Abstract |
Infrared spectral study of industrial stack plumes was performed to investigate the feasibility of pollution efflux monitoring by remote observation. The conclusions of this study are: (1) Measurement of industrial stack pollution rates is feasible with simple optical systems using common optical components and relatively inexpensive detectors. However, a degree of sophistication is necessary in the electronics to remove the burden of exponential calculations from the operator/analyst. Such computations are amenable to state-of-the-art analog computational techniques. (2) A large number of a parameters are significant in reception of radiation from a given plume. For a low temperature process this can result in rather complex organics being generated which tend to clutter the spectra. (3) Pollution densities over 0.3% are readily determined quantitatively for most gases when the plume temperature is over 200F, when a small to moderate amount of particulate or other gray body radiation is present. (4) Coal burning systems produce a minimum of H2O vapor which obscures SO2 to a degree; coal burning power plants are expected to show distinct SO2 spectra at densities as low as 50 ppm when the particulate exhaust is under control.
