Bitumen is manufactured from the distillation of crude oil during petroleum refining. It is produced to meet a variety of specifications based upon physical properties for specific end uses. Its main characteristics as an adhesive, as well as being waterproof, thermoplastic, durable, modifiable and recyclable make it ideal as a construction and engineering material. Most of the roads globally currently are paved with bitumen. Today the world’s demand for bitumen accounts for more than 100 million tons per year which is approximately 700 million barrels of bitumen consumed annually. Although bitumen can be found in natural form, the world currently relies for all purposes on petroleum with following different types.
There are five grades of bitumen consist of Penetration, Cutback, Emulsion, Performance and Viscosity grade.
Liquefied petroleum gas (LPG, LP gas, or condensate) is a fuel gas made of petrol which contains a flammable mixture of hydrocarbon gases, most commonly propane, butane, and propylene. However, the latter two typically compose 5% or less of the mixture.
– LPG is used as a fuel gas in heating appliances, cooking equipment, and vehicles. It is increasingly used as an aerosol propellant and a refrigerant replacing chlorofluorocarbons in an effort to reduce damage to the ozone layer. When specifically used as a vehicle fuel. It is often referred to as auto gas.
Base oils are used to manufacture products including lubricating greases, motor oil and metal processing fluids. Different products require different compositions and properties in the oil. One of the most important factors is the liquid’s viscosity at various temperatures. Whether or not a crude oil is suitable to be made into a base oil is determined by the concentration of base oil molecules as well as how easily these can be extracted.
– Base oil is produced by means of refining crude oil. This means that crude oil is heated in order that various distillates can be separated from one another. During the heating process, light and heavy hydrocarbons are separated – the light ones can be refined to make petrol and other fuels, while the heavier ones are suitable for bitumen and base oils.
