Definitions
- the present invention relates to a land-based carbon dioxide capture and carbon resource recovery system that can remove carbon dioxide and at the same time convert it into other useful materials by capturing and converting carbon dioxide in exhaust gas using a basic alkali mixture into a carbon resource.
- Earth's climate change is represented by glacial periods and interglacial periods periodically by changes in the orbital axis, cycles in which the angle of the axis of rotation changes, precession cycles, and solar radiation. is increasing in degrees Celsius.
- the average temperature has risen by 0.74°C over 100 years, which is 7 times higher than the increase in temperature due to natural phenomena, which can be attributed to artificial phenomena caused by human activities.
- Global warming is expected to bring about great disasters to mankind by causing disturbances in the global ecosystem, such as sea level rise, famine, outbreaks of diseases such as malaria, and changes in water shortages as the global temperature rises.
- carbon dioxide is designated as a greenhouse gas that causes global warming, and although the global warming potential of carbon dioxide is lower than that of other greenhouse gases, it accounts for 80% of the total greenhouse gas emissions and the emission can be regulated.
- IMO International Maritime Organization
- EEDI Ship Energy Efficiency Design Index
- CCS carbon dioxide capture and storage
- Carbon dioxide capture and storage (CCS) technology is a technology that captures, transports, stores, or converts (immobilizes) greenhouse gases emitted from fossil fuel combustion. This technology can effectively reduce CO 2 emissions and is being considered as a realistic alternative that will serve as a bridging technology until the economic feasibility of new and renewable energy is secured.
- CCS is mainly used to reduce carbon dioxide generated in the process of power generation using coal and gas, but it is also applied to carbon dioxide intensive industries such as cement, steel, petrochemical, and oil and gas production.
- Storage methods include geologic storage, marine storage or other storage methods such as storage in minerals.
- marine storage is currently prohibited due to concerns that it will pose a high environmental risk.
- Storage in minerals is currently the subject of research, but technological developments such as energy use reduction and large-scale reduction technology improvement are still needed.

- the onshore carbon dioxide capture and carbon resource recovery system includes a monitoring unit for monitoring the water level and pH of the basic alkali mixture in the absorption tower; and a controller controlling the supply amount of the basic alkali mixture by the monitoring unit.
- the carbon dioxide reactant may include sodium carbonate (Na 2 CO 3 ) or sodium hydrogen carbonate (NaHCO 3 ).
- the land carbon dioxide capture and carbon resource recovery system can reduce carbon dioxide by capturing carbon dioxide from exhaust gas discharged from land such as thermal power plants, LNG, LPG or fuel cell facilities, and using the collected carbon dioxide to reduce sodium carbonate. Alternatively, it can be recycled into other useful materials by recycling carbon as sodium bicarbonate.
