direct air capture
Climate change on the planet is the most important problem that the scientific community is solving. Methods are being developed to capture carbon from the atmosphere, soil and water.
The man-made consequences of human activity are increasing and the oceans, atmospheric air, and soil are the main accumulators of harmful substances.
One of the main problems of human activity is the constant increase in carbon dioxide emissions. To limit the effects of climate change, technologies are needed to sequester CO2 from the atmosphere, seas, and soil.
The main problem for extracting CO2 from atmospheric air and water is the energy intensity of the extraction processes. Capturing CO2 requires moving large currents of air or water.
We offer simple solutions for the complete autonomy of devices for capturing CO2 from atmospheric air and seawater.
To achieve this goal, we propose to use the entire range of renewable energy sources. The capture of CO2 is carried out by the method of physical absorption, that is, the passing air stream is sprayed with liquid, absorbs CO2, and then extracted in the degassing chamber.
Basic principles of creating conditions for air convection.
- – Draft in the chimney;
- – Coating the surface of the duct with a material that absorbs solar energy for heating;
- – Placement of a circular concentrator on a vertical duct;
- – Creation of a pressure drop in the duct due to the use of diffusers such as the Laval nozzle;
- – Use of a wind generator to create the mechanical movement of air and generate electrical energy;
- – The use of solar panels for the production of electrical energy.
