CCL Label (Hefei) Co., Ltd

Source of Waste Gas:  
The waste gas originates from two main sources: organized emissions from printing and compounding machines, as well as unorganized emissions from workshops.

Design Air Volume:
The system is designed with a capacity of 40,000 m³/h for the Rotary Valve RTO, complemented by a 50,000 m³/h zeolite rotor.

Waste Gas Concentration:
The concentration of organized waste gas ranges from approximately 3,000 mg/m³ to 5,000 mg/m³, while unorganized emissions are around 600 mg/m³.

Waste Gas Components:
The primary components of the waste gas include ethyl acetate, n-propyl ester, isopropanol, and others.

Process Scheme:
The treatment process involves air reduction and concentration, followed by processing through a Rotary Valve RTO and a zeolite rotor. Additionally, waste heat recovery is integrated into the system, utilizing a steam waste heat boiler.

RTO Model: 40,000 m³/h Rotary Valve RTO.

Emission Limits:
The emission limit for non-methane hydrocarbons (NMHC) is set at ≤ 50 mg/m³.
