Iran bitumen manufacturing process
Iran Bitumen is produced from selected crude oils through a process of fractional distillation. The crude oil is heated to temperatures of between 300 and 350 degrees Celsius and fed into a distillation column allowing the lightest fractions of the crude to separate, through vaporization, from the heavier fractions, which remain liquid. The higher boiling point fractions are then drawn – off via a heat exchanger and enter a vacuum distillation column. This process produces a short residue that is used to manufacture several grades of Iran bitumen.The pressure and temperature conditions within the vacuum process will determine the hardness of the short residue, and as such the grade of Iran bitumen produced. The short residue may be further modified by air blowing in which air is passed through the residue at temperatures of 250 – 300 degrees Celsius.
