(碳捕集与封存)Carbon Capture and Storage Technology

Transportation
The captured carbon dioxide must be transported to the proper place for storage and can be transported using cars, trains, ships and pipes. Generally speaking, pipelines are the most economical means of transportation.
Ocean Storage（海洋封存）
• Ocean mothballed means that CO2 is transported to the seabed by ship or pipes.
Global Development Status
According to Reuters, the global carbon capture and storage in the annual report on global deployment of carbon capture and storage condition warned about
Oxy-fuel combustion
Post-combustion Capture
investment levels and regulatory uncertainty. By now,
from the current 16 items surged to 130 projects goal
is impossible of achievement.

Definition
Carbon Capture and Storage (缩写为CCS，即碳捕集与封存) refers to a kind of technology that the Carbon dioxide (CO2) generated by the large power plants are collected and use various methods to be stored in order to avoid their emissions to the atmosphere.

Capture
Βιβλιοθήκη Baidu
Pre-combustion Capture（燃烧前捕集）
• Low energy consumption, great potential, high cost of investment
Oxy-fuel combustion（富氧燃烧）
• High energy consumption, high cost of investment
Post-combustion Capture（燃烧后捕集）
• Highly applied, large collection system, high energy consumption Industrial flow diagram
Sequestration
Geological Storage（地质封存）
• Geological sequestration is generally the supercritical state (mixture of gas and liquid) of CO2 injection of geological structure, the geological structure can be oil field, gas, salt water layer, unable to mining of coal, etc.
