Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a carbon dioxide resource disposal system and method. Background technique [0002] At present, 80% of the world's energy comes from fossil energy such as coal, oil and natural gas. The use of fossil energy will emit a large amount of carbon dioxide. In recent years, global warming has become more and more serious, and carbon dioxide is considered to be the "main cause" of climate warming. In the face of increasingly urgent environmental problems, carbon capture and storage (CCS) technology has emerged. CCS technology refers to the capture and separation of carbon dioxide from related emissions and combustion sources, and transports it to oil and gas fields, oceans and other places for long-term (thousands of years) storage. ) storage, thereby preventing or significantly reducing the emission of greenhouse gases to mitigate the impact on the Earth's climate. ...
