Benzene is normally recovered from aromatic hydrocarbon streams that also
contain toluene and mixed xylenes. Benzene is one of the largest-volume petrochemicals
and is the largest of the aromatics.
Benzene demand throughout the world is dominated by the production of three
derivatives: ethylbenzene, cumene and cyclohexane. These derivatives accounted
for more than 85% of benzene consumed globally in 2006.
The following pie chart shows world consumption of benzene:
North American benzene consumption will increase slightly between 2006 and
2011. The fastest-growing derivatives will be cumene and nitrobenzene.
Central and South America will see increases in all derivative manufacturing
through 2011. Ethylbenzene and nitrobenzene will exhibit rapid growth through
the forecast period.
Benzene demand in Western Europe is forecast to slightly decrease between
2006 and 2011. Despite declines, growth for cumene, cyclohexane and nitrobenzene
will experience moderate average annual growth rates.
Japanese benzene demand is forecast to increase slightly between 2006 and
2011. The rest of Asia will continue strong growth through 2011.
The largest anticipated demand for benzene will come from the Middle East,
with a rapid average annual growth rate between 2006 and 2011. Strong demand
for detergent alkylates and styrene in the global market will spur fast growth
for alkylbenzenes and ethylbenzene in the region.
