Filtration and Separation In Sulfur Recovery

 · (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 ...

Hydrodesulfurization

Hydrodesulfurization (HDS) is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils. The purpose of removing the sulfur, and creating products such as ultra-low-sulfur diesel, is to reduce the sulfur dioxide (SO 2) emissions that result from using those fuels ...

Sulfur in plants and soil

Sulfur is required for the production of chlorophyll and a number of enzymes. It also helps legumes form associations with nitrogen fixing bacteria. Interestingly, the flavour and odour of mustard, onion and garlic is a result of sulfur containing compounds. The availability of sulfur to plants is influenced by a number of factors including:

Lowering the Soil pH with Sulfur. Mark Longstroth ...

Sulfur cannot be easily incorporated to the soil after plants are present. Surface-applied sulfur provides the same pH reduction as incorporated material, but takes longer. Check soil pH again before planting and apply additional sulfur if needed. Do not apply more than 400 lb. sulfur per acre at a time to established plantings.

The Sulfur Problem in the Metallurgical Industry

amounts of sulfur dioxide are generated. A fraction of this gas is captured and transformed into sulfuric acid and liquid S02 and the remainder is emitted to the atmosphere. Numerous proposals were made to solve this problem. Hydrometallurgy offers the only valid solution by which elemental sulfur instead of sulfur dioxide can be produced.
