will be minimized 4 droplet burning which leads to soot formation will be suppressed 5 atomization droplet breakup and vaporization of the injected spent acid spray are enhanced because of increased shear stresses and improved heat transfer turbulence can be generated within a reactor with a variety of techniques often for gases the most practical approach is utilization of judiciously located and oriented high velocity jets or injectors mass entrainment of reaction products by the discharging jets entering the reactor create extensive turbulence and mixing either high velocity subsonic streams at velocities greater than about 100 ft sec or supersonic streams at velocities greater than 1200 ft sec or a combination of such flows will create extensive turbulence and mixing in a properly designed reactor gaseous streams that can be used to create turbulence within the oxidation reactors are reaction products from the auxiliary burner or furnace products from previous oxidation reactors cooling air secondary air and when used atomization air it is essential in the practice of this invention that very small cool spent acid droplets be injected into hot turbulent gaseous reaction products in a manner that minimizes their evaporation or vaporization time and h 2 so 4 dissociation time the spent acid should not be heated prior to atomization and injection into the reactor since heating will cause rapid liquid phase decomposition of the acid into so 2 preferably the acid feed should be cooled to or even below room temperature prior to atomization as long as the liquid viscosity remains.
