GS CALTEX BUSINESS — CHAPTER 01
From 800,000 barrels a day to everyday energy —
the world's no.4 single refinery. The story begins in Yeosu.
Founded in 1967 as Korea's first private refiner, GS Caltex still turns crude from across the sea into everyday energy.
01 — CRUDE SOURCING
Crude arrives from over 30 countries in more than 80 grades. Sourcing that leans on no single region spreads the purchasing risk.
Light and heavy, sweet and sour — handling crudes of every character is the first condition of stable supply.
02 — DISTILLATION
Heated past 360°C and fed into the column, the lighter a fraction boils, the higher up it is drawn off. One crude separates into layers of products.
02 — CAPACITY
The daily crude capacity of the Yeosu complex — where gasoline, kerosene, jet fuel and diesel are made.
WORLD NO.4 · SINGLE REFINERY03 — UPGRADING
Distillation is not the end. The cheap residue at the bottom is cracked again into high-value light products — in Korea's largest upgrading complex.

04 — TO EVERYDAY LIFE

The journey of a drop of crude does not end here. The feedstocks born in refining carry on — into aromatics, olefins and polymer, deeper into chemistry.
