Description
Heavy fuel oils are mainly used as marine fuel, and HFO is the most widely used marine fuel at this time.
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. To achieve various specifications And quality levels, these residual fuels are blended with lighter fuels such as marine gasoil or marine diesel oil. The resulting blends are also referred to as intermediate fuel oils (IFO) or marine diesel oil. They are classified and named according to their viscosity. The most commonly used types are IFO 180 and IFO 380, with viscositiesof180mm²/s and 380mm²/s, respectively. If there is a predominance of heavy fuel oil in a blend, it is assigned to the heavy fuel oil category.
