Ethylene
Since receiving its first contract award in 1966
to build a 200,000 ton/year ethylene plant in Japan,
TOYO has maintained a technical alliance with Lummus
on ethylene process technology and has been involved
in 45 grassroots plants as well as
45 plant retrofit or revamping projects
that include technology licensing and/or EPC.
The largest ethylene plant ever designed by TOYO
has a capacity of 1,200,000 ton/year of ethylene,
licensed to Formosa Petrochemical Corp. of Taiwan in 2003.
The features of the Lummus ethylene process
are the use of an SRT furnace
(Short Residence Time furnace)
with an excellent selectivity, feedstock flexibility,
operational reliability and safety.
It is also easy to start up and uses energy efficient technology
incorporating a highly efficient steam cracker
and downstream fractionation units.
The recent innovation of Lummus's olefin technology
is listed below as new technology.
The new technology including the integration
of a steam cracker unit with OCT (Olefins Conversion Technology)
provided by Lummus, delivers improved plant performance
as presented below.
Business Description
The world's leading track record in ethylene plant construction
Since the execution of collaboration agreement with Lummus in 1962,
TOYO has constructed ethylene plants in 45 projects around the world.
Our work ranges from
basic design based on the license of Lummus to
detailed design, procurement, construction and commissioning.
Of the total 159 ethylene plants constructed since 1986 worldwide,
43% adopted the Lummus technology and
TOYO has constructed 17%. As can be seen,
the combination of Lummus and TOYO boast the leading shares
in licensed technologies and construction experience.

DETAILS
(TOYO, President and CEO Haruo Nagamatsu)
was awarded an expansion of naphtha cracking furnaces project
from Maruzen Petrochemical Co., Ltd.
to increase ethylene production at its Chiba Plant.
TOYO had participated in this project
from basic design stage
and highly appreciated by the client for optimum design
and proposals to emphasize shortest construction period.
Since 1967 when received an order of the third Ethylene Plant
at Chiba Plant, TOYO continued to execute various projects
of the client for many years.
Based on these experiences, TOYO will carry out this project
towards completion scheduled in 2020 under the safety-first policy.
TOYO’s domestic subsidiary, TEC Project Services Corporation (TPS),
will mainly take part in the construction work.
TOYO and TPS will cooperate to promote sales development
in domestic market and expand their business in Japan.
