PetroChina's Dushanzi Petrochemical Tarim unit completed initial feed and start-up of its phase‑II 1.2 mln t/yr ethylene plant and accompanying green low‑carbon demonstration facilities and has begun commercial operations. The project—China's refining-and-chemicals industry's first full‑chain green low‑carbon ethylene scheme and the world's first ethylene‑cracking carbon‑emissions recycling demonstration base—establishes central/west China's first ~3 mln t ethylene industrial hub, shifting some

PetroChina's Dushanzi Petrochemical Tarim unit completed initial feed and start-up of its phase‑II 1.2 mln t/yr ethylene plant and accompanying green low‑carbon demonstration facilities and has begun commercial operations. The project—China's refining-and-chemicals industry's first full‑chain green low‑carbon ethylene scheme and the world's first ethylene‑cracking carbon‑emissions recycling demonstration base—establishes central/west China's first ~3 mln t ethylene industrial hub, shifting some domestic ethylene capacity away from the eastern concentration and enhancing national energy‑chemical supply‑chain resilience.
