A laboratory method has been developed to provide an estimate of the amount of hydrogen chloride gas that will form during incineration of a waste. The method involves heating of a sample of the waste to 900 C in a tube furnace, removal of particles from the resulting gases by filtration, collection of hydrogen chloride gas in a water-filled impinger, and measurement of the collected HCl as chloride using ion chromatography. The original goal of the project was to develop a method which would allow accurate determination in the laboratory, of the amount of HCl formed upon full-scale incineration of a given hazardous waste feed material. Although the laboratory equipment and procedures performed as designed, the data show that results are very sensitive to materials of construction, availability of hydrogen, and probably other factors difficult to translate accurately from laboratory to full-scale equipment. It is recommended that the current interim procedure of using total chlorine in the waste feed to estimate worst case emissions be carried on as the permanent procedure. As specified in the interim procedure, sampling for HCl before and after the scrubber will be required for efficiency determination.
