Business Overview

Refinery production

GS Caltex imports 80 types of crude oil from some 30 countries spread across the Middle East, US, Southeast Asia, Australia and Europe. Diversified sourcing ensures a stable supply. We produce high-quality petroleum products using our refining capacity of 800,000 barrels per day (bpd) and cutting-edge production systems that include facilities to desulfurize kerosene and diesel.

Additionally, heavy oil upgrading(HOU) facility, the largest in the nation, has a capacity of 275,000 bpd and produces light oil products and high-grade gasoline. It has brought GS Caltex a step closer to realizing a ‘perfect complex.’

Link to Production Process

Supplying Korea’s oil needs and exporting petroleum products

Our petroleum products provide a stable supply to satisfy home demands for industrial and transportation purposes across Korea. They are shipped to about 2,200 service stations, 340 filling stations, various factories, and railway and airline operators. (AS of the end of 2023)

GS Caltex is also a major exporter. We process crude oil imports into petroleum products which are exported around the world.

Asphalt

Paving the roads in Korea and around the world

GS Caltex produces top-quality asphalt using technology accumulated from continuing R&D. We started off with domestic shipments in 2000. Thanks to growing recognition of product quality, we also export asphalt to China and Southeast Asia. We have annual production capacity of 25,000 BD (domestic shipment: 8,000 BD, exports: 17,000 BD).

Evolution of asphalt, PMA

We offer urban-friendly polymer modified asphalt (PMA) based on technology developed internally. PMA overcomes the shortcomings of conventional asphalt.

Our PMA products are made by adding styrene-butadiene-styrene (SBS) copolymer and special catalyst to regular asphalt to set off a physicochemical reaction. (SBS copolymer is a thermoplastic elastomer bearing properties of rubber and two types of plastics.) They have greater durability and resilience than conventional asphalt and a longer service life (extended from 10 years to 12~15 years). Our products also offer improved penetration index and reduced pavement noise.

PMA Production Process
  1. Conventional asphalt
    Stage 1
    • Property measurement: penetration index, softening point
    • Component analysis: aromatics, asphaltene
  2. SBS, Additive Mixing vessel
    Stage 2
    • Properties of SBS, SBS and additive blending ratio
    • Reaction temperature and time

Revolutionizing roads, regular asphalt

Asphalt is used for paving roads and is produced during the process of refining crude oil. It is a raw material for making asphalt mixtures (asphalt + aggregates). Asphalt is solid at low temperature (below 0℃), viscoelastic at room temperature (0~100℃) and liquid at high temperature (100℃).
