OIL REFINING BUSINESS Overview & Facility

Overview

S-OIL is leading the oil-refining business through high valuing of products along with the optimization of all oil refinery production facilities.

Since S-OIL began the commercial operation of its 1st oil refinery with a capacity of 90,000 barrels/day in 1980, it has expanded facilities on two occasions, and today, S-OIL is a large oil refining company with a refining capacity of 669,000 barrels/day. In addition, in line with such achievements, the company operates light oil desulfurizing facilities and gasoline manufacturing facilities.

S-OIL has been operating its Bunker-C Cracking Center (BCC), which is a large upgradability facility for replacement and low sulfurization of all products that actively respond to change in market conditions, such as environment regulation strengthening and product consumption, increase of hard oil in the local and overseas market since the 1990s, ahead of other oil refinery companies.
The BCC extracts expensive hard oil from inexpensive high-sulfur bunker-C, and changed the history of oil refinery industry by changing from the local oil refinery industry of the past that was only acknowledged as a simple production company, to a high-value exportation industry.
This facility is a new concept high-tech processing facility that increased the handling amount while maintaining relatively low costs. The facility is composed of a Hydrocracking Complex, the 1st state facility, and the Residue FCC Complex, the 2nd facility.

S-OIL

Also, by operating New Hyvahl , which is the high-tech enhancement facility of high value, S-OIL started to increase competitiveness in Korea and around the world. Due to the operation of this facility, S-OIL stands high as the leading oil-refinery company, while achieving high valuing of products and optimization of all production facilities.

Exportation to Overseas Market

In the past, the oil refinery industry was generally known for having facilities to fulfill domestic demand, but S-OIL focused on pioneering the overseas market from the beginning. Based on the Bunker-C Cracking Center (BCC) in the global-standard enhancement facility, the company plays an important role as the hub of hard oil provision in the Asia-Pacific area.
S-OIL started to export environment-friendly and high-value Ultra Low Sulfur Diesel (ULSD) of below 50ppm sulfur contents to Hong Kong in January 2001, and also started exportation to Japan from May of the same year.

From January 2005, the company started to export Ultra Low Sulfur Gasoline (ULSG) of below 10ppm sulfur contents to Japan, with strict environmental regulation. The ULSD of below 10ppm sulfur contents are concentrated in the creation of high value in the overseas market through production and exportation of high quality environment-friendly oil products to countries around the world including those in Asia, U.S., Europe, and Oceania.

Facility

Crude Distillation Unit

This unit proaduces LPG, naphtha, kerosene/diesel, B-C oils and other products from crude oil. Since S-OIL first began the commercial operation of its 1st crude oil distillation unit with a capacity of 90,000 barrels/day in 1980, it expanded facilities on two occasions. S-OIL is now ideally positioned as a highly competitive oil refining company with three crude distillation units with 669,000 barrels/day of total capacity.

B-C Cracking Center

The Bunker-C Cracking Center(BCC) is a facility which produces high value-added light oil products like gasoline, diesel and kerosene, by using as feed the Bucker-C oil that remains after extracting light oils from crude oil at the atmospheric distillation unit. The BCC is often called the “ground oil field” because it creates more value than drilling for crude oil does.
The BCC consists of Bunker-C cracking units and desulfurization units. The Bunker-C cracking units crack high-sulfur Bunker-C oil through the use of hydrogen or catalyst to produce light oil products. The desulfurization units remove sulfur and other impurities, thereby increasing the value of products and eliminating the Ccause of environmental pollution.
