Chlorobenzenes and polychlorinated biphenyls

Article Abstract:

Hydrochloric acid within flue gas, at certain concentrations, will reduce the recovery amount of some of the congeners of dichloro- to decachlorobiphenyls (PCBs) and some of the cogeners and isomers of dichloro- to hexachlorobenzenes (CBs). The effect of the acid is most pronounced at concentrations of 2.05 mg/L and 5.53 mg/L and with CBs that have fewer chloro substitutions. In fact, the recovery of CBs with five and six chlorine atoms were not affected by the presence of hydrochloric acid. The acid was also not effective in reducing the recovery of the PCBs.

Chlorophenols

Article Abstract:

A study was conducted on the influence of HCl on the recoveries of semivolatile organic compounds sourced from the adsorbent XAD-2 of the MM5 train and from condensate and ethylene glycol. The complete set of semivolatile organic compounds found in Canadian emission guidelines were analyzed. The results suggested limitations of the MM5 method in sampling incinerator flue gas having high HCl concentrations.

Effect of hydrochloric acid on sampling and analysis of semivolatile organic compounds in incineration flue gas. 2. Polycyclic aromatic hydrocarbons

Article Abstract:

Hydrochloric acid contained in incinerator flue gas affects the sampling and analysis of all semivolatile compounds, especially when sampling is done upstream in the incinerator's scrubber. The research attempts to provide the effects of HCl on 16 polycyclic aromatic hydrocarbons adsorbed through the Modified Method 5 for sampling and analysis of semivolatile organic compounds in flue gas.
