Lummus Commends S-OIL on Groundbreaking for Shaheen Crude-to-Chemicals Complex

Next stage in one of the world’s largest ethylene plants and first commercial
deployment of TC2C, which maximizes conversion of crude oil at a lower
carbon intensity and higher energy efficiency
HOUSTON, March 24, 2023 – Lummus Technology, a global provider of process technologies and value-driven energy solutions, today commended S-OIL for breaking ground on the Shaheen project in South Korea. The Shaheen project reached a final investment decision in November 2022. Once complete, the Shaheen complex will include one of the world’s largest ethylene steam crackers and the first commercial deployment of TC2C, a technology that converts whole crude into value-added chemicals.
“We are excited to celebrate S-OIL’s next step in the Shaheen project, which will transform petrochemical production and transition to more sustainable processes,” said Ron Venner, Chief Business Officer of Clean Fuels and Crude to Chemicals, Lummus Technology. “In implementing TC2C, S-OIL will be able to adapt to the evolving petrochemical market demands for diversified and cleaner feedstocks, reduce their carbon footprint and increase the energy efficiency of their operations.”
S-OIL’s new plant will deploy several Lummus and Chevron Lummus Global (CLG) technologies to process crude to produce ethylene, propylene, butadiene and other basic chemicals. Upon completion, the new plant will have an annual production capacity of up to 3.2 million tons of petrochemicals.
TC2C converts crude into value-added chemicals in a uniquely integrated process combining Lummus’ ethylene technology with Saudi Aramco’s separation and catalyst technologies and CLG’s hydroprocessing catalysts and reactor technologies. TC2C maximizes conversion of crude at lower carbon intensity, higher energy efficiency and lower capital than conventional refinery/petrochemical complexes. Unlike any other crude-to-chemicals technology, TC2C processes low-value refinery streams such as slurry oil and pyrolysis oil, and it can be tailored to maximize olefins, aromatics or any combination.
Saudi Aramco is the majority shareholder of S-OIL. In 2018, Saudi Aramco Technologies Company, Lummus and CLG entered into the joint development agreement for the development, commercialization and marketing of TC2C.
