What are the impacts of a low sulfur content in raw coal on the material selection for equipment in the pulping system?
If the sulfur content is relatively low and within the specified limits for sulfide control, low-alloy steel can be used for the equipment. Low-alloy steel possesses better comprehensive mechanical properties than carbon steel; as a result, the overall weight of the equipment might decrease. However, low-alloy steel is more expensive, and it is more susceptible to stress corrosion cracking than carbon steel. It’s safer to choose carbon steel!
