The mixture of two raw materials, vacuum baton (VB) and vacuum slab (VS), is aerated in bitumen production reactors under special pressure and temperature between 200 and 300 degrees Celsius to combine the hydrogen atoms in the bitumen molecules with oxygen in the air and create reactions. Polymerization of heavier hydrocarbons is obtained which has a lower degree of penetration and a softer point than the original pure bitumen. This type of bitumen has a softness of 85 and a permeability of 25. For more information about Latest bitumen prices in 2020, visit our website.
How bitumen is obtained?
Batch Process In a discontinuous process, an aeration tower with a certain volume of feed is filled and a pre-heater air blower or compressor (Blower or Compressor) aeration tower (Oxidizer Tower) system for collecting and burning vapors. 2- Continues Process In continuous process, feed with a definite and controllable flow rate and temperature of reducing equipment costs and maintenance, increasing efficiency and amount of production per unit time, reducing the thermal load of feed preheaters, ease of control operation and process due to The continuous nature of the process is the reduction of air consumption and shortening of aeration time.

Bitumen production units Bitumen feed is the vacuum bottom distillation tower which is produced in the distillation unit and flows to the aeration tower and the air required for oxidation is supplied by the blower and compressor and its shortage is provided through the utility unit.
After aeration, the bitumen product is taken out of the tower with a temperature of about 250 ° C to 265 ° C and is cooled by three heat exchangers and directed to the product storage tanks. The temperature of these tanks is maintained at 180 ° C, which is sampled with the filling of each tank and sent to the loading tanks after confirmation of the quality control of the laboratory. To prevent environmental pollution, light gases emitted from the top of the reaction tower caused by dehydrogenation after entering the knock out drum and settling of heavy liquids are directed to the incinerator furnace and burned with natural gas at a temperature of 800 ° C. It becomes. At present, only 60/70 bitumen is produced in this unit.
The production capacity of unit one (old) according to the design of the country of manufacture (USA) was BPD5400 barrels per day, which has now been increased to 22,000 BPD per day. In the asphalt section, two or two reactors of Porner bitumen (R-1601 A, B) have been designed separately to make different types of bitumen, each with a capacity of 5800 BPD per day, which has now been increased to a total of 18000 BPD per day. .
This unit is designed for making different types of bitumen, the difference with the asphalt unit is that the tower has two shells and has a stirrer. In this unit, feed is provided from the bottom of the vacuum tower of distillation units and a heavy crude oil path has been added to the system to make bitumen of 85.25. Two air compressors with a capacity of M3 / H5000 supply air to this unit.
The remarkable system in this unit is the control of the liquid level in the towers using the speed of the motors to save electricity consumption. The cold bitumen section of roads is designed to make cold bitumen with the letters MC-250 and RC-70 with a capacity of 7100 B / D per day. The main feed is 60.70 bitumen which is mixed with kerosene and naphtha in certain proportions, respectively. It is then cooled in heat exchangers and directed to bitumen storage tanks. After testing each tank and confirming the quality control laboratory, the product is ready for loading. For more information about bitumen price per ton, visit our collection website.
