April 20, 1977. revealed an absence of vinyl chloride In flue gas exhaust. EPA Test Method 106 . mss used to examine No. 12 Boiler exhaust gas (cycrantly being used to Incinerate vinyl ehlorlde vent amissions from the SVR Unit) and also that from No. 15 and 16 Boilers. Fuel used In No. 12 Boiler during the three-hour test period Included odor gas&from the odor abatement header, vinyl chloride vent emissions, natural gafeand coal, in addition to coal and natural gas. fuel burned In No. 15 and 16 Boilers during the test period Included ethyl hexoie acid heads (residues) from Acetic Esters Unit and residues fpom Specialty Resins Unit containing acetone, styrene, and methyl acetate. A report that vinyl chloride could be generated as a combustion product from various eairiiHitlble materials, e.g., VC1 has reportedly been Isolated In tobacco smoke, prompted testing No. 15 and 16 boilers. Then too. concern has been expressed, both. Internally and by the WVAPCC, about HC1 emissions from the IPH. As the compliance testing was conducted for vinyl chloride emission*. the sane boiler exhausts were simultaneously analysed for chlorides and calculate*; as hydrogen chloride.'1' HCI emission rate from No. 12 bolter atconditions STf was 0.2 lbs/hr. The total rate from No. 15 and 16 Boilers exhausting through a common duct was Ibs/hr. 1.1 . Hence, our conclusion Is thatt . 1. TharmSl destruction of vinyl chloride is complete at the higk temperatures In the boiler furnaces, and, 2. HCI emissions resulting from Incineration of vinyl chloride appears to bg negligible, compared to "background" emissions from com- , bustled of the various forementloned fuels containing no vinyl ' chlorldei * ACKNOWLEDGEMENT The assistance provided by Messrs.
