Reverse Fractionation System for Carbon Capture

At present, United Nation climate change models assume climate change is irreversible as there is no means by which large volumes of CO2 can be extracted from the atmosphere. The present reverse fractionation system for carbon capture addresses this problem and can reverse climate change economically.

Conventional reverse fractionation systems have not been considered as a viable option for carbon capture due to the energy required to cool air down to low levels would produce more CO2 than it would capture resulting in a net output of Carbon Dioxide.

The present system addresses this by cooling down the gas, condensing the gas and extracting the heat released by the latent heat of fusion thereby resulting in a net absorption of CO2 which can then be used for food processing, carbonation of fizzy drinks and even conversion into calcium carbonate for industrial processes, increasing plant yield in greenhouses or the conversion of fuel via hydrogenation or polymerization. Greenhouse yield increases where plants are exposed to a higher concentration of CO2 than available in air.

The technical advancements of present reverse fractionation system model are enumerated hereunder: 

Net absorption of CO2:

Net absorption of CO2 takes place in the present reverse fractionation process. The invention addresses this by utilising the latent heat of condensation to power the cooling thereby resulting in a net absorption of CO2.

Suction fans not required:

The Present System does not rely on suction fans to create negative pressure to draw in air. Instead, the contraction of water vapors and when it liquifies and contraction of CO2 when it solidifies (CO2 sublimates) plus the contraction in air volume when air is cooled results in a large negative pressure in the reverse fractionation system. Water vapors when it condenses to liquid water contracts in volume by 1600 times its original volume. Carbon dioxide gas when it condenses to a solid, which contracts by 540 times its original volume. This would mean that 2140 liters of water vapors and gaseous carbon dioxide would shrink to 1 liter in volume. This in turn would lead to a massive negative pressure in the reverse fractionation system leading to air being drawn into the fractionation funnels without the need for physical fans to create negative pressure with the commensurate parasitic loss in energy.

CO2 capture with energy production:

The air temperature differential towers that are absorbing energy from the air (climate change is mitigated as the system converts heat to electricity) and the present invention is absorbing a large volume of air across the heat exchanger by the forward motion of the vehicle, and this results in a large energy gain inside the energy collection unit from ambient air temperatures.

Utilization of Captured CO2 for electricity production:

One ton of CO2 and H2O captured will generate 22 KWH of energy via the SSCCO2T turbines.
