Scrubber system for removing carbon dioxide from a metal-air or fuel cell battery
First Claim
1. A method for maximizing the effective life and utilization of CO2 -absorbent material in a scrubber system for removing carbon dioxide from an air inflow to a metal-air battery or fuel cell, the method comprising the steps of:
- providing, in such a battery, a housing including a gas inlet, a gas outlet, and a plurality of gas-permeable containers supported in series across the flow path of gas entering said inlet and exiting said outlet;
each of said containers containing a CO2 -absorbent material and being individually independently removable from said series; and
flowing gas containing CO2 into said gas inlet, through said CO2 -absorbent material in each of said plurality of containers, and out of said outlet,wherein, after a utilization of the system, a first container closest to said gas inlet is removed from said series and a second container from said series is repositioned in the place of said first container and spent CO2 -absorbent material from said first container is regenerated for reuse in said scrubber system, said regeneration including at least periodically removing accumulated Group 1a metal carbonate deposits.

Abstract
A method for maximizing the effective life and utilization of CO2 -absorbent material in a scrubber system for removing carbon dioxide from an air inflow to a metal-air battery or fuel cell comprises providing, in such a battery, a housing including a gas inlet, a gas outlet, and at least one removable, gas-permeable container containing a CO2 -absorbent material, the container being positioned across the flow path of gas entering said inlet and exiting said outlet. After a predetermined utilization of the system, the at least one removable, gas-permeable container is removed therefrom and spent CO2 -absorbent material from the container is regenerated for reuse in the scrubber system, the regeneration including at least periodically removing accumulated Group 1a metal carbonate deposits.
