Tarim Low Carbon Ethylene Project

China National Petroleum Corporation put into operation the Tarim 1.2 MMtpy Phase II Ethylene Project and its supporting green and low-carbon demonstration facility in Korla. It directly uses renewable energy generated by Tarim Oilfield's photovoltaic facilities, with around 1 billion kilowatt-hours of green electricity supplied to the complex each year. It has also completed the construction of the world's second and China's first domestically developed electric-driven system for the three major ethylene compressors, shifting from thermal to electric power. In addition, it has adopted a first-of-its-kind integrated carbon capture technology in China to recover low-concentration carbon dioxide from cracking furnace flue gas that would otherwise be emitted into the atmosphere. The captured CO₂ and recovered byproduct hydrogen are reused in the production process, forming a closed-loop low-carbon industrial chain that connects green power, carbon capture, blue hydrogen, blue ammonia and lower-carbon fertilizer production.
