Iranian Bitumen

5/5 - (2 votes)

The Air Blowing Iranian Bitumen is produced by processing vacuum Bottom (VB) with air in a reactor tower continuously or as batch. And due to the control of the process conditions, different grades could be produced. The regular distillation process is discontinued at some point while the topped crude is still liquid. The heavy fraction is into a converter and air is blown through it while it is maintained at a high temperature. This process is continued until the Iranian Bitumen has attained desired properties. Often, such Iranian Bitumen is called Blown Iranian Bitumen . However, this is not strictly a true term because not only oxidation but also vaporization, Dehydrogenation, condensation, polymerization and other reactions occur during the air blowing process.
