Patent ID: 8475160

Claim:
A method of reducing pollutants within a hot reaction fluid formed by reacting reactant fluid comprising a reactant with oxidant fluid comprising an oxidant, diluted by diluent fluid comprising a diluent, within a reaction system having an upstream primary reaction region and a downstream equilibration system having a first equilibration region; the method comprising: generating hot reaction fluid within the primary reaction region; equilibrating the hot reaction fluid within the equilibration system for a residence time greater than a prescribed residence time; and reducing the temperature of the hot reaction fluid within the equilibration system to less than a prescribed temperature at the system outlet; wherein configuring the fluid composition, temperature, residence sequential flow profile sufficiently: to reduce the volume concentration of unreacted reactant components in the hot reaction fluid at the system outlet to less than 25 pmvd at a 15% O 2 basis; to reduce the volume concentration of residual dissociated reaction product in the hot reaction fluid at the system outlet to less than 25 pmvd at a 15% O 2 basis; and to constrain the volume concentration of byproduct oxidation components formed within the reaction system to less than 25 ppmvd at a 15% O 2 basis at the reaction system outlet.
