Patent ID: 8591844

Claim:
A flue gas conditioning system having a reduced start-up time, comprising: a heating device configured to preheat a flue gas stream upstream of a gas removal unit; wherein the gas removal unit comprises a catalyst and is fluidly coupled to the heating device, and wherein the gas removal unit is configured to (a) receive the preheated flue gas stream, and (b) allow for heat exchange between the preheated flue gas stream and the catalyst such that the catalyst in preheated; wherein the gas removal unit is further configured to (a) receive a reagent and (b) selectively remove a reactive gas from the flue gas stream using the preheated catalyst and the reagent to produce a scrubbed stream that is substantially depleted of the reactive gas; and wherein the heating device is configured to operate when a temperature of the catalyst is less than approximately 300° C.
