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°C at an interval of 100°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°C than at 700°C. Studies at 800–1,000°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°C with increase in airflow rate from 2–4 L min − 1. At 900°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°C with airflow rates of 1–3 L min − 1, while less amount of 2B PAHs was found at 700°C and 800°C (with airflow rate of 1–2 L min − 1), at 900°C (with airflow rate of 1–3 L min − 1) and at 1,000°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°C with airflow rate of 1–2 L min − 1.
