Bitumen a black viscous mixture of hydrocarbons obtained naturally or as a residue from petroleum distillation. It is used for road surfacing and roofing. Bitumen is a mixture of Organic Liquids that are highly Viscous, Black, Sticky, Entirely Soluble in Carbon Disulfide, and composed primarily of highly condensed Polycyclic Aromatic Hydrocarbons. Naturally occurring or crude bitumen is a sticky, tar-like form of petroleum which is so thick and heavy that it must be heated or diluted before it will flow. At room temperature, it is much like cold molasses. Refined Bitumen is the residual (bottom) fraction obtained by fractional distillation of crude oil. It is the heaviest fraction and the one with the highest boiling point, boiling at 525 C (977 F).
Petroalliance are involved in import and the supply and trade of Bitumen Oil. This oil is a dark and viscous liquid which is sticky in texture. It is widely used in road construction, waterproofing, paints, enamels etc. It is available to clients in different types of settings at highly affordable prices. It is widely acclaimed amongst our client base for its supreme quality.
Uses of Bitumens
Bitumen is primarily used for construction and paving of roads. Its other uses are for Bituminous Waterproofing Products, including the use of bitumen in the production of roofing felt and for sealing flat roofs.
Modern mineral base oils are the result of a long and complex distillation and refining processes. The feedstock used is crude oil. This substance is not of uniform quality but consists of several thousands of hydrocarbon compounds in which the elements carbon and hydrogen are present in all molecules and, in part, are bound to other elements.
The hydrocarbons can be divided into three main groups: paraffinic, naphthenic and aromatic. Paraffinic hydrocarbons can be further divided into two subgroups: normal paraffinic and iso- paraffinic.
Paraffinic hydrocarbons are the best lubricants. The distillation process in the refinery separates the hydrocarbons contained in the crude into cuts based on the molecule size.
Furthermore, as many unwanted substances as possible are removed in the process, such as sulphur, aromatic hydrocarbons, paraffin wax, etc. In other words the mineral oil production process is physical cleaning and the end product is so-called paraffinic base oil.
Most of the hydrocarbons in the base oil are paraffinic, but it also contains naphthenic and aromatic molecules. When the finished lubricant, such as motor oil, is made of these, several additive compounds are used to improve the base oil properties.
The final outcome can also be so-called naphthenic base oil, where most of the hydrocarbons are naphthenic. Their cold properties are excellent.
