Sinopec's New Plan to cut 1m tons carbon emissions per year
BEIJING, Jan. 31, 2022 — China Petroleum & Chemical Corporation (HKG: 0386, Sinopec) has completed the construction of China’s first megaton carbon capture, utilization and storage (CCUS) project, the Qilu-Shengli Oilfield CCUS on January 29.
It will reduce carbon emission by 1 million tons per year, the equivalent of planting nearly 9 million trees and shutting down 600,000 economy cars.
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 million tons 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.
The construction of the Project was initiated in July, 2021 and is consisted of two parts – Sinopec Qilu’s carbon dioxide capture and Shengli Oilfield’s carbon dioxide displacement and storage.
The carbon dioxide 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 carbon dioxide underground and drive the oil out – turning the waste into treasure.
Sinopec Qilu has newly constructed a liquid carbon dioxide recovery and utilization unit with a capacity of 1 million tons per year. it includes compression unit, refrigeration unit, liquefaction refining unit and supporting facilities to recover carbon dioxide from the tail gas of coal-to-hydrogen plant with a purification rate of over 99 percent.
Meanwhile, Shengli Oilfield is applying the principle of supercritical carbon dioxide’s easy miscibility with crude oil to build 10 unattended gas injection stations in Zhenglizhuang Oilfield.
The plan is to inject carbon dioxide into the 73 wells nearby to increase crude oil fluidity. It will also improve oil recovery while adopting closed pipeline transportation of oil and gas to further enhance the carbon dioxide 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.
More projects
Backed by systematic investigation of China’s large-scale carbon dioxide 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 carbon dioxide 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 carbon dioxide production of high-value chemicals and carbon dioxide mineralization and utilization to make breakthroughs in the core technologies and solving the equipment bottlenecks in carbon capture, transportation, utilization and storage.
With the goal of building a carbon dioxide technological innovation system of “technology development-construction project demonstration and industrialization,” Sinopec will extend the clean carbon sequestration industrial chain and build the foundation for carbon emission reduction technology innovation.
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.
