China's first maritime carbon dioxide sealing (CCS) demonstration project is officially put into use in the eastern part of the South China Sea, and it has begun to inject carbon dioxide into the seabed strata.
According to Caixin.com, China Oil Group announced the above information on Thursday (June 1).
CCS is one of the carbon capture, utilization and sealing (CCUS) technology, that is, separate carbon dioxide from the process of power generation, chemical, steelmaking, etc.In the geological body such as coal beds and salt beds, thereby sealing the carbon dioxide process.The above project is to seal the carbon dioxide produced by oil production platform with Enping 15-1.
It is reported that Ensing 15-1 platform is the largest maritime crude oil production platform in Asia. The oil fields are in the peak of the oil fields and Nissan crude oil of more than 7,000 tons.It will not only increase the amount of carbon dioxide emissions, but also corrode the maritime platform facilities and underwater pipelines.
The goal of this project is to achieve "shore carbon entering the sea", that is, to capture carbon dioxide emitted on land, and transport or seal them in the ocean through tankers, pipelines, ships, etc.According to China Sea Oil, carbon dioxide emissions in southern China and coastal areas are high, but the area of land deposition basins in these areas is small and scattered in distribution, which is not suitable for sealing; and marine carbon sealing has not occupied land, stay away from water storage layer, seawater blocks, etc.Advantage.
