High sulfur content in fuel oil can cause metal equipment corrosion and environmental pollution. Depending on the sulfur content, fuel oil can be classified into high sulfur, medium sulfur, and low sulfur fuel oils. Besides carbon and hydrogen, sulfur is the third main component of crude oil, although its content is significantly lower than the first two, it is still a crucial indicator.

Harbin Boiler Oil Manufacturer reminds you that density is the ratio of the mass of the oil product to its specific volume. Common units include grams per cubic centimeter, kilograms per cubic meter, or tons per cubic meter, etc. Since volume changes with temperature, density cannot exist independently of temperature. For comparison convenience, the Western standard sets the density at 15°C as the standard density of petroleum.
