Solution Overview
Flexible packaging printing, including food packaging, book printing, banknote printing, and consumer product packaging materials, produces high-concentration VOC emissions during production. Proper VOC capture and RTO treatment are critical to maintain product quality, ensure safety, and reduce environmental impact.
AuSSE delivers integrated exhaust gas treatment solutions specifically for flexible printing facilities.
Industry Characteristics
VOC concentrations are high, typically 500–5000 mg/m³. Printing quality is closely linked to VOC levels: higher quality often requires higher VOC concentrations.
VOCs are released in unorganized ways. High-speed printing presses and human activity can disrupt airflow, making capture outside drying zones difficult.
High-concentration VOCs combined with reduced airflow can exceed the lower explosive limit (LEL). High-speed operations generate static electricity, posing fire and explosion risks.
Due to strict printing quality requirements, condensation recovery is not suitable, and recovered solvents often cannot be reused.
Engineering Challenges
High and fluctuating VOC concentrations
Unorganized emissions and difficult capture points
Safety hazards from static electricity and explosive limits
Limited solvent recovery options
AuSSE Integrated VOC Treatment Solution
AuSSE provides tailored RTO and VOC treatment solutions for flexible printing operations.
RTO Design Based on Concentration
We design RTO systems according to VOC concentration. This prevents overheating and frequent system shutdowns, ensuring stable production.
Closed Operations for Unorganized Emissions
We implement enclosed collection in areas with unorganized VOC discharge to limit spread and improve capture efficiency.
Safety Interlocks and LEL Monitoring
LEL monitoring devices are installed. When VOC concentration exceeds safety thresholds, interlocking operation prevents fire and explosion hazards.
Anti-Static Measures
Both production equipment and the environmental control system are treated to reduce static electricity risk.
RTO Fuel Utilization
High-concentration VOCs that cannot be recycled are used as RTO fuel. This reduces operating costs while ensuring safe disposal.
Heat Recovery
Heat from the RTO outlet can be used to support other facilities, such as canteen hot water, dormitory heating, or employee showers.
Project Experience in Flexible Packaging Printing
