| • Material handling section | |
| Feeding process | powder raw material escape (particle size distribution 0.1–50 μm), solvent instantaneous volatilization (peak 800–1,200 mg/m³) |
| Stirring process | breathing waste gas containing unreacted monomer (butyl acrylate 50–200 mg/m³), including resin droplets (viscosity >1,000 cP) |
| • Storage conveyer section | |
| Tank area breathing gas | temperature difference between day and night leads to small breathing emissions (air volume fluctuation 200–500 m³/h), containing C6–C12 alkanes (60–80%) |
| Sub-packing operation | VOCs escape at filling mouth (ethyl acetate concentration gradient 300–1,500 mg/m³), instantaneous emissions account for 40% of the total |
| • Special pollution source | |
| Laboratory ventilation | the components of the experimental waste gas are complex, diverse in nature, and the average daily emission time is <4 h |
| Hazardous waste storage room | organic waste liquid volatilization produces benzene series/aldehydes and ketones mixture (concentration background value 50–80 mg/m³) |
