In gas processing the company completed a plant in Thailand in 2010 that it describes as the world's largest at the time, then moved into gas oil separation through the Sabah Oil & Gas Terminal in Malaysia, Saudi Aramco's Shaybah NGL project and the West Qurna project in Iraq. Current gas references include Saudi Aramco's Fadhili Gas Increment Program and the Jafurah Gas Processing Facility, which the company expects to complete in 2026. In refining, the Dos Bocas refinery for PEMEX in Mexico was awarded in 2020 at KRW 4.5 trillion, the largest contract in the company's history.

Low-carbon projects and partnerships

Sustainable energy covers green hydrogen, green ammonia and e-fuels such as e-SAF and e-methanol, together with low-carbon fuels and chemicals from waste and biomass, and carbon management including capture, utilisation and storage, blue hydrogen and blue ammonia. Awards recorded in 2025 include the WVR Hydrogen Energy Center in the United States, where construction started in 2026, a FEED contract for the DG Fuels sustainable aviation fuel plant in the United States, the INPEX Abadi onshore LNG FEED in Indonesia, the Emirates Biotech Falcon PLA pre-EPC package in the United Arab Emirates and the ADNOC TA'ZIZ methanol project. Earlier low-carbon awards were the PBSB Phoenix biorefinery in Malaysia in 2024, the company's first sustainable aviation fuel project, and ethylene storage facilities in Qatar the same year.
