Patent ID: 8685151

Claim:
A system for contaminant removal from a gas, comprising: (a) at least two reactors capable of operating in parallel to remove contaminants from a gas, wherein each reactor comprises a self-contained, fluidized sorbent bed capable of removing contaminants, and wherein each reactor is capable of regenerating said fluidized sorbent bed to produce an off-gas and a regenerated sorbent; (b) at least two in-line sensors capable of measuring the levels of specific gaseous compounds entering or leaving said reactors; (c) an electronic control system that controls the cycling of said reactors between adsorption and regeneration mode, said control system comprising: 1) a computer processor that processes data acquired from said in-line sensors according to defined parameters, wherein said parameters are programmed into a machine language that is stored on a computer-readable storage medium, and wherein said machine language provides an instruction set to said processor that allows it to propagate a signal; 2) at least two valves that receive the signals from said processor to control the flow of the various process gases into the reactors while minimizing changes in temperature and pressure and moderating the rate of said changes to decrease the attrition rate of the sorbent; wherein the control system is configured to maintain each reactor at a temperature above about 100Â° C. and a pressure above about 20 psig.
