Report from Zibo, December 11. Today, the civil construction of the Qilu Petrochemical-Shengli Oilfield CCUS (Carbon Capture, Utilization and Storage) project has been completed. Subsequently, the frame steel structure welding, equipment installation, and pipeline construction will be carried out. The device is expected to be handed over by the end of December. This project is the first million-ton CCUS project in China. Once completed, it will become the largest CCUS full industry chain demonstration base in China. At the project tank farm construction site, there are two newly assembled and welded spherical tanks, each of which can store 4,000 cubic meters of carbon dioxide. “In the carbon capture process, the recovery and purification device we built will recover the carbon dioxide in the exhaust gas of the coal-to-hydrogen production unit, and the purity after purification will reach more than 99%. ”Xu Qixuan, deputy manager of the Science and Technology Development Department of Qilu Petrochemical, told reporters that after the project is completed, it will reduce carbon dioxide emissions by 1 million tons per year, which is equivalent to planting nearly 9 million trees or stopping nearly 600,000 economical cars for one year. It is understood that the carbon dioxide produced by Qilu Petrochemical is captured and purified and then transported to Shengli Oilfield for oil flooding and storage. This not only achieves energy conservation and emission reduction, reduces the impact of greenhouse gases on the environment, but also increases the oil field recovery rate and significantly increases the recoverable reserves of the oil field. It is estimated that in the next 15 years, Shengli Oilfield can inject more than 10 million tons of carbon dioxide cumulatively, achieving an oil increase of nearly 3 million tons.
