VOCs Waste Gas Recovery Project for Plastic Packaging Industry

Project Background

With increasingly stringent environmental regulations, industrial enterprises face stricter requirements for controlling volatile organic compound (VOCs) emissions. In the plastic packaging and gravure printing industries, large amounts of organic solvent vapors are generated during printing and lamination processes. Direct release of these gases into the atmosphere not only causes environmental pollution but also wastes valuable recyclable solvents.

This project is a support project for an environmental protection company client exporting to Indonesia. The plastic packaging production process generates toxic gases, necessitating a reliable gas delivery solution capable of safely transporting the recovered organic gases and ensuring zero leakage throughout the entire operation.

Project Challenges

Unlike traditional ventilation systems, VOCs recovery projects involve combustible and volatile organic gases. Gas delivery equipment must not only provide a stable airflow but also meet stringent safety and sealing requirements.

This project faces the following technical challenges:

●Continuous delivery of combustible organic gases

●Extremely high sealing performance to prevent gas leakage

●Long-term stable operation under continuous production conditions

●High fan efficiency to reduce operating costs

●Reliable solvent recovery system performance

To meet these requirements, traditional industrial fans are not suitable.

SIMO BLOWER Solutions

Based on customers' operating conditions and process requirements, SIMO BLOWER has designed and manufactured customized MQ series gas booster fans specifically for VOCs recovery systems.

These fans are responsible for transporting the organic gases recovered during the production process to the solvent recovery unit, maintaining stable system pressure, and ensuring continuous gas circulation throughout the recovery process.

The customized design enables the entire recovery system to operate efficiently while meeting stringent environmental and safety standards.

Key Engineering Features

Zero-Leakage Sealing Design

Preventing leakage is paramount due to the presence of volatile organic compounds (VOCs) in the transported gas.

The blower employs a customized shaft seal solution combined with precision machining technology, significantly reducing the risk of gas leakage and enhancing operational safety.

This design also helps maintain stable system pressure and improves solvent recovery efficiency.

High-Efficiency Aerodynamic Performance

The impeller is optimized using advanced aerodynamic analysis, reducing energy consumption while providing stable airflow and high pressure.

Operating near the Optimal Efficiency Point (BEP) helps reduce energy costs and improve overall system efficiency.

Precision Manufacturing Process

To ensure long-term reliable operation, all critical components are manufactured under rigorous quality control procedures.

Production processes include:
●CNC laser cutting for high dimensional accuracy
●Precision welding for enhanced structural strength
●Dynamic balancing conforming to ISO 21940 G2.5 standards
●Comprehensive performance testing before delivery
●These manufacturing standards help minimize vibration, reduce maintenance needs, and extend equipment lifespan.

Application Scenarios
●Customized gas booster fans are integrated into customers' VOCs recovery processes, primarily for:
●Organic solvent gas delivery
●VOCs collection systems
●Solvent recovery equipment
●Plastic packaging production lines
●Gravure printing exhaust gas treatment systems
●The fan provides continuous and stable gas delivery while supporting efficient solvent recovery and environmental compliance.

Customer Benefits

After installation, the customer achieved several operational improvements:

1. Stable gas delivery throughout the recovery system

2. Reliable zero-leakage operation, enhancing production safety

3. Improved solvent recovery efficiency

4. High-efficiency fan performance reducing energy consumption
