Patent ID: 6974565

Claim:
A system for dry removal of target pollulants from a gas, comprising: A. at least one feeder containing a supply of sorbent of regenerable oxides of manganese and/or regenerated oxides of manganese; wherein the at least one feeder is configured to handle and feed oxides of manganese which, upon regeneration, are in particle form and are defined by the chemical formula MnO X , where X is about 1.5 to 2.0 and wherein the oxides of manganese have a particle size of less than about 0.1 to about 500 microns and a BET value ranging from about 1 to about 1000 m 2 /g; B. a modular reaction unit comprised of at least three (3) interconnected bag houses configure to receive gas and sorbent, the bag houses being connected so that a gas containing target pollutants, including at least a first target pollutant and/or a second target pollutant, can be routed through any one of the bag houses, any two of the bag houses in series, or all of the at least three bag houses in series or in parallel, or any combination of series and parallel, each bag house being separately connected to the at least one feeder so that sorbent can be introduced into each bag house where first and/or second target pollutant capture can occur when the gas is contacted with sorbent for a time sufficient to allow formation a first and/or a second reaction product formed by reaction between the first and/or second target pollutant and the oxides of manganese; and C. a controller for simultaneously monitoring and adjusting system operational parameters, the controller providing integrated control of system differential pressure and other operational parameters selected from the group consisting of first and/or second pollutant capture rate, gas inlet temperature, sorbent feed rate and any combination thereof, wherein differential pressure within the system is regulated so that any differential pressure across the system is no greater than a predetermined level and the first and/or second pollutant are removed at targeted capture rates.
