S-OIL to produce bio-based, low-carbon products
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 has three crude distillation units with 669,000 barrels/day of total capacity (photo courtesy S-OIL).

In South Korea, oil refiner and petrochemical company S-OIL Corporation (S-OIL) has announced that it has started to include bio-based feedstocks such as used cooking oil (UCO), byproducts of the palm oil, and waste plastic-based pyrolysis oil into the refining and chemical processes to produce low-carbon energy and eco-friendly chemical products.

As it will co-process crude oil, bio-based feedstocks, and waste plastic-based pyrolysis oil in the existing refining process, it will produce biofuels with low carbon intensity such as sustainable aviation fuel (SAF) and next-generation renewable diesel as well as bio-based petrochemical feedstocks such as naphtha and polypropylene.

According to the company, the incorporation of bio-based feedstocks into the refining process is a first for a refiner in South Korea.

This comes after the approval for the demonstration of the co-processing of waste plastic-based pyrolysis oil in July 2023, and bio-based feedstocks in December 2023 under the government’s regulatory sandbox program, a special deregulation program.

S-OIL has now started to use the feedstocks after promptly completing preparatory work such as the installation of feedstock injection facilities.

It plans to expand the volume of eco-friendly products by assessing yield changes in the product portfolio and the impact on the production processes while adjusting the mix ratio of new alternatives such as bio-based feedstocks and waste plastic pyrolysis oil over the next two years.

To keep pace with the global decarbonization trend, S-OIL signed a partnership with Samsung C&T to develop new businesses on hydrogen and biofuels in 2021 and sealed a partnership with Dansuk to build supply chains of eco-friendly, low-carbon fuels and chemical feedstocks last December.

The company will seek International Sustainability and Carbon Certification (ISCC) of fuels produced from alternative feedstocks to accelerate green energy and chemical businesses and will also specify their carbon reduction effect, thereby contributing to the government’s green energy policies and building a circular economy, said S-OIL in a statement.
