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. A key differentiator of heavy fuel oils is their sulfur content.
Light Cycle Oil (LCO) is the diesel boiling range material, which is produced in addition to gas and petrol in the Fluid Catalytic Cracking Unit (FCCU). LCO is treated in the diesel hydrotreater (DHT) unit to produce low sulphur
Naphtha is produced primarily from the distillation of crude oil and is the intermediate product between the light gases and the heavier kerosene. It can also be a component of natural gas condensates.
As refineries worldwide seek to operate more efficiently and extract more gasoline and other high value fuels from each barrel of crude oil, a solid carbon material known as petcoke is produced.
LLP, Kerosene, or lamp oil is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households.
