Bitumen is an oil derivative that is usually used in the field of road construction and insulation and is usually available in both barrel and bulk form in the market. It is a black material with high viscosity in the form that it is solid at ambient temperature and its viscosity decreases with increasing temperature. The price of bitumen goes through many political events every year and under the influence of these events experiences an increase or decrease. Request First rate bitumen from this site.

What bitumen looks like?

What bitumen looks like? Bitumen is a black, pasty material used in moisture insulation and asphalt construction. There are different types of bitumen, each of which has a specific application. Bitumen is a derivative of oil and is often produced in oil refineries.

Bitumen is a black to dark brown hydrocarbon that dissolves completely in carbon sulfide and carbon tetrachloride. Bitumen is solid at ambient temperature. But as the temperature rises, it becomes a paste and then liquefies.

The important use of bitumen is due to the existence of two important properties of this material;

  •  Waterproof
  •  Adhesion

Bitumen is usually obtained by distilling crude oil. Such bitumen is called petroleum bitumen or distilled bitumen. Petroleum bitumen is the product of two stages of crude oil distillation in the distillation tower. In the first stage of distillation, light materials such as gasoline and propane are separated from crude oil. This process takes place at a pressure close to one atmosphere (units). In the second stage, heavy compounds such as diesel and kerosene are extracted. This process takes place at a pressure close to vacuum. 

However, some types of bitumen are obtained in nature due to the gradual conversion of crude oil and the evaporation of its volatiles over many years. Such bitumen is called natural bitumen and it is more durable than oil bitumen.

Manifacturing process of bitumen in company After separating oily or fuel materials in vacuum conditions in the bitumen production process, the vacuum tower residue first enters the lubrication unit, then enters the Visbraker unit to produce furnace oil or fuel oil, and finally enters the asphalt or bitumen unit.

In the bitumen unit of aeration operation and oxidation inside the reactor by Conventional and Biturox methods, based on temperature changes and aeration rate, the feed is converted into different grades of bitumen.

  Interrupted process:

First, the tower is filled with the desired surface of bitumen. Preheating is achieved by rotating the bitumen between the furnace and the tower. Direct heating using a fire tube in the tower reduces the quality of the product. When the temperature of the bitumen reaches 190 to 240 degrees Celsius, complete aeration begins, then the heat of the reaction raises the temperature of the bitumen to 240 to 260 degrees Celsius and the temperature is maintained there.

Blowing time varies between 3 to 24 hours. Just as water is not sprayed into the container at the beginning of the operation to prevent foaming, water injection into the container should not be used during cooling when the temperature drops below 200-210 ° C. bitumen uses are very common today.
