EghtesadOnline: Director of National Iranian Oil Company (NIOC) for International Affairs Mohsen Qamsari said that Iran exports 1.500 million tons of mazut monthly.
According to ISNA, the country set a record in export of the material in the third month of Iranian calendar year (May 21- June 20), the Iranian oil official said.
The material is mainly exported to Asia, China and Singapore, Qamsari said.
Iran is now exporting 10 million tons of mazut monthly, he said.
Mazut is a heavy, low quality fuel oil, used in generating plants and similar applications. In the United States and Western Europe, mazut is blended or broken down, with the end product being diesel.
Mazut may be used for heating houses in the former USSR and in countries of the Far East that do not have the facilities to blend or break it down into more conventional petro-chemicals.
In the West, furnaces that burn mazut are commonly called "waste oil" heaters or "waste oil" furnaces.
Mazut-100 is a fuel oil that is manufactured to GOST specifications, for example GOST 10585-75 (not active), GOST 10585-99 Oil fuel Mazut Specifications (active, last modified 07.01.2010) . (GOST is the Russian system of standards, much like ASTM, or ANSI, for example). Mazut is almost exclusively manufactured in the Russian Federation, Kazakhstan, Azerbaijan, and Turkmenistan. This product is typically used for larger boilers in producing steam since the BTU content is high.
