Bitumen production process

Petroleum bitumens are produced in two ways: Straight Run and Air Blowing. The aeration method is used when the bitumen (feed) does not meet the expected properties. In this case, blowing air into the feed (feed) produces a product with modified properties at temperatures between -10º-190ºC. This process is sometimes referred to as Asphalt Oxidation and its product is Oxidized Asphalt, but the terms Air Blowing and Air Blowing Asphalt are more appropriate because of the process of dehydration and polymerization. And oxygen will not enter the aeration product except in very small amounts. In the aeration industry there are two ways of continuous (Batch Process) and continuous (Batch Process).

Bitumen chemistry

Bitumen; A dark brown-black hydrocarbon compound in solid, semipermeable or viscose form, with a natural or refined origin, containing mainly high molecular weight hydrocarbons. It is completely soluble in carbon disulfide (CS2), trichloroethylene (C2HCl3) and xylene (C6H4 (CH3) 2). Its vapor pressure is negligible at ambient temperature and is almost odorless. The most common and widely used bitumen is petroleum bitumen which is physically a homogeneous material and chemically a heterogeneous mixture of different chemical compositions. This hydrocarbon mixture generally comprises 90% carbon and hydrogen atoms and the rest, nitrogen, sulfur and oxygen, and small amounts of nickel, iron, magnesium, and so on. It has an elastic, not a viscous material, but the bitumen behavior involves a combination of the two viscoelastic



Applications of bitumen

Bitumen is usually used in both construction and insulation areas. Approximately 2% of bitumen is used in road construction, and insulation accounts for only 2% of bitumen consumption, including floor coverings, roofing, underground pipes, metal shielding as well as sealing of tanks, canals, Bridges and fixing of smooth sand, coloring and …

Bitumen Types

Bitumen: A set of bitumens that are naturally produced by the effects of weather and time and are used without the need for distillation methods and are very diverse in composition and properties.
Bitumen Bitumen: Black and hard materials that are remnants of coal tar distillation. Freshly fractured surface is glossy, melts with rapid drop in viscosity during heating and their melting temperature depends on the production method.
Petroleum bitumen: These are those bitumen whose origin is crude oil. These bitumens are solid and semi-solid bitumens that are obtained directly from the distillation of crude oil or by other additional operations such as blowing air and have higher uses and consumption than other types of bitumen.


Blown Bitumen

Blown bitumen are produced in a vacuum reaction (VB) and air reaction process in bitumen reactors and are produced in different grades depending on the process conditions.


Special bitumen

These types of bitumen are manufactured according to customer requirements with specific specifications for regional and occasional applications and are mainly in the form of modified bitumen and oxidized bitumen.


Emulsion bitumen

It is produced by mixing bitumen and aqueous phase for various purposes such as single coat, prime coat, cold asphalt and asphalt restoration, which is divided into three categories: cationic, anionic and neutral depending on the type of stone material. The two-phase mixing speed is classified into four groups: accelerator, accelerator, decelerator, and decelerator. This product complies with environmental requirements and is a good substitute for bitumen


Barrels and overlays

The barrel factory is equipped with production line and automatic color line in accordance with current standards. The 6,000-barrel-a-day plant can produce metal barrels in three different types.

Bitumen packaging in polymer bags has provided the possibility of delivering one tonne of bitumen at a capacity of 30 tons per hour.
The company has 3 full-barrel arms with a capacity of 1,000 tons per day to deliver bitumen to the metal barrel.

What Is Bitumen(Asphalt)?

Bitumen is a black or dark-colored (solid, semi-solid, viscous), amorphous, cementitious material that can be found in different forms, such us rock asphalt, natural bitumen, tar and bitumen derived from oil, which is referred to as petroleum bitumen.Currently most of the roads globally 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.Petroleum bitumen is typically referred to as bitumen or asphalt. In Europe for instance bitumen means the liquid binder. In North America, on the other hand the liquid binder is referred to as asphalt, or asphalt cement.OriginIn general the term “bituminous materials” is used to denote substances in which bitumen is present or from which it can be derived. Bituminous substances comprise of primarily bitumens and tars.Bitumen occurs in nature in several forms: hard one – easily crumbled bitumen in rock asphalt and softer, more viscous material which is present in tar sands and asphalt ‘lakes’. Another way in which bitumen can be obtained is through petroleum processing in this manner the bitumen is essentially the residue yielded through a distillation process of petroleum. Although bitumen can be found in natural form, the world currently relies for all purposes on petroleum. The material has been produced in this way for over a hundred years.Tars on the other hand do occur in nature. Tars derive as condensates from the processing of coal (at very high temperatures), petroleum, oil-shale, wood or other organic materials. Pitch is produced when a tar is partially distilled so that the volatile components have evaporated.Often coal tar is confused with bitumen however they are two entirely chemically different products and should not be mistaken. For the distinction drawn between petroleum bitumen and coal tar see the distinction table below:
