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

Harbin Boiler Oil Manufacturer reminds you that density is the ratio of the quality of the oil to its specific volume. Common units include grams per cubic centimeter, kilograms per cubic meter, or tons per cubic meter. 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 for petroleum.
