfur recovery trail, filtration and other separation processes are important in minimizing process upsets caused by the presence of contaminants. In fact, contamination control through separation is a ...

What is Sulfur. Sulfur (S) is a bright, lemon yellow, soft, non-metallic element that has a very low thermal conductivity, meaning it cannot transfer heat very well. The touch of a hand will cause a sulfur crystal to crack because the crystal’s surface warms faster than the interior. Sulfur melts at 108 degrees Celsius.
