The KPA (IV) Project located in Yeosu aimed at expanding Kumho P&B Chemicals’ plant in Yeosu National Industrial Complex. The end goal was to increase phenol production volume in response to the increased phenol demand in Korea and abroad. Through the plant extension, Kumho P&B Chemicals is able to produce 900,000 tons of cumene, 700,000 tons of phenol, and 435,000 tons of acetone annually. POSCO E&C completed the plant in 2016 on an EPC turn-key basis covering the design, procurement, and installation works.
