Do laboratory testing of a continuous emissions monitor for hydrochloric acid?
The focus of this study was.an evaluation of the operation performance of a tunable diode laser (TDL) for the measurement of hydrochloric acid (HCl) over a range of real-world operating environments. The results showed good instrument accuracy as a function of changing temperature from 25 degrees C to 200 degrees C and moisture from 0% to 4%. Such as an instrument could be used for continuous monitoring of exhaust flue gas in power plants once the Federal Mercury and Air Toxics Standards (MATS) standards have been fully implemented.
The severity of hypothyroidism when first detected during follow-up is of concern and suggests that closer monitoring of thyroid function is required, particularly during the first 6 months post- RI therapy.
