Petrochemical Business Overview & Facility

Overview

S-OIL has the best competitiveness in the petro-chemistry area, along with the lubricant and oil refinement area, through business diversification.

For continuous growth, S-OIL put effort into increasing the value of manufactured products. As a result, by commercially operating the BTX production facility and Naphtha Reforming Plant in April 1991, a base for business diversification in the petro-chemistry area was provided.

Also, for the single process within existing factory land in December 1997, the Xylene Center that produces Para-Xylene of 700,000 tons (currently 740,000 tons) was completed and the company officially entered the petro-chemistry area. In particular, this factory did not only reduce the investment burden per unit, but the petro-chemical products from the BTX process were Para-Xylene, which has high competitiveness from the perspective of material fees.

Petrochemical Business

In this way, the Residue Fluidized Catalytic Cracker (RFCC) started to produce 200,000 tons of propylene in April 1997 and expanded the business area of petroleum. This was an opportunity to provide the foundation to acquire competition superiority in the petro-chemistry downstream sector.

S-OIL reformed its crude oil refining process and built its 2nd Xylene center that produces Para-Xylene, which is the base material of compound fiber, in April 2011. Subsequently, the 2nd Aromatic Complex composed of the aromatic facility that produces BTX was completed. Through the operation of this facility, S-OIL possessed the best competiveness in the petro-chemistry area, following the lubricant area and oil refining area, while simultaneously possessing a 600,000 ton Benzene production facility and 1.7 million ton Para-Xylene production facility.

S-Oil did not stop here, and is promoting entrance to the Olefin Downstream Business through its RUC/ODC Project. The successful completion of RUC/ODC aimed for 2018 will provide the groundwork for a vision of S-OIL as 'The most competitive and admired energy & chemical company in Asia Pacific' along with expansion in the petro-chemistry area.

Facility

BTX Plant

The BTX Facility produces aromatic petro-chemistry products such as Benzene, Toluene, and Xylene by adding Naphtha.
The company sets a basis for business diversification in the petro-chemistry area of S-OIL.

BTX Plant : Product, Facility capacity, Date of commercial operation Table.
Product Facility capacity commercial operation
Benzene 150,000 ton/year 1991.04
Toluene 350,000 ton/year
Xylene 450,000 ton/year
BTX Plant

Xylene Center

The Xylene Center produces Para-Xylene, which is a base material of compound fiber, by adding C9+ as material and BTX product including Xylene and Toluene.
The raw materials from the existing BTX factory are applied stably for advantage in economic feasibility such as a reduction in production cost.
