Yanchang Petroleum plans to build a 5 million tons/year CCUS facility

CO2 emissions from the coal chemical and power industries in the Yulin region are indeed extremely high.

Recently, China’s first million-ton-scale CCUS (carbon dioxide capture, utilization, and storage) project – the Qilu Petrochemical-Shengli Oilfield CCUS project owned by Sinopec – was fully completed. Once the project is in operation, it will enable the reduction of 1 million tons of carbon dioxide emissions per year, which is equivalent to planting nearly 9 million trees or stopping nearly 600,000 economy cars from running for a year. It is expected that over the next 15 years, an increase of 2.965 million tons in crude oil production will be achieved. This is currently the largest CCUS full-industry chain demonstration base and model project in China. It serves as a significant model for the large-scale development of CCUS in the country, and it is of great importance for establishing a \"human-made carbon cycle\" model and enhancing China’s capacity to reduce carbon emissions. CCUS is one of the key technologies for reducing carbon dioxide emissions; it involves capturing and purifying the carbon dioxide emitted during production processes, and then reusing or sequestering it in new production processes, thereby directly reducing carbon dioxide emissions. China possesses substantial petroleum geological reserves suitable for carbon dioxide flooding, and accelerating the development of the CCUS industry can provide strong technical support for ensuring **energy security. Furthermore, as an essential technological pathway to achieve carbon neutrality, CCUS possesses tremendous emission reduction potential and broad prospects for industrial application. Research shows that in the future, China will need to rely on CCUS to offset more than 1 billion tons of carbon emissions, which can effectively promote the cleaner use of fossil fuels, the larger-scale use of clean energy, and lower carbon emissions in production processes. Construction of this project began in July 2021, and it consists of two components: carbon dioxide capture at Qilu Petrochemical and carbon dioxide flooding and sequestration at Shengli Oilfield. The carbon dioxide captured by Qilu Petrochemical is transported using green methods to the Shengli Oilfield for oil displacement and sequestration, enabling an integrated approach to carbon dioxide capture, oil displacement, and sequestration. This process involves sealing the carbon dioxide underground while displacing the oil, thus turning waste into a valuable resource. In the field of carbon capture, Qilu Petrochemical has built a new facility with an annual capacity of 1 million tons for the recovery and utilization of liquid carbon dioxide, which is used to extract carbon dioxide from the exhaust gases generated by coal-based hydrogen production units; the purity of the recovered carbon dioxide can reach over 99% after purification ； In terms of carbon utilization and sequestration, Shengli Oilfield takes advantage of the fact that supercritical carbon dioxide can mix easily with crude oil; it has built 10 unattended gas injection stations to inject carbon dioxide into 73 nearby wells, thereby increasing the fluidity of the crude oil and significantly raising its recovery rate. Meanwhile, the oil and gas transportation systems utilize closed pipeline systems, which further enhances the rate of carbon dioxide sequestration. “During the 14th Five-Year Plan period, Sinopec will intensify its efforts in this area, working to establish research and development centers for carbon capture, utilization, and storage technologies. It aims to develop an innovation system for carbon dioxide utilization that encompasses technology development, engineering demonstrations, and industrial application, thereby expanding the clean carbon sequestration industry chain. The goal is to create hubs for innovation in carbon reduction technologies, and to set up another hundred-thousand-ton-scale CCUS demonstration project, thus promoting the industrialization of CCUS and opening up broader prospects for China to achieve its \"dual carbon\" goals.

Not bad, not bad; it’s also possible to purify part of the carbon dioxide and use it in hydrogenation to produce methanol – it’s not necessary to inject all of it underground.

I am also looking for technologies for the utilization of CO2; if you know any, please let me know. Thank you

Will Sinopec Petroleum Engineering Design Co., Ltd. end up in the same situation as Shengli Oilfield?
