The industrial internet of things (IIoT) combined with remote operations and maintenance promise to make the reduction of air pollutants by thermal treatment much more cost effective. Thermal treatment includes flaring, controlled combustion, catalytic oxidation, regenerative catalytic oxidation and regenerative thermal oxidation. For some applications, there are chemical challenges with a range of toxics to be removed, but the toxics which can be formed in the process need to be considered. Where there are low fuel values such as solvent treatment from textile or printing operations, it is economical to use regenerative oxidizers. This means alternating flow through three large vessels with lots of dampers, valves, and other components which must be optimally controlled. Another variable is product value. Low value solvents might be used in the morning and they can be combusted but if high value solvents are used in the afternoon they can be recovered. In an oil shale operation, byproduct gas can be flared when gas prices are low and captured when prices rise. The cost of common sensors to measure temperature, pressure, etc. are shrinking. New instruments such as tunable diode lasers can measure O2 and CO at any point in a combustor. These developments create a $21 billion opportunity for suppliers.
