Honeywell's UOP has been selected by Japan's Taiyo Oil to
supply technology and catalysts to improve
operational flexibility and increase petrochemical production at the
Shikoku complex in Ehime, Japan.
The plant will install UOP's Tatoray process technology to allow it to boost
yields of certain petrochemicals by more than 70%, and
give the plant more flexibility to produce petrochemicals or gasoline as demand
Demand for petrochemicals in Asia is growing,
while gasoline demand is expected to decrease due to stricter
fuel specifications and increased demand for fuel-efficient
vehicles, said Pete Piotrowski, senior vice president and
general manager of UOP's process technology and equipment
The Tatoray process will significantly increase
mixed xylene and benzene production, allowing Taiyo to respond
to the regions growing petrochemical demand, and it will
give them the operational flexibility to also produce
high-quality gasoline as needed," he added. "We look forward to
continuing our longstanding relationship with Taiyo as we work
to complete this project.
UOP noted that it has worked with Taiyo for nearly 30
years, and has provided almost all of the process units for its
The new Tatoray unit is expected to produce 300,000
tpy of mixed xylene and high-purity beneze, which will require
no further processing. The unit is expected to start up in
The Tatoray process converts toluene and C9
aromatics to mixed xylenes and high-purity benzene without the
need for sulfolane extraction, according to UOP
officials. The process can more than double mixed xylene
production from a given naphtha feedstock, while significantly
reducing the overall cost of production, making it one of the
most economical ways to increase xylene and benzene yields in
an aromatics complex.
UOP says the latest-generation Tatoray
catalysts have also demonstrated superior activity and
stability in multiple commercial applications. These catalysts
enable higher on-stream efficiency with minimum cracking and
the lowest hydrogen consumption for petrochemical-grade benzene and
mixed xylene production.
As of 2013, UOP has licensed more than 95 aromatics
complexes, including 60 Tatoray units.
