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 2,400 service stations, 400 filling stations, various factories, and railway and airline operators.
GS Caltex is also a major exporter. We process crude oil imports into petroleum products which are exported around the world.
Heavy Fuel Oil
Economical and efficient fuel
Heavy fuel oil is the blackish brown viscous fluid that remains after processing crude oil. GS Caltex produces bunker C (B-C) oil, which is mainly supplied for large industrial boilers. B-C oil has high caloric value and low prices but is difficult to handle. We also supply bunker A (B-A) and bunker B (B-B) oil, obtained by mixing in light crude oil. B-A is mainly used in small industrial boilers and small to mid-size ships, while B-B is used in mid-size boilers and mid-size ships.
Precautions for users
Owing to high kinematic viscosity, heavy fuel oil will readily solidify at room temperature and must be pre-heated to about 50℃ for storage and use. When kept in storage tanks, the difference with the outside temperature may cause condensation to occur and the moisture to settle at the bottom. As such, a drain line must be installed so that water at the bottom of the tank can be regularly removed.
