Benefits of technology

The present invention is about a method and apparatus for capturing carbon dioxide from air. The technical effects of this invention include efficient capture of carbon dioxide from air at a later time, as well as balancing out carbon dioxide emissions from vehicles. The invention uses a sorbent that can absorb carbon dioxide, processes that heat or cool the air, or that change the pressure of the air by substantial amounts to effect the capture. The invention also includes a design for the apparatus that provides straight flow paths for the air, with smooth surfaces that can be easily wetted with a liquid solvent. The invention further provides for the use of a coating or treatment to increase the hydrophilicity of the surfaces, as well as the use of airflow straighteners and mechanisms to steer the surfaces.

Problems solved by technology

Capture of carbon dioxide on board of a vehicle while possible in principle is not practical because of the large amount of weight involved.
Efficient capture of carbon dioxide from air requires a sorbent that can absorb CO2, processes that heat or cool the air, or that change the pressure of the air by substantial amounts will be energetically disadvantaged.

Embodiment Construction

[0029] The present invention is directed to methods and devices to capture carbon dioxide by absorption into a strongly alkaline solution. Although general for sorbent recovery already exist, the present invention include an apparatus designed to expose alkaline fluids to atmospheric air where these fluids absorb CO2.

[0030] An apparatus that performs this task is the first in a series of modules that together provide air capture capabilities. The system discussed here differs from previous CO2 scrubber designs in that it is optimized for capturing carbon dioxide from air rather than scrubbing air clean of CO2. As a result uniform extraction from the air or maximum reduction of the CO2 content of the air are not at issue, what matters is maximizing the rate of CO2 uptake by the sorbent fluid.

[0031] Such technology would provide the ability of delivering gasoline, diesel or other carbonaceous fuels that are effectively carbon neutral because already prior to their combustion and amo...

Abstract

The present invention is directed to methods for carbon dioxide from air, which comprises exposing solvent covered surfaces to air streams where the airflow is kept laminar, or close to the laminar regime. The invention also provides for an apparatus, which is a laminar scrubber, comprising solvent covered surfaces situated such that they can be exposed to air streams such that the airflow is kept laminar.

Description

CROSS REFERENCE TO PRIOR APPLICATION [0001] This application claims the benefit of U.S. Provisional Application No. 60 / 603,121, filed Aug. 20, 2004 and is incorporated by reference in its entirety.[0002] This patent disclosure contains material that is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure as it appears in the U.S. Patent and Trademark Office patent file or records, but otherwise reserves any and all copyright rights. FIELD OF THE INVENTION [0003] The present invention relates generally to the field of extractors, including those that work to extract carbon dioxide. The present invention relates to carbon dioxide (CO2) removal under ambient conditions from the open air without heating or cooling the air. BACKGROUND OF THE INVENTION [0004] Extracting carbon dioxide from ambient air would make it possible to use carbon based fuels and deal with the greenhouse gas emi...
