Mazut:

Mazut is a heavy, low quality fuel oil, used in generating plants and similar applications. In the United States and Western Europe. It’s blended or broken down, with the end product being diesel.

Was used mainly for heating houses in the former USSR and mainly countries in Asia that do not have the facilities to blend or break it down into more conventional petro-chemicals.

Mazut-100 is a fuel oil that is manufactured to GOST specifications, a system used for Russan Standards.  Mazut is almost exclusively manufactured in the Russian Federation. This product is typically used for larger boilers in producing steam since the BTU content is high. The most important consideration when grading this fuel is the sulfhur content, which can mostly be affected by the source 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. Mazut is much like Number 6 Oil, and is part of the products left over after gasoline and lighter components are evaporated from the crude oil.

The main difference between the different types of Mazut-100 is the content of sulphur. The grades are represented by these sulfuric levels:

• ”Very Low Sulphur” is mazut with a sulphur content of 0.5%

• ”Low Sulphur” is a mazut with a sulphur content of 0.5-1.0%

• ”Normal Sulphur” is a mazut with a sulphur content of 1.0-2.0%

• ”High Sulphur” is a mazut with a sulphur content of 2.0-3.5%

Very Low Sulfur mazut is generally made from the lowest sulfur crude feedstocks. It has a very limited volume to be exported because of the strict quotas for export and is mainly used in the domestic market. Low to high sulfur mazut is available from Russia and other CIS countries (Kazakhstan, Azerbaijan, Turkmenistan). The technical specifications are represented in the same way, according to the Russian GOST standard 10585-99. The Russian origin mazut demands higher prices.
