Background of Sinopec CCS
The great threaten for environment
• CCS is an effective way to reduce greenhouse gas
emission
• China is going to reduce the intensity of CO2 emissions
per unit of GDP in 2020 by 40 to 45 percent compared with
the level of 2005.
• China carries out a series of policies to promote CCS
• The social and environmental responsibilities
• Having CO2 capture resources(refineries, natural gas
with high CO2 content, plant, etc.)
• Having a vast amount of reservoirs suitable for CO2–
EOR and storage, CCS+EOR
Global warming
