Safe and effective production infrastructure
The company, which forms the Maruzen Petrochemical complex together with five leading chemical companies, launched the production and supply of ethylene in 1961, as the ethylene center, the core of the petrochemical complex. The first ethylene plant (production equipment) was completed in 1964 and the third plant, the first in Japan with annual production of 300,000 tons, was completed in 1969. The fourth plant, boasting of highest annual production in Japan of 600,000 tons, was completed jointly with Mitsui Chemicals, Inc. and Sumitomo Chemical Co., Ltd. in 1994. The plant currently has the largest ethylene production capacity in Japan (690,000 tons).
In addition, the production volume of methyl ethyl ketone (MEK), the first petrochemical product based on domestic technology, has currently been expanded to 170,000 tons, one of the highest production capacities in the world, and, besides supplying domestic users, it is also being exported to countries around the world.
