Exporter of Bitumen
60/70 and 80/100
Bitumen is an oil based substance. It is a semi-solid
hydrocarbon product produced by removing the lighter fractions
(such as liquid petroleum gas, petrol and diesel) from heavy
crude oil during the refining process. As such, it is correctly
known as refined bitumen. In North America, bitumen is
commonly known as “asphalt cement” or “asphalt”. While
elsewhere, “asphalt” is the term used for a mixture of small
stones, sand, filler and bitumen, which is used as a road paving
material. The asphalt mixture contains approximately 5% bitumen.
At ambient temperatures bitumen is a stable, semi-solid
substance.

The vast majority of refined bitumen is used in construction:
primarily as a constituent of products used in paving and
roofing applications. According to the requirements of the end
use bitumen is produced to specification. This is achieved
either by refining process or blending.
It is estimated that the current world use of bitumen is
approximately 102 million tonnes per year. Approximately 85% of
all the bitumen produced is used as the binder in asphalt for
roads. It is also used in other paved areas such as airport
runways, car parks and footways.
Typically, the production of asphalt involves mixing sand,
gravel and crushed rock with bitumen, which acts as the binding
agent. Other materials, such as polymers, may be added to the
bitumen to alter its properties according to the application for
which the asphalt is ultimately intended.
A further 10% of global bitumen production is used in roofing
applications, where its waterproofing qualities are invaluable.
The remaining 5% of bitumen is used mainly for sealing and
insulating purposes in a variety of building materials, such as
pipe coatings, carpet tile backing and paint.
Petroleum bitumen
60/70 & 80/100
Petroleum bitumen is often confused with tar. Although bitumen
and coal tar are similarly black and sticky, they are distinctly
different substances in origin, chemical composition and in
their properties. Coal tar is produced by heating coal to
extremely high temperatures and is a by-product of gas and coke
production. It was widely used as the binding agent in road
asphalt in the early part of the last century, but has since
been replaced by refined bitumen.
Bitumen is also sometimes confused with petroleum pitch which,
although also derived from crude oil, is a substance produced by
a different process from that used for refined bitumen.
Petroleum pitches are the residues from the extreme heat
treatment or “cracking” of petroleum fractions. Their properties
and chemical composition are therefore quite different from
those of
bitumen.
Naturally-occurring bitumen, sometimes also called natural
asphalt, rock asphalt, lake asphalt or oil sand, has been used
as an adhesive, sealant and waterproofing agent for over 8,000
years. But it occurs only in small quantities and its properties
are quite different from refined bitumen.

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 bitumen. The
pressure and temperature conditions within the
vacuum process will determine the hardness of
the short residue, and as such the grade
of 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.
