STATEMENT UNDER ARTICLE 19 (1 )
After reviewing the citations of ISR, the applicant has amended the claims and the same are enclosed herewith.
The present invention relates to an improved system and method for removing carbon dioxide from a re-circulating gas stream by means of a carbon dioxide adsorbent resin, wherein the said gas stream is derived from a breathable atmosphere in a closed habitat environment. The main aspect of the invention is to provide a system for removing carbon dioxide (CO?) particles in a closed environment of high carbon dioxide concentration in a manner such that the CC is removed from the air at a higher pace and the sorbent beds are regenerated in lesser time- Further, the system incorporates additional provisions for removal of byproducts of the system and thus providing recycling of fresh breathable air.
The cited arts either relate to C02 scrubbers for manufacturing premises or system for C02 removal using sorbent beds without removing the byproducts of the process itself. The cited art further lacks the pace and regenerative efficiency as indicated in the present invention.
The claims are amended so as to differentiate the invention from the cited arts. The independent claimsl and 8 have been amended to further characterize the present invention.
The following table describes wherein the changes made in the claims along with the basis of such amendments are mentioned:
