With Heavy Oil Upgrading(HOU) facilities designed to crack 155,000 barrels of bunker C oil a day to produce high-valued products such as gasoline, kerosene, and diesel, as well as advanced facilities such as those designed to desulfurize 272,000 barrels of kerosene and diesel a day, GS Caltex proactively responds to the rapidly changing market environment.
GS Caltex vigorously advanced into the petrochemical industry, as the company established plants within its Yeosu Plant Complex to produce polypropylene in 1988, and paraxylene and aromatics in 1990, respectively.
GS Caltex began its aromatics business vigorously with the construction of a plant to produce 200,000 tons of paraxylene and 300,000 tons of aromatics a year in September 1990. Investments in the business have continued in order to keep up with rapidly changing market situations. In April 2003, the Company completed the construction of its third paraxylene unit with a production capacity of 350,000 tons by employing MTPX technology, an advanced technology developed by Exxon-Mobil. The Company's total aromatics production capacity is 2,800,000 tons including 1,200,000 tons of paraxylene, 900,000 tons of benzene annually. This is the world's largest aromatics plant as single site.
Also, polypropylene business, the other part of petrochemical group, was launched in 1988, with the introduction of the Dow Chemical Company's Unipol process of fluidized bed-based vapor-phase polymerization, which allowed the production and supply of the finest-quality polypropylene. We are now capable of producing 180,000 tons of polypropylene a year. Since 2001, we have been producing the entire volume of propylene, the raw material for polypropylene, from the Residue Fluid Catalytic Cracking (RFCC) Unit process.
