Bitumen
Azera Oil Is One Of Reliable Companies In That Supply All Types Of bitumen to asia, euro, africa
is a low-grade of crude oil which is composed of complex, heavy hydrocarbons. In an oil reservoir, bitumen is a thick, viscous fluid and must be extracted from the ground. When extracting it, a lot of heat and effort must be used to upgrade it to a better product. Although bitumen is hard to extract from the ground, it can bubble naturally to the surface of the Earth in petroleum seeps. These seeps are places where fossil fuels and petroleum products leak out of the Earth instead of being trapped deep below the ground. In these seeps, bitumen, asphalt, and tar bubble up into pools. Additionally, bitumen is the main fossil fuel component of oil sands. When bitumen combines with asphaltines a solid is formed that is useful for paving roads
Production
Once crude oil has been extracted from the ground, the production of bitumen can begin. The crude oil is pumped from the storage tanks and through a system that increases the temperature of the crude oil to 200°C. The oil then moves to a furnace, where it is heated even higher to approximately 300°C where it is vaporized partially into a distillation column. Here, the separation of the different components of the crude oil occurs. As lighter components rise to the top, heavy components—including the bitumen—fall to the bottom of the column. This process is known as fractional distillation. Finally, the bitumen is obtained by further distilling the residue in a vacuum distillation column. This type of bitumen is known as straight run bitumen. The grade of the bitumen depends on how much volatile material remains in the distilled bitumen—with more volatiles resulting in a less pure, more liquid product
