It is almost exclusively manufactured in the Iran, Russian Federation, Kazakhstan, Azerbaijan, and Turkmenistan. This product is typically used for larger boilers in producing Steam since the BTU content is high. The most important consideration (not the only consideration) when grading this fuel is the Sulfur content. It can mostly be affected by the source of feedstock. For shipment purposes, this product is considered a “Dirty Oil” product, and because viscosity drastically affect whether it is able to be pumped, shipping has unique requirements.
The main difference between the different types of M–100 is the content of Sulphur.
The grades are represented by these sulfuric levels:
• ”Very Low Sulphur” is with a Sulphur content of 0.5%.
• ”Low Sulphur” it is with a Sulphur content of 0.5–1.0%.
• ”Normal Sulphur” it is with a Sulphur content of 1.0–2.0%.
• ”High Sulphur” It is with a Sulphur content of 2.0–3.5%.
Very Low Sulfur Mazut is generally made from the lowest sulfur crude feedstocks.
