Ethylbenzene and Styrene
UOP offers a full range of state-of-the-art ethylbenzene and styrene
monomer processes. Styrene monomer (SM) is an important petrochemical
used in the production of polystyrene and other styrenic resins such
as acrylonitrile butadiene styrene (ABS) and styrene acrylonitrile
(SAN). Ethylbenzene (EB) is produced primarily by alkylation of benzene
with ethylene. EB is then converted to SM by dehydrogenation.
The EBOne process is a liquid-phase alkylation process that employs a proprietary
zeolite catalyst system developed and manufactured by UOP. The EBOne process
provides exceptional product quality at over 99.6 wt% yield. The catalysts used
in the EBOne process can be regenerated repeatedly, thereby avoiding the significant
catalyst disposal problems associated with older aluminum chloride catalyst systems.
Compared to other EB synthesis technologies, the EBOne process offers better
product quality, better heat integration, a lower investment cost, and a far
more rugged and reliable catalyst system.
The Lummus/UOP Classic SM process is a deep-vacuum, adiabatic EB dehydrogenation
technology, well known for its efficient heat integration and exceptional mechanical
integrity. The unique dehydrogenation reactor system is designed to operate at
a very cost-effective, minimal operating pressure to achieve the highest SM selectivities
at high conversions. The Lummus/UOP Classic SM process uses state-of-the-art
dehydrogenation catalysts developed and manufactured by Sud-Chemie A.G.
The Lummus/UOP Smart SM process offers an attractive way to increase the capacity
of existing SM units through the use of an innovative oxidative reheat technology.
The capacity of existing SM units can be increased up to 30% with minimal investment
in new equipment.
