What is the difference between heavy fuel oil and crude oil?
Heavy fuel oil is a residual fuel incurred during the distillation of crude oil. The quality of the residual fuel depends on the quality of the crude oil used in the refinery. As these are blends of heavy fuel oil and lighter fuels, they can also be referred to as a heavy marine diesel oil.
Is fuel oil the same as crude oil?
fuel oil, also called furnace oil, fuel consisting mainly of residues from crude-oil distillation. It is used primarily for steam boilers in power plants, aboard ships, and in industrial plants. Commercial fuel oils usually are blended with other petroleum fractions to produce the desired viscosity and flash point.
Is HFO crude oil?
Heavy fuel oil is a residual fuel incurred during the distillation of crude oil. It is used to generate motion and/or heat that have a particularly high viscosity and density.
Why can crude oil not be used straight out of the ground?
Crude oil is a highly variable mixture of heavy and light hydrocarbons that need to be separated in a refinery to turn them into usable products. For these different reasons it is impossible to develop a universal boiler or engine capable of running on all crude oils.
What is HFO fuel used for?
HFO is predominantly used as a fuel source for marine vessel propulsion due to its relatively low cost compared to cleaner fuel sources such as distillates.
Is diesel fuel and fuel oil the same?
Unlike the hydrocarbons in gasoline vs diesel, the hydrocarbons in diesel and fuel oil are very similar. In fact, they are almost the same in several cases. The hydrocarbon makes up of diesel fuels, “are approximately similar to fuel oils used for heating (fuel oils no. 1, no.
What HFO means?
The generic term heavy fuel oil (HFO) describes fuels used to generate motion and/or fuels to generate heat that have a particularly high viscosity and density. The resulting blends are also referred to as intermediate fuel oils (IFO) or marine diesel oil. …
Why do ships use HFO?
Since the middle of the 19th century, HFO has been used primarily by the shipping industry due to its low cost compared with all other fuel oils, being up to 30\% less expensive, as well as the historically lax regulatory requirements for emissions of nitrogen oxides (NOx) and sulfur dioxide (SO2) by the IMO.
