Savustusprosessissa

Savustusprosessissa, also known as the Savutuss process, is a chemical process used to produce hydrogen sulfide (H2S) from sulfur-containing materials, such as sulfur, pyrite, or sulfuric acid. The process is named after its inventor, the Finnish engineer Carl Savutuss, who developed it in the late 19th century. The Savutuss process is a wet process, meaning that it involves the use of water as a solvent.

The process begins with the dissolution of the sulfur-containing material in water, forming a solution of sulfuric acid and hydrogen sulfide. The solution is then heated to a temperature of around 100 degrees Celsius, causing the hydrogen sulfide to evaporate. The remaining solution is then cooled and the sulfuric acid is crystallized out. The hydrogen sulfide gas is then collected and can be used for various industrial applications, such as in the production of sulfuric acid, fertilizers, or as a fuel in the petrochemical industry.

The Savutuss process is a relatively simple and inexpensive method for producing hydrogen sulfide, making it a popular choice for many industries. However, it does have some limitations, such as the need for a large amount of water and the potential for the formation of sulfur dioxide as a byproduct. Despite these limitations, the Savutuss process remains an important method for the production of hydrogen sulfide and continues to be used in many industrial applications today.
