Hydrogen sulfide gas is found in crude oil supplies worldwide. Because this compound is harmful to the refinery's equipment, the environment, and the consumer, it is removed in several refinery processes, particularly hydrodesulfurization and sweetening. Sulfur plants remove the hydrogen sulfide byproducts from these processes and turn it into useful elemental sulfur.

About 80 million tons of sulfur are produced annually. The majority is from refinery sulfur recovery units. Many everyday applications use this sulfur including medicine, cosmetics, fertilizers, rubber products, and pesticides.

The Sulfur Acid Plant training course:

• Discusses the process most commonly used for sulfur recovery
• Explains the system components used in the process
• Discusses the uses of elemental sulfur
• Explores the regulatory issues surrounding sulfur production

Sulfuric Acid Plant is part of the Refinery Operations training series.
