How is Bitumen manufactuered


The crude oil is pumped from storage tanks, where it is kept at about 60°C, through a heat exchanger system where its temperature is increased to typically 200°C by exchanging heat gained from the cooling of newly produced products in the refining process. The crude is then further heated in a furnace to typically 300° C where it is partly vaporized into an Atmospheric Distillation Column. Here the physical separation of the components occurs. The lighter components rise to the top and the heaviest components (the atmospheric residue) fall to the bottom of the column and pass through a second heat exchanger prior to treatment in a vacuum distillation column. Finally, Bitumen is obtained by vacuum distillation or vacuum flashing of atmospheric residue from the vacuum distillation column. This is "straight run bitumen”. This process is called bitumen production by straight run vacuum distillation.

An alternative method of bitumen production is by precipitation from residual fractions by propane or butane-solvent deasphalting. The bitumen thus obtained has properties which derive from the type of crude oil processed and from the mode of operation in the vacuum unit or in the solvent deasphalting unit. The grade of the bitumen depends on the amount of volatile material that remains in the product: the smaller the amount of volatiles, the harder the residual bitumen.

Specialists in bitumen view bitumen as an advanced and complex construction material, not as a mere by-product of the oil refining products.


IndianOil markets Bitumen from its Refineries located at Koyali(Gujarat), Mathura(UP), Panipat(Haryana), Barauni(Bihar), Haldia(WB) and CPCL(Tamil Nadu). Bitumen is available from these locations both in bulk as well as in packed drums. In addition to the refinery locations, packed bitumen is also marketed from upcountry locations Bokaro (Jharkhand), Guwahati (Assam), Haldwani (UP), Balasore (Orissa), Coimbatore and Madurai (Tamil Nadu)


CRMB is available from the refinery locations at Koyali, Mathura, Panipat, Haldia and Chennai.Packed CRMB is available at Haldia.


Emulsion is available from Haldia and Chennai refineries.
