The present invention is based on the use of surface adsorption to capture CO.sub.2 molecules from air, without requiring the need for bulk absorption within the bulk of the sorbent. Since surface adsorption is a much faster process than bulk absorption, the present invention offers a greatly increased CO.sub.2 capture rate, as well as a greatly improved energy efficiency, over conventional systems. The invention involves the use of a molecular monolayer of CO.sub.2 sorbent, a process and a system for capturing CO.sub.2 from air employing such a molecular monolayer of CO.sub.2 sorbent.

At least a portion of the contaminants from the airflow is to be destroyed at least one of directly or indirectly via the microwave energy.

Method and apparatus for condensing a majority of the solvent in a process gas stream at low temperatures, e.g., below the freezing point of water, ca. −5° C. The gas stream exiting the condenser step may be further processed in one or more emission control devices, such as a single or multi-step series of concentrator devices, such as zeolite concentrator devices. One or more emission control operations can be carried out downstream of the single or multi-step concentrators. The aforementioned condensing process enables the one or more concentrators to operate in a favorable temperature range for removal of 99% or more of VOC, thereby meeting or exceeding strict environmental regulations.
