MOSCOW (MRC) -- Sinopec revealed it has completed the construction of China's first megaton CCUS project, the Qilu-Shengli Oilfield CCUS. The project will reduce carbon emissions by 1 MMtpy, said Hydrocarbonprocessing.
As China's largest full industrial chain CCUS demonstration base and industry benchmark, the Project is estimated to increase the oil production by 2.965 MMt in the next 15 years. It's of great significance to China's scaled development of CCUS and building an "artificial carbon cycle" model to increase China's carbon emissions reduction capabilities as the country advances to achieve the "dual carbon" goals of reaching peak carbon emissions by 2030 and carbon neutrality by 2060.
Construction of the project was initiated in July 2021 and is consisted of two parts – Sinopec Qilu's CO2 capture and Shengli Oilfield's CO2 displacement and storage. The CO2 captured by Sinopec Qilu will be transported to Shengli Oilfield for further displacement and storage via green transport mode, achieving an integrated application of carbon capture, displacement and storage to seal the CO2 underground and drive the oil out – turning the waste into treasure.
Sinopec Qilu has newly constructed a liquid CO2 recovery and utilization unit with a capacity of 1MMtpy, which includes compression unit, refrigeration unit, liquefaction refining unit and supporting facilities to recover CO2 from the tail gas of coal-to-hydrogen plant with a purification rate of over 99%.
Meanwhile, Shengli Oilfield is applying the principle of supercritical CO2's easy miscibility with crude oil to build 10 unattended gas injection stations in Zhenglizhuang Oilfield to inject CO2 into the 73 wells nearby to increase crude oil fluidity and improve oil recovery while adopting a closed pipeline transportation of oil and gas to further enhance CO2 sequestration rate.
Taking an early start of CCUS R&D and construction, Sinopec has developed its own CCUS technology system that has achieved good results in improving crude oil recovery and reducing carbon emissions, and some of the capture technologies is in leading position domestically and advanced level in the world.
Backed by systematic investigation of China's large-scale CO2 emission sources, Sinopec has researched and drafted the CCUS potential evaluation method and established the Sinopec source & sink database. To date, Sinopec has implemented 36 CO2 flooding projects.
Sinopec is looking to advance the constructions and realize the industrialized development of CCUS. Sinopec will build a CCUS R&D center to focus on the cutting-edge technological breakthroughs including the integration of CCUS with new energy, hydrogen energy and biomass energy. The company will advance the technology applications such as the CO2 production of high-value chemicals and CO2 mineralization and utilization to make breakthroughs in the core technologies and solving the equipment bottlenecks in carbon capture, transportation, utilization and storage.
Between 2021 and 2025, Sinopec will build another megaton CCUS demonstration project in partnership with Sinopec Nanjing Chemical Industries Co., Ltd. in its affiliated Sinopec East China oil and gas fields and Sinopec Jiangsu Oilfield to achieve the industrialized development of CCUS and widen the prospects as China advances to achieve carbon peak and carbon neutrality.
Sinopec has set up a separate company to work on projects in the field of alternative energy sources. The authorized capital of the company, which received the name Zhongshihua Xiongan Xinnenyuan (Zhongshihua Xiong'an Xinnengyuan), amounted to 100 million yuan (USD15.7 million). Li Yutian has been appointed as its legal representative.
Earlier it was reported that SIBUR, the largest petrochemical complex in Russia and Eastern Europe, and the Chinese petrochemical giant - Sinopec - raised project financing for the Amur Gas Chemical Complex (GCC) from a syndicate of international, Chinese and Russian banks for a total of USD9.1 bn.
Sinopec Corp. is one of the world's largest integrated energy and chemical companies. Business of Sinopec Corp. includes oil and gas exploration, production and transportation of oil and gas, oil refining, petrochemical production, production of mineral fertilizers and other chemical products. In terms of oil refining capacity, Sinopec Corp. ranks second in the world, and fourth in terms of ethylene capacity.
