Bitumen

Process by which compressed air is blown into vacuum bottom residue, typically at 230–260 °C in a reactor. This process result in complex reactions (such as Dehydrogenation، Polymerization، Oxidation). Different grades for suited applications produced Due to ratio of air blowing.

Application:

Road: 90 percent of the bitumen is used in the construction and maintenance of roads.

Roofing: 10 percent of the bitumen is used in the roofing and other. (Canals and tunnels, pipe coating)

Types:

Natural Bitumen: This bitumen is extracted from mines, which are used in many industries, including road construction, the paint industry, polish and insulation of tanks and tubes and molding.

Coal Tar: Coal tar is a black or dark-brown a residue produced by the heat treatment of coal. It is a solid at room temperature.

Petroleum Bitumen: Mixture of hydrocarbons derived from petroleum. Black or brown, it varies from viscous to solid, producing by air blowing process vacuum bottom. (Crude oil derivatives)
