Conservation

PetroChina Daqing Petrochemical Company actively advances low‑carbon transformation through technical innovation. It has built CNPC’s first 400 kt/a high‑concentration CO₂ recovery unit, capturing by‑product carbon dioxide for oil displacement in Daqing Oilfield. Meanwhile, waste‑gas recycling facilities such as catalytic dry‑gas C₂‑recovery unit are operational to reclaim high‑value hydrocarbon components from exhaust gas, realizing resource reuse and emission reduction simultaneously. The company also deploys water‑surface photovoltaic projects, consuming large‑volume green power for production processes to cut fossil‑energy reliance.
