Question

18. Which engineering control is a chemical treatment commonly used to reduce overall sulphur levels
by separating the H2S from the gas stream and converting it to less toxic substances by combustion
and chemical reaction?

Answer 1

The Claus Process is the chemical treatment commonly used to reduce overall sulfur levels by separating the H₂S from the gas stream and converting it to less toxic substances by combustion and chemical reaction.

Claus Process-

• Claus process is the most common gas desulfurizing process.

• It is also used to recover elemental sulfur from hydrogen sulfide gas.
• The gasses over 25% of H₂S are suitable for sulfur recovery in the Claus plant.
• Hydrogen sulfide produced in the hydrogen desulfurization process is converted in the Claus plant to sulfur.
• Sulfur is used in the manufacturing of cosmetics, H₂SO₄, fertilizers, and medicines.

Therefore, the Claus process is a chemical treatment commonly used to reduce overall sulfur levels.
