Effect of combustion variables on PAHs emission from incineration of cellulose waste filters from acrylic industry.
Incineration of cellulose waste filter from acrylic industry showed the presence of 13-16 polycyclic aromatic hydrocarbons (PAHs) from the list of 16 priority pollutants with an airflow rate of 1, 2, 3, and 4 L min(-1) in laboratory scale quartz tube vertical incinerator at 700-1,000 degrees C at an interval of 100 degrees C. The amount of total 16 PAHs increases with the increase in temperature with airflow rate of 1 L min(-1) and was found to be 9.4 times at 1,000 degrees C than at 700 degrees C. Studies at 800-1,000 degrees C showed the decrease in total 16 PAHs with increase in airflow rate from 1 to 2 L min(-1). The amount of total 16 PAHs increases at 700, 800, and 1,000 degrees C with increase in airflow rate from 2-4 L min(-1). At 900 degrees C, amount of 16 PAHs decreases with increase in flow rate from 1 to 3 and increases at 4 L min(-1). The lesser amount of 2A PAHs was found at 700-900 degrees C with airflow rates of 1-3 L min(-1), while less amount of 2B PAHs was found at 700 degrees C and 800 degrees C (with airflow rate of 1-2 L min(-1)), at 900 degrees C (with airflow rate of 1-3 L min(-1)) and at 1,000 degrees C (with airflow rate of 3 L min(-1)). However, the sum total of 2A and 2B PAHs were found to be less at 700-900 degrees C with airflow rate of 1-2 L min(-1).
