Bitumen is a solid, semi-solid or viscous hydrocarbon with a colloidal structure which is brown to black in colour. It is obtained by vacuum distillation of oil residues from atmospheric distillation of crude oil. Bitumen is often referred to as asphalt and is primarily used for surfacing of roads and for roofing material. This category includes fluidised and cut back bitumen.
Naphtha is a feedstock destined either for the petrochemical industry (e.g. ethylene manufacture or aromatics production) or for gasoline production by reforming or isomerisation within the refinery. Naphtha comprises material that distils between 30°C and 210°C.
Kerosene (other than kerosene used for aircraft transport which is included with aviation fuels) comprises refined petroleum distillate intermediate in volatility between gasoline and gas/diesel oil. It is a medium oil distilling between 150°C and 300°C
A light fuel oil obtained by distilling petroleum, used esp. in jet engines and domestic heaters and lamps and as a cleaning solvent and the main type of fuel used by jet-propelled airlines. It is clear in colour and used for its enhanced performance at the colder temperatures to which airlines are exposed. Its use in international transportation has meant it is usually exempt from taxation unlike standard fuels.
Base oil is refined out of petroleum crude oil to which additives and other substances are added to produce a lubricant (a typical lubricant contains at least 90% base oil and less than 10% additives). A lubricant is by definition a substance used in various industries and equipments (automotive sector being the prime consumer) to reduce wear and lower friction between moving parts. Each crude oil, which base oils are derived from, has specific properties which are passed onto its refined products. These include viscosity, sulphur, color, density, flash point, pour point and volatility which define the quality of the products made from the crude oil. How the crude petroleum is refined will also influence the charateristics of the base oils.
Also we can provide Base Oil Group II & Group III in FOB or CFR delivery term.
