RTO for Chlorinated VOCs in Fine Chemical Industry | RTO with Heat Recovery Solution
Industry Pain Points of Chlorinated VOCs Treatment in Fine Chemical Industry
In the fine chemical and pharmaceutical industries, chlorinated VOCs exhaust gas treatment is one of the most challenging environmental issues.
1.Severe Corrosion from Chlorinated Exhaust Gas
Acid gases such as HCl and chlorinated VOCs cause serious corrosion.
Conventional RTO systems typically last less than 2 years, with maintenance costs exceeding RMB 1 million annually
2.Strict VOCs Emission Regulations
Regulations require VOCs removal efficiency ≥95%, while some industrial parks demand near-zero VOCs emissions, making RTO for VOCs compliance essential
3.High Energy Consumption in VOCs Treatment
Steam costs account for 30%–40% of production costs, and traditional systems lack heat recovery efficiency
4.Carbon Reduction Pressure (Low-Carbon VOCs Treatment)
Increasing pressure for carbon neutrality requires energy-efficient RTO systems with heat recovery
