Tokuyama Complex｜Manufacturing flow

Tokuyama Refinery (now Tokuyama Complex) started operations in 1957 (Showa 32) as Idemitsu's first Refinery. In addition, in 1964 (Showa 39), the Idemitsu Petrochemical Tokuyama Plant (currently Idemitsu Kosan Tokuyama Complex) was completed adjacent to Refinery, and it began supplying ethylene to Shunan Complex companies. At the end of March 2014, crude oil processing function was suspended in accordance with the Act on the Advancement of Energy Supply Structure, and now it functions as a logistics base for petroleum products to ensure a stable supply of crude oil as a production base for petrochemicals and a supply of raw materials to the Shunan Complex. Furthermore, technologies are developed with the aim of making a petrochemical complex with the highest level of competitiveness in Asia.
